Rugged, waterproof, very low temperature data logger for use with a PT1000 probe

-200 to +100°C

Requires PT1000 Probe

The TGP-4204 uses a PT1000 probe for very low temperature monitoring. PT1000 probes monitor from -200 to +100°C, making this unit a versatile solution typically for freezers and cryogenic applications.

This logger requires Tinytag Explorer software and a USB cable (CAB-0007-USB). To wire your own probe/sensor to this logger you can get the 5-Pin Plug (ACS-9703).
