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.

Logger sensor Guide

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.

Specifications:

Experiment Duration: 1 second to 31 days.

Logger sensor Guide

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.

Logger sensor Guide

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.

Logger sensor Guide

This logger sensor is based on an electromechanical reaction between CO₂ gas and the sensor.

The result of the electromechanical reaction is voltage, measured by the logger sensor. The measure units are ppm (parts of CO₂ per million of air).

Note: The sensor must be calibrated before every use according to the following simple procedure: connect the sensor to the PC through a USB module or a battery module. Wait for about 15 minutes to warm the sensor and press the pushbutton switch on the CO₂ logger sensor for 3 seconds. Preferably this calibration should be performed in open space. A bottle adapted to the sensor is supplied.

Specifications:

Experiment Duration: 1 second to 31 days.

Logger sensor Guide

The NeuLog chloride sensor can be used to measure the concentration of chloride ions (Cl^–) in aqueous samples. This measurement can be an indication of the salinity of water samples. The sensor can be used to study samples of drinking water with different degrees of chlorination.

Specifications:

Experiment Duration: 1 second to 31 days.
