Digital Humidity meters This large dual display temperature and humidity unit offers two temperatures, internal and external, humidity and stores the maximum and minimum of each sensor. Can be wall mounted or stand alone, runs on internal battery. Large LCD display makes for easy readability. Ideal where are quick display of humidity and temperature is needed without calculating wet and dry bulbs. A unique feature of digital instruments over spirit thermometer or dial hygrometers is the ability to store maximum and minimum humidity information.
Features data hold key and voltage output for remote indicator or recorder.
The remote probe is ideal for use in ducting or other HVAC applications. Also available but not illustrated is the General Eastern precision thermohygrometer with NIST traceablity and individually calibrated sensors to maintain traceability. The sensors are permanantly affected by many common solvents. Also moisture condensing on the sensors can take several days to evaporate and will cause false readings.
