Count/Tachometer Adaptor

Count/Tachometer Adaptor


The Count/Tachometer adapter counts electrical pulses. It contains the calibration for 11 different ranges making this a very versatile sensor for a wide range of investigations.

A Versatile Sensor

The Count/Tachometer Adaptor can count up to 60,000 cumulative events or the speed of a rotating bicycle wheel. It can be used to investigate Newton’s laws with Atwood’s machine or count red and green buses, anything where you count an event or use events per unit of time for rate e.g. revs/second, miles per hour, rpm, counts /second.

Weather Patterns

Students can study weather patterns with our environmental accessories; by recording wind speeds with our Anemometer or the amount of rain fall over time using our Rain Gauge.

Newton’s second law

Atwood’s machine provides a simple and economical way of testing Newton’s 2nd Law. Find the accelerating force by recording the difference between the weights of the two masses hanging either side of a free running pulley.

Pre-calibrated ready for use

The Count/Tachometer adaptor is pre-calibrated at manufacture making it ready to plug-in and start using with minimal setup time. Here's a selection of experiments you can achieve by using the Count/Tachometer adaptor, additional accessories are required.

Measure the distance and speed of a road bicycle
Record wind speed using an Anemometer
Record rain fall using a Rain Gauge
Get distance measurements from a spoked pulley
Study circular motion
Use with switches to count events
Muscle fatigue using a Light gate
Bike speed and exercise
Your Purchasing Options

The Count/Tachometer is supplied as a single adaptor item and designed to be used with other sensors such as an Anemometer or a rain gauge.

For customers outside of the UK, please contact Data Harvest or an overseas distributor within your country.
