In the early 1960s, in the U.S. state of Oregon, Delmer Wagner designed one of the first solid state, non-contact, in-line lumber moisture detectors. Not long after, customers started asking the pioneering inventor to develop hand-held moisture content test meters for use in spot checks. This was how it all began for Wagner Meters, which went on to produce a whole range of devices for testing and measuring the moisture content of wood and the relative humidity of concrete over the following decades. Despite enjoying major business success, Wagner Meters has resisted the temptation to outsource its production to countries offering cheaper labor. And Ed Wagner, Delmer’s son, is determined to ensure Wagner Meters remains an American employer with global reach.

This year, the company's reach is extending all the way to Hannover, to DOMOTEX 2020, where it is showcasing various innovations, including its Rapid RH L6 Smart Sensors. Using CMOSens technology, these sensors are factory-calibrated to provide accurate readings right from the get-go. In fact, to put users' minds at ease, each Smart Sensor kit comes in tamper-resistant packaging and with a calibration certificate. What's more, every Rapid RH L6 sensor features a customized version of the SHT35 humidity sensor from Sensirion, which takes measurements with a +/-2 percent accuracy tolerance at 50 percent and 90 percent relative humidity. This key aspect ensures the RH testing system adheres to the ASTM F2170 standard and sets it apart from conventional SHT35 humidity sensors, which deviate considerably from the two-percent tolerance at relative humidity levels as low as 50 percent.
