COMET Logger U0141M - GSM temperature, humidity, CO2 and atmospheric pressure data logger with built-in sensors and modem

U0141M - GSM Temperature data logger for four external probes with built-in modem
This model can measure up to four temperature values transmitted by Pt1000/E series external probes. The response to a temperature jump depends on the connected probe design. As a rule, this model is few times faster than that using the inner sensor. It is often used to monitor locations where the device itself is not directly in the measuring space and only probes are in. The maximum length of each probe lead should not exceed 15 m. It is recommended to use shielded cables. To maintain the IP rating, the unused probe connectors should be provided with a supplied closing cap.
