A low relative-humidity sensor, designed for measurements in drier environments, is now available with the GE Protimeter North America MMS Plus version. The Low Range RH Sensor ensures accurate readings through the zero to 40 percent relative humidity range, the company said.

The MMS Plus is a hand-held instrument designed to detect moisture on and below surfaces, measure relative humidity/temperature and determine whether condensation is present. The sensor can be purchased as an option for the MMS Plus
