Which models of temperature/humidity meters have remote probes?
The LRTH185DL1 and DTH3007SD have attachable remote temperature/humidity probes. The EMR963HG has a wireless, remote temperature/humidity monitor. The following models have temperature only wireless r...
Which models of temperature/humidity meters are calibrateable?
The following models have a calibration feature: EP8703, EP8706, EP8709, EP8710, LRTH185DL, LRTH185DL1, WBGT8758, WBGT8778, DTH3007SD, RHMG650, RHMG700DL
My instrument is calibrateable. Do I need any additional accessories to perform the calibration?
Some instruments do require a 33% and 75% salt bottle to perform the calibration. The following models use the HR33 and HR75 bottles: DTH3007SD, EP8703, EP8706, EP8709, EP8710, LRTH185DL, LRTH185DL1, ...
What is Dew Point?
In simple terms, the dew point (dew point temperature or dewpoint) is the temperature at which a given concentration of water vapor in air will form dew. More specifically it is a measure of atmospher...
What is Wet Bulb?
The wet-bulb temperature is the temperature a parcel of air would have if it were cooled to saturation (100% relative humidity) by the evaporation of water into it, with the latent heat being supplied...
What is a psychrometer?
A psychrometer is an instrument that measures both the wet bulb and dry bulb temperatures.
