WetBoss 100 - Relative Humidity Transmitter

WetBoss 100 RH Sensor -- Sensing humidity may seem easy, reflecting back on the original horsehairs and the like, but indeed, precise monitoring of RH is anything but easy. There is a fair amount of snake-oil in the industry, i.e. specs boasting of 0-100% ranges, knowing full well that the very low and very high ends are only estimates, and shrouded by the 5% FS tolerance. The mysique deepens when one discovers the virtual impossibility of reliably field recalibrating an RH sensor. Recognizing that the only way to assure continued accuracy, Rel-Tek engineered a field replaceable sensor head that can be simply plugged in without having to recalbrate the unit. In essence, the factory calibration follows the head, not the base unit. We make no bones about it, our unit is dependable between 5-95%. And, we can assure continued accuracy throughout the entire life of the product.

Thus, the WetBoss 100 has evolved over a dozen years into an honest, dependable, quality product that does the job without a wimper. Every year or so you can replace the sensing head -- a five minute job -- returning the sensor to its factory new calibration. Powered by 12-30VDC, 4-20ma, 2-wire hookup. It is MSHA classified for hazardous methane areas. A digital meter can be purchased for front panel mounting to continuously display the RH reading in 1/2" high characters. The WetBoss 100 is US-manufactrured and serviced. Rely on Rel-Tek for the best solutions.
