Extech's RH390 Precision Psychrometer allows you to measure humidity and temperature simultaneously. A dual-illuminated readout can be set to show wet bulb and humidity, dew point and humidity, or temperature and humidity. This handheld gadget monitors temperatures from -22 to 199 degrees F (-30 to 100 degrees C) and measures relative humidity with ±2% accuracy between 20 and 90% RH. Complete with a carrying case and a 9V battery.

The RH350 monitors humidity, dew point, wet bulb temperature, and temperature differential. The triple backlit LCD can be configured to show humidity, temperature, and dew point, or humidity, temperature, and wet bulb, or humidity, temperature, and Type K thermometer. Can also show the temperature difference between Type K T1 and T2, air temperature and Type K, or Type K and dew point. Advanced features include built-in memory and recall of up to 99 data points, min/max/average readings from captured data, data hold, and customizable auto power down. Includes two Type K temperature probes and four AAA batteries.

The RH300 is a small meter that is suited for field use. Simultaneously displays relative humidity (10% to 90% RH), ambient temperature, and dew point or wet bulb. Calculates T1-T2 differential (air temperature minus external probe temperature) with optional probe (TP890) and T2 minus dew point. Sensor cap with built-in protection. Additional functions include Data Hold, Auto Power Off, and MAX/MIN reading. Comes with two AAA batteries.
