Johnson Controls HE-69530NP-0 Duct Humidity & Temperature Sensor 3% RH Accuracy, 1k Ohm

The Johnson Controls HE-69530NP-0 is a high-quality instrument that serves to measure humidity and temperature in HVAC ducting with a lot of precision. The power electrical circuit consists of a platinum temperature sensor with 1K ohms that gives a 0-10 VDC signal to HVAC controllers. This is a small, blue plastic housed sensor designed for duct mount which is accurate with a 3-percent relative humidity range. Running on a normal 24 VAC/VDC power supply, it is an energy efficient device that synchronously performs optimally.
