ACI A/20K-PO-4" : 4" Probe Temperature Sensor, 20K Thermistor, 14" Etched Teflon Leads, Made in USA, 5-Year Warranty
The ACI Thermistor Probe Only Series includes a ¼” diameter stainless steel probe with two Etched Teflon-colored lead wires, distinguishing different NTC sensor types. Each sensor in this series is manufactured with ACI's reliable double encapsulation method, protecting against moisture and enhancing thermal response with high-quality, thermally conductive epoxy. The probe is intended for use in duct and immersion applications when paired with the appropriate thermowell length.
Applications:
- Roof Top Units
- Air Handlers
- Supply/Discharge Air
- Return/Mixed/Exhaust Air Duct Temperature Sensing
- Immersion Temperature Sensors
- Replacement Temperature Sensors
