Model 4PHM

Four-Port Heated Manifold

4 Port Manifold w/Heat Controller Assembly

The Four-Port Heated Manifold Accessory is a commercial-off-the-shelf manifold that has four straight threaded ports. With power applied the manifold automatically controls the temperature of the manifold assembly from ambient up to 60 °C to aid in the dry down process of the frost point/dew point probes being calibrated. The manifold is equipped with a back-pressure regulator to allow the user to control the test pressure of the manifold from ambient pressure to 50 psiA if desired. The manifold supports flow rates from 1.0 to 4.0 SLPM and uses adaptable inlet and outlet fittings for connection.

APPLICATIONS

The 4PHM is designed to be used as an aid to calibrate 4 humidity sensors at the same time. This equates to a faster turn-around time for your calibrations. This means that each instrument will have the same accuracy and uncertainties. This manifold is specifically designed to be used with either the Model 3900 or the 3920 Low Humidity Generation Systems.

This manifold is used to aid in the dry down process of the frost point/dew point probes being calibrated for faster calibration times.

With this manifold you can connect Humidity Sensors to determine humidity calibration accuracy and/or characterize humidity sensitivity by subjecting the humidity sensor to a variety of humidity levels; perform operational checks such as the sensing systems capability to correctly calculate and display other humidity parameters; determine repeatability, stability, hysteresis, and drift characteristics of various humidity sensors.

Note: The specifications listed, and the information provided are subject to change without notice.
