PCE-320 psychrometer
measures humidity, temperature, dew point,
wet bulb globe temperature and surface temperature

The PCE-320 psycrometer is an exceptional product at such a low price. With the PCE-320 psychrometer it is possible to measure climate conditions such as temperature and relative humidity as well as to determine the surface temperature of objects simultaneously by using an external temperature sensor (included in the delivery) or an infrared measurement. The PCE-320 psychrometer provides additional information relating to dew point (dew point temperature) and the global humidity temperature. Measurement values can be directly seen on the device's display; maximum and minimum values can be registered or transfer to a PC or portable computer for further analysis. It will allow for the prevention of fungus in food when being stored and during transportation. The PCE-320 psychrometer is also very useful in the construction industry. Customers frequently complain about not having a tool available that can measure ambient conditions and surface temperature of a wall both inside and outside. The PCE-320 psychrometer can also be used in the industrial sector and in product development. The device can either be verified in situ using an optional calibration kit or it can be sent away to be calibrated by an accreditted DIN ISO laboratory. We offer the possibility of ISO calibration from factory (when the device is ordered or as an annual recalibration). Here is another psychrometer that can also determine dew point and global humidity temperature.

Examples of use of the PCE-320 psychrometer

The upper image shows the PCE-320 psychrometer measuring normal ambient conditions in a room (temperature and relative humidity). With this data it is possible to calculate dew point.
Also, you can see the PCE-320 psychrometer measuring the temperature of a wall.  We can see that the temperature of the wall is below the dew point. When this occurs, humidity forms inside the wall. This is the same measurement that is taken inside storage refrigerators or products that are being transported great distances. As you can see, the range of applications for the psychrometer is extensive.

Delivery contents
PCE-320 psychrometer, 1 external temperature sensor (1m long hot wire sensor, up to 200°C), software and data cable, 1x 9V battery and user's manual

Optional accessories
- Type-K thermal elements / Temperature sensors
Here you will find a wide selection of type-K external temperature sensors that can be used with the psychrometer, including surface temperature sensors or high temperature sensors.

- Humidity calibration kit
In order to independantly calibrate the PCE-320. The kit is composed of two humidity standards (33 and 75% r.h.).
Simply place the sensor in the standards and press a button.

- ISO laboratory calibration certificate
For companies that wish to incorporate the device into their array of internal quality control tools or for annual recalibrations (if not using the calibraton kit). The ISO certificate includes a calibration and a document containing all the readings taken.
