Graphtec midi LOGGER GL840 series

Graphtec Corporation in Japan have launched their latest data logger series, the midi Logger GL840-M and GL840-WV.

Building on the success of the single GL820 model released back in 2010, Graphtec have now added to the GL range with two new data logging models.

Both new Graphtec models are multi-channel units supporting up to 200 channels using the optional expansion modules. The input channels are multi-functional and isolated. The GL840 series data loggers include enhanced data logging features and designed to be used in various types of measurement and recording applications.

The GL840 series allows for wireless communication using the optional Graphtec B-568 wireless LAN module. Using Wireless LAN module, GL840 series can recognise the Graphtec Petit LOGGER GL100-WL as the remote sensor unit.

The GL840-M is a direct replacement for the GL820 and the even earlier GL800 data loggers.

The GL840-WV model now supports higher DC voltage inputs of up to 300Vp-p, plus an improved Thermocouple cold junction accuracy. Typical applications include UPS battery monitoring and battery conditioning monitoring.
