TH30S-B Probe

Good But way too short

The probe does what it needs to do but it is only 3 meters long. The probe needs to sit behind a condenser placed at the back of a cool room while the head unit must be outside. Options for 5m & 10m would be appreciated

TH30S-B Probe

Works fine so no complaints. To be honest I bought it to enable me to use two temperature probes with a WS1-Pro

Inaccurate calibration

The temperature reading with this probe was almost exactly the same as my other sensors, but the humidity readings are 5% higher. It's disappointing that it's not calibrated correctly straight out of the box, but at least you're able to manually adjust the calibration on the web based console to compensate for the difference.
