Review on 🔍 Forensics 4 Gas Monitor with USA NIST Calibration: O2, CO, H2S, LEL, USB Rechargeable by Joshua Ngo

I am a WAP weather manager/energy auditor/QCI. We are required to carry both CO and LEL monitors when conducting inspections and energy audits. I ordered this monitor because it does both and the price was lower than the stock BW and Testo units. On my first test I took my trusty sensorcon to compare the readings, the sensorcon worked as usual but the forensics didn't. I found 2 to 5ppm CO with Sensorcon and 0ppm with Forensics. Sorry, I can't risk it with forensics. My devices must comply with WAP standards, I cannot allow the use of devices that are not 100% accurate and not calibrated. I have to be careful with my budgets and maximize them, but it looks like I'm spending more on BW monitors.
