Wireless drop counter

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 sensor features a color OLED display that shows sensor information and measured values, allowing it to be used as a standalone measuring instrument.
As droplets pass through the sensing area, the sensor detects and records each drop automatically using an infrared detection system.
