Feel relaxed monitoring your colony's temperatures with these accurate thermometers. The probe is waterproof and can even be used to monitor water temperatures. Just place the probe in the area you want to read. These are perfect to monitor temperatures in very humid conditions like for leaf cutters. I personally use these to monitor my leafcutter setup temperature as they work great in very humid conditions.
