Review on Portable Digital Hygrometer Thermometer - Indoor Humidity and Temperature Monitor: Moisture Temperature and Humidity Sensor Gauge with Dew Point, Wet Bulb Temperature Meter Tester - Pyle PTHM20 (Red) by Chris Drury

I am an HVAC student and bought two identical meters. Both seem to give me accurate temperatures, but they differ in relative humidity by about 11%-12%. I haven't found a way yet to determine which of the two gauges is correct, but once I do I'll update this review. In the meantime, I'm only giving the meter 2 stars because I live in south Texas where we typically have high humidity, and I highly doubt that 54% RH is accurate. ***update*** I did a salt test to see which meter was correct and my guess was right. This Pyle gauge was farther from 75% RH than the other gauge. Needless to say I am returning this meter and have changed my rating for this meter from 2 to 1 star. The temperature reading was correct, but if I can't trust the relative humidity reading, I can't trust the dew point and wet bulb temperature readings. I'm sorry, Pyle, but I gave you a chance.
