Medical grade high quality NTC thermistor, 0.1 degree celsius
FEATURES:
1. Higher reliability and safety
2. Excellent thermal cycle endurance
3. Tolerance of both chips up to ± 0.1°C
4. Parallel connection provides two circuit measuring channels
Mutually tolerance checked and can prevent the circuit measuring from losing efficacy. (the one circuit still works when the other loses efficacy.)
APPLICATION:
1. Skine/ coelom / body temperature measurement
2. Esophageal / rectal / air/ skin chemical sterilisation
3. Disposal or reusable temperature probe for medical application
