<p>Humidity sensors are used to provide an indication of the moisture levels in the environment and are very useful for industry processes. The HIH-4000 series sensors are designed with instrumentation-quality RH (Relative Humidity) sensing performance. These sensors have near linear voltage output which provides direct input to a controller or other devices. They are used in a variety of applications such as refrigeration equipment, HVAC equipment, medical equipment, drying, meteorology, battery-powered systems, and OEM assemblies.</p> <p>HIH-4000-001 Analog Humidity Sensor is chemically resistant and features laser-trimmed interchangeability. This Honeywell sensor comes with molded thermoset plastic housing and fast response time.</p>
