The HP125 Multi-Sense Probe is a cost effective, easy to use solution to many industrial and laboratory measurement and control applications. It continuously measures up to four parameters including percent relative humidity, dew/frost point, temperature and absolute or barometric pressure using a single intelligent sensor tip.

The HP125’s Smart Sensor Tip carries all configuration information and calibration data, and automatically downloads to the HP probe once connected. The Smart Sensor Tip can be replaced in seconds. Upon installation into the probe, it gets recognized and automatically synchronizes with the main software within the HP125 probe. This means that you have the option of quick turn-around for annual calibrations. No need to take the probe out of service for weeks for shipment and calibration off-site. Simply replace the old Sensor Tip with a new one. Each new tip comes with a NIST traceable calibration certificate for your records.

The HP125 probe provides 0 to 10 Vdc analog voltage outputs plus an RS-232 serial interface for reporting functions. The Sensor Tip is protected by a sintered metal filter cartridge. Both the filter and the sensor tip are replaceable. The probe may be directly inserted into process measurement points or may be coupled with a variety of application-oriented sampling accessories for very flexible installation opportunities.

The probe may be used as a stand-alone device or in combination with the HP125-DCM (Display Control Module) or the SENTRY series of compressed gas alarm modules. The probe comes complete and ready to install.
