Temperature data logger with two temperature sensors

The LGR46 is available with an external probe with two measuring points, each of which have accuracy of ±0.3°C. The measurements are transmitted directly to a PC, where they are then displayed. The measurement data is transmitted live by radio to the monitoring workstation, or is stored in the data logger until it is called up wirelessly. This device was especially developed for heating engineers and for monitoring hot water installations.

The STT51-003 probe can be connected directly to the LGR46, and was specially developed for heating engineers and also for monitoring hot water installations. It comprises 2 temperature probes, which can be connected to different pipes.



Product references:
