New products

At CMA Science, we continue to innovate constantly. This month, 4 new products have been developed in-house.

Wireless photogate with pulley

The wireless Photogate features a pair of light gates placed side by side that detect objects passing between its arms. It can be used for timing measurements with a single gate and for velocity measurements using both gates. It also supports position measurements when used with a Smart Pulley. In addition, multiple photogates can be connected in a daisy chain, allowing sequential measurements across up to five photogates.

The sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 Lite programs/apps on computers (Windows and Mac), Chromebooks, and mobile devices (Android and iOS).

Dynamic positioning system

Dynamic positioning system allows you to easily control and record position in Coach, with a resolution of 0.2 mm.
Easily plot distance versus sensor value in a graph! A CoachLab II is required for operation. This dynamic positioning system was developed by 3B for CMA. It enables fast and accurate reproducible positioning of sensors or components in experiments.

Possible experiments: inverse square law, magnetic field through a coil, light interference through two slits, and much more.

Wireless drop counter

This wireless drop counter is a sensor designed to count liquid droplets during experiments such as titrations. The sensor comes with the following accessories: a 100 ml plastic syringe with Luer-lock connection, two three-way valves with Luer-lock connections, a 1.6 mm dropper tip, and a USB-A to USB-C cable.

The sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 Lite programs/apps on computers (Windows and Mac), Chromebooks, and mobile devices (Android and iOS). The wireless drop counter is equipped with a color OLED display that shows sensor information and measured values, allowing it to be used as a standalone measuring instrument.
