The TM-200 is a self-contained skin surface temperature transducer
(thermistor) with a range of 25 degrees C to 45 degrees C at an accuracy
of +/-0.1 degrees. The sensor is a rugged epoxy-sealed disc measuring
12 mm in diameter by 4 mm thick. The TM-200 requires a transducer
conditioning amplifier such as the ETH-256 or ETH-401, or an iWorx
computer interface equipped with transducer inputs.
