Dual Input Hygro-Thermometer Psychrometer

Displays Humidity (10 to 90 percent RH), Dew Point Point (-90.4 to 122 degrees F /-68.0 to 49. 9 degrees C), wet bulb (-6.9 to 122 degrees F /-21.6 to 49.9 degrees C), air temperature (-4 to 122 degrees F /-20 to 50 degrees C) and Type K Temperature (-328 to 2498 degrees F /-200 to 1370 degrees C). Triple backlit LCD can be changed to display Humidity and Air Temperature with either Dew Point, Wet Bulb or Type K Temperature. Differential function displays the temperature differences between T1- T2, Air-T1 and T1-Dew Point. Advanced features include built-in memory to store/recall up to 99 data points, Min/MAX/Average readings from the captured data, data hold and selectable auto power off. The built-in RS232 interface (optional RS232 cable 589250) uses 407752 software to download data to a PC for storage and further analysis. Includes two general-purpose Type K temperature bead probes, four AAA batteries, and user manual.

Hygro-Thermometer Psychrometer

Simultaneously displays relative humidity (10 to 90 percent RH), air temperature (-4 to 122 degrees F /-20 to 50 degrees C) and dew point (-90.4 to 122 degrees F /-68.0 to 49. 9 degrees C) or wet bulb (-6.9 to 122 degrees F /-21.6 to 49.9 degrees C). Calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe (TP890), and T2 minus dew point. Compact meter is ideal for field applications. Unique sensor cap closes to protect to protect meter during storage. Advanced features include data hold, selectable auto power off and MAX/MIN/Average reading. Model RH305 includes the RH300, TP890 external temperature probe, RH300-CAL calibration bottles, two AAA batteries, carrying case, and user manual.

Hygro-Thermometer Psychrometer Kit

Model RH300 Hygro-Thermometer Psychrometer can simultaneously display Relative Humidity (10 to 90 percent RH), air temperature (-4 to 122 degrees F /-20 to 50 degrees C) and dew point (-90.4 to 122 degrees F /-68.0 to 49. 9 degrees C) or wet bulb (-6.9 to 122 degrees F /-21.6 to 49.9 degrees C). Calculates T1-T2 differential (air temperature minus external probe temperature) using the included external probe (TP890), and T2 minus dew point. Compact meter is ideal for field applications. Unique sensor cap closes to protect to protect meter during storage. Advanced features include data hold, selectable auto power off and MAX/MIN/Average reading. A built-in utility allows for field calibrations using the included RH300-CAL kit with 33 percent and 75 percent RH calibration bottles. The kit come complete with Model RH300, TP890 external temperature probe, RH300-CAL calibration bottles, two AAA batteries, carrying case, and user manual.
