I came to many other unsuccessfully tried and again returned radio thermometers on this and use it since May of this year with a wireless outdoor sensor with 2m cable sensor on my koi pond. I must say, first class - data in 9 different, adjustable intervals werden- (1 min 6 h) stored and connect to the software available on the website of the company read with Exel and evaluated as a diagram. The data logger will store up to 50000 records. In addition to 8 channels (temperature and humidity transmitter or temperature transmitter with 2 m cable probe) appears, even with individual name assignment, and be evaluated. So I bought last week still 2 transmitters to zBdiesen winter the air temperature at the pool to record the temperature at 5 cm and 190 cm in depth and then evaluate on Exel.
