COMET Logger U0121 - temperature two channel; 2x Pt1000 input

U0121 Two-channel thermometer for external probes
This model can measure one, two or 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. The battery in the device cannot be charged.
