Cleaning air in enclosed spaces is a major priority in schools, with more districts, colleges, and universities bringing students back from virtual lessons and into the classroom. That makes your job tough. What’s tougher? IAQ projects that have stalled because suppliers don’t have product and can’t meet your deadlines to get these important air quality projects done. That won’t happen with Dwyer. We have sensors, gages, and monitors in stock and ready to meet—and exceed—your needs. That way you can complete your punch list and help students, faculty, staff, and visitors breathe easier.


Series RHP-N Humidity/Temperature/Dew Point Transmitters

The Series RHP-E/N Wall Mount Humidity/Temperature/Dew Point Transmitter is the most versatile room transmitter on the market. The stylish housing is well vented to provide air flow across the sensor to improve measurement accuracy. The humidity and the dew point are measured using a capacitive polymer sensor that completely recovers from 100% saturation. The humidity and dew point can have either a current or voltage output, while the optional temperature output can be a current, voltage, RTD or thermistor.
