Extech's RH300 is used to carry out measurements of %RH, air temperature, dew point, wet bulb and probe temperature and can display results simultaneously on its LCD screen.
The tester can measure humidity from 10 to 90%RH, internal temperature from -4 to 122°F (-20 to 50°C), temperature (external) from -4 to 158°F (-20 to 70°C), dew point from -90.4 to 122°F (-68.0 to 49.9°C) and wet bulb from -6.9 to 122°F (-21.6 to 49.9°C). Via the use of external probe (not included) the RH300 can also be used to calculate T1-T2 differential (air temperature minus external probe temperature) and T2-dew point.
To carry out measurements the RH300 uses a unique sensor that includes a twist cap, allowing the sensor to be protected during transportation and storage. The unit also contains a few extra functions such as switchable Celsius/Fahrenheit measurements, data hold and MAX/MIN readings.
A kit version of this product also exists. The RH305 includes the RH300, a temperature probe, calibration solutions and a carry case. To view more information about this item click the link to your left.
