The TH-4000 is a hand-held Humidity-Temp meter with a detachable RH/Temp sensor probe and Dew Point Display Function.
This meter measures Relative Humidity of enclosed environments such as museums, libraries, server rooms, calibration laboratories, warehouses, etc. for monitoring and controlling purposes.
The TH-4000 has a measuring range of 10 to 95% RH and 0°C to 80°C.
The TH-4000 has a large LCD display which clearly shows measured RH and Other features of the meter include Data Hold, Data record of Max/Min values.
Data can be recorded into a PC via the built-in RS232C serial interface. CE and RoHS compliant.
