Wescor HR-33T Soil Psychrometer













Wescor HR-33T Soil Psychrometer with C-52 & C-30 Sample Chambers, PST & More

The gold reference standard in soil psychrometry, a Wescor HR-33T Dew Point Microvoltmeter in excellent condition, complete with an array of sample chambers, sensors and accessories - much more than is shown in the pictures. 

Wescor's model HR-33T, can determine water potential using both dew point and wet bulb methods. It contains sophisticated sensing and control circuitry that automatically maintains the temperature of the thermocouple junction at the dew point temperature when operating in the dew point mode. 

The HR-33T can be used in both a laboratory and a field environment. Have a close look at the pictures - this HR-33T is in excellent, rarely-found condition. Major functions were tested and work very well, see photo of C-52 chamber in action.  The chambers/sensors are all in excellent or new-in-box unused condition, all listed below have been tested and are functional. All thermocouples tested were verified by both the HR-33T and by microscope (see my other auctions for microscopes). This HR-33T is the newer version that has the SUREFAST sensor quick-connect system, and all the sample chambers and sensors have this matching SUREFAST connector. This Wescor HR-33T set includes:
