The Sensaphone FGD-IM28B 2.8K Immersion temperature sensor is a waterproof temperature sensor for measuring the temperature of fluids inside a pipe. It's constructed of Brass WEL-B thermowell (which screws into a customer-supplied 0.5" NPT saddle or Thredolet fitting in a pipe). It fits into a thermowell via a Brass 0.125" NPT fitting. The sensor is accurate to +/- 1F (0.56C) and has a sensing range of -40F to 175F.

Not recommended for salt water aquariums as this sensor will leech harmful metals that could kill your fish.
