Order # HT-WD-A, Wet/Dry Bulb Psychrometer
Base Price $500.00
Aspirated with built-in fan
Reflects solar radiation
Our wet and dry bulb psychrometer has been designed for mushroom and greenhouse applications. Wet and dry bulb humidity measurements taken with this instrument are extremely accurate because we use matched pairs of sensors and provide forced ventilation across the wet bulb using a miniature fan.
This psychrometer functions throughout the complete humidity range including the area between 90 and 100%rH where mushroom growers especially need precise control.
The outside of the unit is white to reflect solar radiation and the sensors are mounted inside the instrument so that sunshine cannot reach them.
The large water reservoir typically requires filling only once a month in high humidity areas. At low humidities more frequent filling may be required.
The fan and both temperature sensors are connected at a terminal strip inside the moisture resistant junction box on the top of the instrument.
The unit is splashwater resistant and usually suspended by the two eyelets on the top of the unit.
Because the fan will require replacement from time to time the fan assembly can be removed with one screw for easy access to the fan.
