THE SMARTQ DIFFERENCE

Beneath SmartQ’s simple and bright exterior is a revolutionary architecture that
dramatically enhances the intelligence, accuracy and value of the entire range of
sensors. Among many of the remarkable improvements of the SmartQ design is the
incorporation of a microprocessor that enables the production team to individually
calibrate every single sensor digitally. You will be astounded by the accuracy and
reliability of the sensors

SMARTQ SENSORS & ACCESSORIES

1 A CCELEROMETER

1 ACCELEROMETER 2 B ALANCE ADAPTOR The accelerometer is an electromechanical device that will measure
acceleration forces. These forces may be static, like the constant force of
gravity pulling at your feet, or dynamic - caused by moving or vibrating the
accelerometer.

There are 2 accelerometer sensors, one recording accelerations to a maximum
of 10g and one recording accelerations to a maximum of 40g.

The lower range sensor can record acceleration in one of 3 axis or the resultant
force of the 3 axis. It will also measure vibration forces and angle. The higher
range sensor is restricted to 2 axis and resultant forces of both axis. Both
sensors will show the acceleration as multiples of g or as ms-2.

4 CARBON DIOXIDE

This sensor demonstrates that packaging does make a difference. The upper
circular lid casing has been cleverly designed to form sealed chambers using
standard laboratory beakers and conical flasks.

The casing also provides ports for inserting additional sensors into the chamber
such as temperature, pH, and fOro2m. Tthhee actual sensing element resides in a
vented capsule that protrudes lower side of the sensor.

The sensor can be set at two ranges enabling measurements from a wide
variety of sources.

3 D ROP & BUBBLE COUNTER

This sensor offers exceptional value as it performs a dual role. In Chemistry its
primary role is as a drop counter measuring accurately the volume of titrant
added during a titration. However, this sensor can also be used to monitor
bubbles produced during gas production from either a chemical reaction or a
biological process.

When operating as a drop counter, titrant is uniformly dripped from the 4 CURRENT SENSOR
supplied reservoir and optically recorded. If desired, the drops can be
automatically converted to a volume measurement by following a simple
calibration procedure.

As a bubble counter, the sensor optically counts the number of bubbles,
from either a chemical or biological source, ascending through the plastic
tubing. This method is unique in that it accurately measures the range of gas
production and is ideal for biological investigations.

Ranges:

• 0 to 10,000 count

These simple mini dataloggers are exceptionally priced and are available in
two versions - temperature or light. The dataloggers are in the form of a USB
stick, so no cables are required to retrieve data or configure the device. The
sensor, memory and battery are all encapsulated on a single circuit so no
additional hardware is required (battery life is estimated at up to 10 years).

The sample rate can be set between once per second and once every 12 hours,
hence the 640 sample memory can store from 10 minutes to almost a year
of data! Where a faster sample rate is desired for short experiments, the mini
datalogger can be used in burst mode. May be used outside or in a liquid if
protected in a self-seal bag or container.

To use, simply insert into a USB port in your computer and launch the software 3 ECONOMY MINI DATA
to configure the data logger - i.e. set the frequency of the readings; Remove LOGGER, ACCELEROMETER
from the computer and place the datalogger wherever readings are required;
Readings are recorded automatically at the frequency set during configuration;
Insert back into the computer to download the data when required and view
or export to a spreadsheet via the software (downloadable using the link
supplied).

1 SLINKY SPRING SEISMOMETER 1 S LINKY SPRING 2 S EISMOMETER INTERFACE
SEISMOMETER
Designed in association with the British Geological Survey, this ‘slinky’
seismometer provides an elegant, low-cost solution to earthquake detection.
The seismometer uses electromagnetic induction to detect ground motion and
incorporates eddy current damping for improved sensing. Supplied in kit form,
the seismometer is quick and easy to assemble. Connections are made via a
twin core wire, pre-connected to the coil.

The slinky seismometer requires a suitable digitiser, such as the USB
seismometer interface EA150900, and software such as the popular AmaSeis
(which is free to download).

Step by step instructions are included for setting up the kit.

4 VOLCANOES & EARTHQUAKES KIT

Earth is constantly changing - massive pieces of its outer layer are slowly
sliding under, over, away from, or past each other. Earthquakes shake the
continents and oceans, and volcanoes spew out the molten insides of our
planet. By studying these awe-inspiring and devastating natural phenomena,
you can learn more about the inner workings of Earth. A full-colour, 48-page
experiment manual is included.

• Build and erupt a model volcano with plaster-based “lava” that hardens
• after each eruption.

Volcano can be erupted multiple times - volcanic cone builds up with
each eruption, like a real volcano.

• Learn about the different types of volcanoes.
• Build a working seismograph and simulate earthquakes to see how
• scientists measure earthquake forces.

Discover plate tectonics, and see how volcanoes and earthquakes are

• caused by the constant movement of the planet’s parts.
Assemble a plate tectonics puzzle and a geological globe. Play a volcano
quiz game to learn about well-known volcanoes.

RICHTER SCALE INFO

The Richter scale, devised by Charles Richter in 1935, is a quantitative measure of the magnitude of TECHNICAL
an earthquake.
It is a Base 10 Logarithmic scale i.e. each whole number increase corresponds to a 10 times increase in amplitude.
For example, an earthquake of magnitude 5 on the Richter scale will be 10 times more powerful than a magnitude 4.
An increase in magnitude of 1 unit also equates to an approximately 32 times increase in energy released overall
during an earthquake.
The Amplitude of the Seismic (shock) waves gives a measure of ground movement during an earthquake i.e. the
speed or acceleration of sudden ground movements (shaking) – detected by Seismometers, recorded by Seismographs
and represented graphically as Seismograms.
The Richter Scale has no specified upper limit but is generally quoted on a scale of magnitudes between 0 and 9 (and
decimal fractions in between) – due to the fact that no earthquakes have yet been recorded above magnitude 9.

LED MAINS LIGHT BULBS – WATTS, LUMENS & COLOUR TEMPERATURE

• LED bulbs consume far less energy than traditional incandescent (tungsten filament) or halogen bulbs and, unlike fluorescent and compact

fluorescent bulbs and tubes, they do not contain any mercury. Also, they do not take time to warm up to full brightness but glow at full brightness
almost as soon as they are switched on

• Traditionally the brightness of light bulbs is rated by power (in Watts). However, since the introduction of LED mains lighting, the brightness of bulbs

is starting to be rated in lumens - the higher the number of lumens, the brighter the light. This is because LED bulbs use so much less power and it
is difficult to know how bright the bulbs are without stating an equivalent rating in Watts, for comparison with the old-type incandescent bulbs. The
actual power rating should still also be stated (in Watts)

• Please be aware that LED bulbs can only be used with dimmer switches if they are of the dimmable type

Equivalent brightness of different bulb types (approximate only)

Tungsten filament (incandescent) 25W 30W 40W 60W 75W 100W

Halogen 18W 21W 28W 42W 53W 70W

Compact Fluorescent (CFL or low energy) 5W 6W 8W 12W 15W 20W

LED 4W 5W 6W 10W 13W 18W

Brightness (Lumens) ≥220 ≥300 ≥400 ≥700 ≥900 ≥1300

As a rough guide: halogen bulbs use approx. 30% less energy than incandescent bulbs; Compact fluorescent bulbs use approx. 80% less energy than incandescent
bulbs; LED bulbs use approx. 85% less energy than incandescent bulbs.

Colour Temperature

Colour temperature is used to describe the type of white light emitted. Incandescent bulbs generally emit a ‘warm-white’ light, (yellow-white) and are suitable for
less harsh (‘cosy’) house lighting etc. Halogen bulbs tend to emit a cooler white light. Fluorescent lights vary, being internally coated to emit different types of light
e.g. warm-white, cool-white or light which is biased towards different parts of the light spectrum (e.g. blue or red, for plant growth etc.). LED bulbs use a colour
temperature rating to indicate the type of white light emitted, which is stated in degrees Kelvin (K).

LED Colour temperature 1800K 2700–3000K 3000K - 4000K 4000K 5000K – 6500K

LED INFORMATION

When using Light Emitting Diodes it is strongly recommended that a 5 L OUDSPEAKERS
resistor is placed in series with the LED to limit the current and prevent
