The TM-BIO is a self-contained temperature transducer with a range of 0 degrees C to 50 degrees C. The sensor is a rugged epoxy-sealed pellet measuring only 3.0 mm in length and 1.0mm in diameter. The small mass of the sensor gives the TM-BIO a fast response time. The sealed enclosure makes cleaning and/or sterilization easy.

The TM-BIO plugs into the Bio or GSR inputs of the IX-Bxx or the iWire-Bxx recorders.
