COMET M1321 – Multilogger with integrated barometric pressure sensor, 2 MiniDIN + 2 terminals for Pt1000/DIGI T+RH

COMET M1321 – Ethernet Multilogger with integrated air pressure sensor 600–1100 hPa (±1.3 hPa), 2 MiniDIN + 2 terminals for Pt1000/DIGI T+RH/voltage/current/counter 

The COMET M1321 is a versatile Ethernet multilogger with an integrated barometric pressure sensor and 4 universal inputs (2× MiniDIN + 2× terminals) – the professional solution for long-term measurement and recording of temperature, humidity, dew point, and air pressure as well as additional signals (Pt1000, DIGI T+RH, 0–10 V, 0–20 mA, binary signal, pulse counter). As a network-enabled datalogger with memory for 1 million recorded values (non-cyclic) or 600,000 values (cyclic), it is ideal for indoor climate monitoring, storage areas, climate chambers, server rooms, laboratories, greenhouses, or industrial process control – wherever multiple parameters must be monitored, alarmed, and remotely accessed simultaneously.

The internal air pressure sensor measures 600 to 1100 hPa (±1.3 hPa at 23 °C). The 2 MiniDIN inputs accept Pt1000 temperature probes (−200 to +600 °C, ±0.2 °C from −200 to +100 °C, ±0.2 % above) or DIGI T+RH probes for combined temperature/humidity measurement (dew point, absolute/specific humidity, mixing ratio, enthalpy). The 2 terminal inputs measure voltage (0–10 V ±10 mV), current (0–20 mA), binary signals, or pulses. The integrated web server enables live view, configuration, and data download via a web browser – no additional software required. Acoustic/optical alarm in case of threshold exceedance. The backlit LCD displays all channels simultaneously. The logger operates independently (battery powered) or permanently via Ethernet. Recording interval 1 s to 24 h – flexible for any application.

The multilogger is maintenance-free, long-term stable, and supplied with a traceable calibration certificate (EN ISO/IEC 17025) – top quality for GMP, ISO, and audit purposes. The free PC software and web interface allow comfortable data evaluation. Battery life up to several months (depending on configuration). Whether used as a stationary Ethernet logger in a control cabinet or as a portable battery-operated device – the M1321 offers maximum flexibility and reliability. The 4 inputs allow mixed operation, e.g. 2× Pt1000 + 1× DIGI T+RH + 1× voltage.
