PCE-HGP humidity detector
for relative humidity and temperature as well as absolute humidity of wood and other materials (dew point in a diagram)

The PCE-HGP humidity detector is designed for use by professionals measuring climactic conditions and in the evaluation of damage in the construction industry. The humidity detector also measures relative humidity and ambient temperature as well as absolute humidity in materials and wood. By way of a table, the device can determine dew point. With this humidity detector you acquire a multi- functional device which is highly accurate for measurements to be made in situ. Other advantages are that it is easy to use, its light-weight and small. You can arrive with the device in your jacket pocket, ready to work. Remove the protective front cover, connect the device, press the two buttons at the same time, then select the measurement function and then begin measuring. This link shows and overview of each humidity detector we have available to suit your needs.

The humidity detector has some penetrating pins to capture a reading of the absolute humidity in wood or construction materials, and a combined sensor to measure relative humidity and temperature. The part of the device that measures absolute humidity is not subjected to variation with use and is reliable over an extended period. Of course, the accuracy of the relative humidity sensor will be affected over time and should be calibrated regularly. This can be done by the technicians at PCE Group or any other accredited laboratory.

For measuring relative humidity, the humidity detector comes with a humidity sensor that works in a capacitive mode, based on the reversible absorption of vapour (using a polymer lid). The apparent constant dielectric of this lid, is considered as the capacity of the device, is in direct proportional equilibrium with ambient relative humidity. The sensor is situated under the vent at the back.

The image to the left shows a humidity detector measuring the humidity of a wall (absolute humidity in % / here the reading is 9.9%). The measurement is done via two measurement pins.
The two pins are very small and once they are removed from the material, no real marks remain in the material surface that are identifiable. A measurement of absolute humidity in wood can be done with penetrating pins. If measurements of very hard materials are required, it is recommended that two nails be put into the material then the detector should be attached after they are in place.

The LCD is 15mm high and clearly shows readings. To the left of the display are buttons used for setting measurement parameters (Building Moisture for measuring construction materials, Wood Moisture for measuring wood and settings for measuring relative humidity and temperature).

General specifications

Contents
PCE-HGP humidity detectors (with standard pins), battery; 2 nails for very hard materials, protective hood and user's manual

Optional accessories
ISO laboratory calibration certificate
For companies that wish to incorporate the device into their array of internal quality control tools or for annual recalibrations. The ISO certificate includes a calibration and a document containing all the readings taken as well as containing the company details.

Replacement pins
The humidity detector comes with a series of pins placed on the end to penetrate the material. These pins may break on occasion and replacements are available in packs of ten.
Unscrew the device and change the broken pin for a new one. refasten the device and continue taking readings.
