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,NIST traceable,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." A certificate of calibration is provided with NIST versions of the HS.
