COMET M1220 – Multilogger with 2× MiniDIN and 2× Thermocouple (K/J/S/B/T/N), Ethernet port

COMET M1220 – Multilogger with 2× MiniDIN (T+RH) + 2× Thermocouple (K/J/S/B/T/N up to +1700 °C), Ethernet Port, 1 Mio. Values Memory, Backlit LCD

The COMET M1220 is the universal and network-capable multilogger with 2× MiniDIN inputs for temperature-humidity probes (Digi/M series) and 2× thermocouple inputs (type K, J, S, B, T, N) – the professional all-in-one solution for combined room climate and process temperature monitoring in climate chambers, warehouses, cold rooms, server rooms, incubators, dryers, ovens, burners, pharmaceutical production, food industry, or anywhere where temperature, humidity, and high temperatures need to be recorded simultaneously. With a huge memory of 1 million measured values (non-cyclic) or 600,000 values (cyclic), integrated Ethernet port for permanent network connection, backlit LCD, and traceable calibration certificate (EN ISO/IEC 17025), it is perfect for remote monitoring, quality management, audits, ISO compliance, and GMP applications.

The 2 MiniDIN inputs accept temperature-humidity probes Digi/M (measurement range & accuracy according to probe, typically -30 to +105 °C / 0–100 %RH, dew point automatically calculated ±1.5 °C). The 2 thermocouple inputs support type K (-200 to +1300 °C), J (-200 to +750 °C), S (0 to +1700 °C), B (100 to +1800 °C), T (-200 to +400 °C), N (-200 to +1300 °C) with accuracy ±0.3 % of reading +1.5 °C (or +1 °C for type B above +300 °C). The logger stores up to 1 million values with freely adjustable interval (1 s to 24 h). The backlit LCD displays all channels simultaneously. Thanks to the Ethernet port, measured values can be viewed live in a web browser, stored, and downloaded – remote access, real-time monitoring, and automatic data transfer are possible. Data evaluation via free COMET Vision software – with tables, graphs, PDF, and Excel export. Acoustic/optical alarm on limit exceedance. The multilogger is ready to use immediately – Plug & Play for probes and thermocouples.

The multilogger is maintenance-free, long-term stable, and equipped with a traceable calibration certificate (EN ISO/IEC 17025) – highest quality for GMP, ISO, and audits. Battery life up to several months (depending on configuration) or permanent network operation via Ethernet. Whether as a stationary logger in a control cabinet with network connection or as a portable device with battery – the M1220 offers maximum flexibility and reliability. The combination of 2× T+RH and 2× TC allows mixed operation – ideal for complex measurement tasks with room climate and process temperature.
