Water proof humidity sensor has proven to be duriable through daily room wash downs when used in food processing plants. It is field adjustable so it can be calibrated monthly, yearly, etc. This 4-20ma transmitter can be used with a LCD display to verify if room humidity is within specs.

My Favorite Feature Ease of replacing and calibrating

Pros: Good value, Always in stock

Yes, I recommend this product.
