The Galvanic Skin Response (GSR) logger sensor measures the conductivity of our skin, especially of our fingers.

The conductivity of our skin changes according to unconscious emotion effects such as sudden noise, smell, touch, pain or view.

This sensor has two ranges: conductivity in microsiemens and arbitrary numbers.

Specifications:

Experiment Duration: 1 seconds to 31 days.

Logger sensor Guide

This module is in fact a weight scale designed for a multi range of purposes. Simply lay a heavy weight on its surface, or activate a forceful pressure against it (like a bouncing ball), and the logger sensor will measure it. But that’s not all, once a special set of handles are attached, it can also measure pull pressure rather than just weights and presses.

Specifications:

Experiment Duration: 1 second to 31 days.

This sensor can measure the mass to weight relationship and study how different pulley systems affect the effort needed to lift weights. It can also be used to measure push/pull forces and impacts. There is a hook at the bottom of the force sensor that can be connected to various pulling loads.

The sensor can be hung from a universal laboratory stand via a rod through the hole in it.

This sensor can be operated facing upwards, downwards or at any intermediate (including horizontal) position.

Sensor zeroing

After connecting the sensor to a power source (battery module or USB module and PC), hold the sensor in its proper position and press the button in the sensor’s box for about 3 seconds.

Specifications:

Experiment Duration: 50 milliseconds to 31 days.

Identical in its use to a regular medical ECG (electrocardiogram), this is a rather simple three lead based logger sensor. It presents a heartbeat graph that allows a thorough examination of the heart’s electrical activity from three different angles. Unlike most ECG devices, this unit operates with non-disposable electrodes

Specifications:

Experiment Duration: 1 second to 31 days.

Logger sensor Guide

This sensor enables to count automatically drops and bubbles. It is perfect for titrations. Combined with the pH sensor it gives a very nice titration curve.

The sensor comes with a pre calibrated value for the drops volume. The user can make his own calibration.

Experiment Duration: 1 second to 31 days.

This sensor measures temperature and humidity in a volume and gives the temperature below which the water vapor in that volume of air (at a constant barometric pressure) condenses into liquid water (the dew point).

Specifications:

Experiment Duration: 1 second to 31 days.

Logger sensor Guide

This sensor can be used to measure the current in parallel or series branches of low voltage AC and DC circuits and also to investigate the dependence of the current flow through components on the voltage across them.

With its 4 mm plugs it can easily be connected into electric circuits.

Specifications:

Experiment Duration: 50 milliseconds to 31 days.

Logger sensor Guide

This logger sensor is based on a probe with two electrodes with known surface area and distance between them. A signal is supplied to the electrodes and by testing the signal behavior, the conductivity of the solution is calculated

The logger sensor has three ranges for displaying the solution conductivity:

• µS/cm – microsiemens per centimeter
• mg/L – milligram per liter
• ppm – parts per million

Specifications:

Experiment Duration: 1 second to 31 days.

The colorimeter measures transmittance and absorbance of red, orange, green and blue light components projected on a solution.

The colorimeter logger sensor has an opening for a special square solution cuvette. It turns on four different lights in known values and measures the received light that passes through the solution.

This sensor has two modes of operation: Absorbance and Transmitence. Note: The plastic tube (cuvette) must be put in a certain way inside the colorimeter. The cuvette has two rough sides. These sides should not be in the line of the light. Three cuvettes are supplied with the sensor.

Specifications:

Experiment Duration: 1 second to 31 days.
