🎯 Enhanced Accuracy of Supco IAQ55 Handheld Resolution Review

Let's start by saying that this "supco" is not made by Supco. Even they said they just wrote the name on it and another "American" company that sells devil souls there. I called them 3 times to find out what's going on and couldn't get anything. I had had enough returns and went to my local plumbing store and bought a real one.

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.

The same product is offered by other vendors in different colors at very different prices. Note that with the expensive item you also get a 120VAC-9VDC power adapter for this product, as well as a very rare RS232 to USB converter. None of that is in the Supco product, so the price is low. A serial to USB converter cable is rare as the serial port on the monitor is not a standard 9 pin serial plug or connector but a connector similar to the audio port on your cell phone. phone or other device…
