Overview
The LGR37-001 is a temperature sensor and data logger designed for Thermocouple K probes. It supports real-time monitoring and onboard data recording. The unit is supplied in an IP65 aluminium enclosure, includes a ½-wave antenna with SMA connector and is powered by an AA Lithium Thionyl battery (plug-in connector).

Modes

• Monitoring: continuous real-time transmission of measurements to a PC. If a measurement cannot be received, it is stored locally and forwarded on the recording channel.
• Recording / retrieval: local logging of measurements with date/time; stored data can be downloaded to a PC on demand.
