code: M1322
Battery powered datalogger with built-in CO2 sensor and 4 universal inputs for measurement of temperature, humidity, 0-10V voltage, 0-20mA current, two-state signal and for counting pulses.
Multilogger can be installed permanently to Ethernet network or work as portable device.
Included is traceable calibration certificate in accordance with EN ISO/IEC17025.
The device is designed for measuring and recording temperature, humidity, CO2 (internal sensor) with adjustable recording intervals from 1 second to 24 hours.
Datalogger can be connected to Ethernet.
Then measured values can be viewed on a web browser, as well as stored and downloaded for later analysis.
- on-line monitoring
- recording of data
- alarm warnings
