The Standalone System
The Graphtec GL840M is a high quality 20 channel datalogger that is expandable up to 200 total channels. Each channel is isolated. This unit is suitable for many applications including temperature measurement with multiple channels. The built in 7 inch color display provides an intuitive data viewing experience. Although this system is designed as a standalone unit, it can be connected to a PC if needed. Communicate with up to (5) GL100 units with B-568 Wifi module.

Multifunction analog input ports
The GL840M has been designed with an extremely isolated input system ensuring that all signals are left unaffected by outside channel noise. With this capability, this system can be used for a variety of applications including voltage, humidity, temperature, pulse and logic.
The GL840M comes standard with 20 analog input channels but it is easily expandable up to 200 channels by adding the optional 20 channel extension terminal base (B-566) and other input terminal units (B-564 or B-565).
