GRAPHTEC GL260 Multi-Channel Data Logger (midi LOGGER) | 10 fully isolated channels, fastest 10 ms, 4.3-inch color display, approx. 8 GB internal + SD card, USB

GRAPHTEC GL260 Multi-Channel Data Logger: 10 Fully Isolated Channels

Overview

The GL260 is a 10-channel handheld data logger in the GRAPHTEC (Japan) midi LOGGER series. Each channel is isolated, and voltage and thermocouple temperature are measured by scanning; humidity can be measured with the optional humidity sensor B-530. Data is stored in approx. 8 GB of built-in flash memory and on an SD card, and the logger connects to a PC via USB, with setup and data conversion software included. The main unit has no wired network port; the optional B-568 enables wireless LAN (the SD card cannot be used when it is installed). The optional B-569 lithium battery pack allows field use. For applications needing more channels, ask about the GL860 7-inch model: 20 channels with input terminals such as the B-563, expandable to up to 200 channels.
