The HP125 Series from Edgetech Instruments Inc. is a precision probe designed for simultaneous measurement of relative humidity, temperature, pressure, and calculated dew/frost point temperature. It features a rugged capacitive humidity sensor and is resistant to most chemicals, making it suitable for various industrial applications such as HVAC, environmental chambers, and compressed air systems. The operating temperature range is -40¬8C to 125¬8C, ensuring reliable performance in extreme conditions. The HP125 maintains an accuracy of ¬±1.8% for relative humidity and ¬±0.5¬8C for temperature, with a dew/frost point accuracy of ¬±1¬8C from -10¬8C to 95¬8C. The probe includes a field-replaceable Smart Sensor Tip, allowing for easy on-site sensor replacement without the need for extensive downtime or factory calibration. It also offers 0-10 Vdc analog outputs and an optional remote display module for enhanced monitoring capabilities. With a life expectancy exceeding five years and a compact design, the HP125 is a versatile solution for engineers seeking reliable and accurate environmental measurements.
The HP125 Multi-Sense Humidity Probe is a cost effective, easy to use solution to many industrial and laboratory measurement and control applications. The HP125 probe exploits the latest advancements in polymer humidity sensing technology and compact electronic circuitry. It is designed to continuously measure up to 4 measurement parameters using a single intelligent sensor tip including RH%, calculated Dew Point, Temperature and either Absolute Pressure or Barometric Pressure!
The Smart Sensor Tip carries all configuration information and calibration data and automatically downloads to the HP probe once connected! Easily replaced, 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 0-10VDC analog voltage outputs plus an RS-232 serial interface. The RS-232 offers reporting functions only. Each probe is configured with a smart sensor tip. 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
The probe may be used Stand-Alone or in combination with the HP125-DCM (Display Control Module) or the SENTRY series of Compressed Gas Alarm Modules. The probe comes with wire leads (labeled) for respective analog output and power inputs (25VDC Power).
