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 HT-WD-420 transmitter is a microprocessor based device that uses the signal from two 3-wire RTD sensors (wet bulb and dry bulb) to calculate the relative humidity value. The microprocessor utilizes a scientific rH calculation algorithm that produces very accurate data over a wide temperature range. (This algorithm is a refined version of ASHRAE equations used originally for the creation of Psychrometric Charts)
The board may be programmed for various above sea level values to allow rH compensation in the wet/dry method. The output is linear in its entire range from 0 ...
These humidity transmitters are the type used on unattended remote weather stations across Canada. Even in arctic conditions they perform accurately and without problem. In energy management projects with hundreds of points it is normal to have only one outdoor humidity sensor. If that sensor is not accurate then energy costs may rise and building comfort may suffer. The trouble free, accurate, service year after year of these transmitters can quickly justify their higher cost.
Specially prepared human hair is used as a sensor. These hairs are specially treated to make them react quickly to changes in humidity. ...
Use our thermohygrographs whenever you need a record of humidity and temperature conditions. Just put them in place and start recording, no connections, not even a power cord. That's faster, easier and likely less expensive than electronic instrumentation and data loggers.
Because we can supply them with traceable humidity and temperature certification and these recorders are easily transported to our Toronto plant for re-certification they may be ideal to meet your QA requirements. Applications include laboratories, clean rooms, museums, libraries, warehouses, environmental chambers ...
