Got 2 of these. The temperature is spot on on both and very accurate. The relative humidity is 2% different: one is spot on and the other is 2% higher-still within the 5% specification after a salt test. Bottom line: happy to own them. The company (Tech Instrumentation) is excellent in terms of courtesy, communication, price competitiveness, item packaging and shipping speed. Will do business with again!
