This is the second time I have bought this thermistor probe. The first one I bought was damaged when moving my lab equipment. The tip is about 1/8" in diameter and about 3/4" long, smaller compared to other gauges I've looked at online. I use it to control the body temperature of rats (rectally). The 1/8" plug fits securely into my thermostat. Very happy with this sensor. Also, it was delivered within a day or two of ordering (my other paper mail.) Happy customer here, thanks!
