Elitech GSP-6Pro Bluetooth Temperature and Humidity Data Logger Recorder with Calibration Certificate, 100000 Points, Shadow Data

This is the second device I have purchased from Elitech after previously using the more basic model RC-5 extensively in domestic and business capacities.
The first one was used to record the trend of room temperatures in a children's day nursery during daytime occupation.
The GSP-6 Pro model has been used to log temperatures of a hot water storeage tank to monitor the effect of 'control set points' and did the job admirably.
I find that the devices are quality made and represent very good value - the design lends itself to incorporation into equipment designed for domestic a commercial products.
