Graphtec GL840-WV Description
The Graphtec GL840-WV Compact 20 Channel Multi-Function Data Logger specifically designed for measuring battery cell voltages in battery packs or UPS systems with a max voltage to ground of 300V. The GL840-WV can be extended from 20 to up to 200 channels either as a single block of connection points or daisy chained using 0.5m or 2m connection leads allowing you to spread out the contact points reducing your wiring requirements. You can measure and record voltage levels up to 100V DC and temperatures up to 2000°C with suitable thermocouples. DC voltages can be recorded across 13 different ranges from 0…20mV to 0…100V and temperature measurement is supported by a full range of thermocouples K, J, E, T, N, R, S & B and RTD’s. The 7-inch wide TFT colour LCD display enables you to clearly view live or recorded data in wave or digital formats or a combination of both. The supplied GL840 Application Software can be utilised to program and control the Graphtec GL840 data logger, display recorded or live date in a number of different formats. The direct-Excel function enables captured data to be written directly to an Excel file. The GL840 can be controlled by a PC if connected by USB cable, allowing the transfer of data in real time. If you need to move large data files to your PC then the GL840 USB drive mode function enables data to be transferred to the PC from the GL840 by drag and drop feature.
