This portable dew point hygrometer integrates the accuracy and reliability of the OMEGA™ chilled mirror with the battery life and ruggedness required for field use. The RHB-1500-C portable chilledmirror hygrometer has all the standard features, such as drift-free NIST-traceable accuracy, low maintenance, high durability, and ease of use—in a system that is ideally suited for the demands of field use. Whether you use the RHB-1500-C as a field transfer standard or to spot-check your process air dryness or dew point, you'll find this system provides trouble-free operation. The RHB-1500-C is a self-contained system. Not only is no field assembly required, but also there's no need to carry around a myriad of individual components such as control boxes, sensors, cables, pumps, and power cords. Simply attach the sample line, adjust the flow (with the integral flowmeter), and turn on the power. Within minutes you'll be collecting field dew point data with the same chilled-mirror accuracy of a lab-standard hygrometer. And with a nominal battery life of 12 hours, the RHB-1500-C lets you collect for the entire shift or spot-check your processes for several days.
