Review on 🎯 Enhanced Accuracy of Supco IAQ55 Handheld Resolution by Raymond Iglesias

Decent product. The relative humidity was far away. Luckily I have a relative humidity calibration kit from a similar device from another company (same monitor, different company name). I used this to calibrate rh. CO2 and temperature are normal. It's hard to beat the price. It was cheaper to buy this device than to send the previous one to be calibrated. Find out.
