Temperature Data Logger for Two External Pt1000 Probes
Datalogger is designed to record temperature from two external Pt1000 probes. The recording is performed in non-volatile electronic memory.
The data can be transferred to a PC via USB-C. In case of exceeded set limits alarms are indicated by LED, LCD, and acoustically by built-in beeper.
The device includes a Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of EN ISO/IEC 17025 standard.
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 a 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.
