The RH511 is a low cost, high performance, handheld
temperature/relative humidity/infrared meter. This meter
has many features including two temperature inputs (Type K
thermocouple), triple LCD display of humidity/temperature or
infrared temperature and thermocouple temperature, MIN/
MAX/HOLD functions, data logging, USB interface with
Windows based PC software, and wireless temperature/
humidity sensor probe option.
