The HS replaceable humidity element is designed to lower costs and reduce downtime. It features thin-film capacitive technology for superior accuracy and exceptional resistance to contaminants. It is compatible with all Veris deluxe sensors, making replacement quick and easy. No need to install a new humidity sensing device, just insert a new element into the unit and resume operation. These humidity elements are calibrated in a high accuracy, humidity generator. Each sensor is digitally calibrated at four different relative humidity levels over an eight-hour period. Calibration data is programmed into the replaceable sensing element. This computer-controlled digital calibration eliminates errors associated with manual trimming. The two-pressure method involves saturating air with water vapor at a given pressure and temperature. Saturated gas then flows through an expansion valve where it is isothermally reduced to chamber pressure. Gas temperature is held constant during pressure reduction, so relative humidity at chamber pressure is calculated as the ratio of two absolute pressures. Temperature uniformity in the chamber is maintained by circulating a temperature controlled fluid through a shell surrounding the test space. The resulting system accuracy is better than 0.5% RH over all ranges and temperatures. This system is capable of continuously supplying accurate humidity values for instrument calibration, evaluation, and verification.
