Graphtec GL860 datalogger
Details
The Graphtec GL860 is a portable, isolated multi-channel datalogger for industrial temperature and voltage monitoring. The standard 20 channels sample at up to 5ms and are galvanically isolated to prevent cross-channel interference. Graphtec is a Japanese brand known for the durability and quality of its instruments. Data is stored internally up to 8GB, expandable with an SD card, and exports easily to CSV. Voltage, thermocouple, RTD and humidity inputs are supported on every channel.
The integrated 7" TFT display (800x480) shows live waveforms and statistics, and USB and Ethernet are included for PC control and remote monitoring. This version is the bare logger: it is supplied without an input terminal, so choose the B-563 screw terminal or the B-563SL screwless terminal to suit your wiring. The complete kit, which adds the terminal, a hard carrying case, two battery packs, accessories, a calibration certificate and an extended warranty, is available separately. Sensors are not included. Contact us if you need help selecting the right sensors.
The GL860 can be expanded from 20 up to 200 channels. Each step adds a B-566 extension module together with one or more B-563 input terminals, and the modules are linked with a B-567 cable, available in 0.5m and 2m lengths. Contact us if you need help configuring the right combination for your channel count.
