Overview

The POLWAX MOTUS MR800 is a portable 8-channel datalogger for recording temperature and process signals in the field. Universal inputs accept RTD Pt100, thermocouples (types B, E, J, K, L, N, R, S, T), 4-20 mA and 0-10 V signals, so it can be used with POLWAX and third-party sensors and transmitters.

Measurements are shown on a 3.5" touch screen display and can be read out over USB and RS485. The MR800+ adds Ethernet (Modbus TCP) and the MR800PRO adds Ethernet and WiFi. Reports are produced in PDF, CSV or XLSX format with POLWAX_View software; an optional web-based cloud dashboard is available.
