Thermocouple LOG87-001

with housingwall-mountwireless

Overview
The LOG87 is a temperature and humidity sensor designed for real-time monitoring and data logging. It measures temperature and relative humidity with high accuracy and stores measurements with date and time in internal memory.

Operating modes

• Monitoring mode: measurements are sent in real time to a receiver for continuous monitoring. If a measurement is not received by the receiver (for example: receiver key not plugged in, PC switched off, RF‑Monitor not running, communication problem), the data logger records the measurement in its buffer memory. As soon as communication is restored, buffered measurements are automatically transmitted to the PC.
