Medical Thermistor, 400 Series Thermistors

The 400 Series-type 2252 ohm thermistor is recognized world-wide as the de facto standard for patient monitoring applications. Compatibility with all OEM monitoring equipment accepting the 400 Series thermistor is assured. To supplement the standard Molex termination, Sensor Scientific has developed an easy-grip molded connector to improve contact reliability in critical applications. The optional .070” maximum diameter tip allows for easier insertion into smaller size catheter assemblies.
