Review on π¬ FORENSICS O2 Detector: NIST Calibration & Certificate, Dust & Explosion Proof, USB Rechargeable, Sound/Light/Vibration Alarms, 0-30% Oxygen by Non Martin
very bad product support.
Calibration information was very confusing. Information about the battery for charging was also incomplete. This is the first time I've been disappointed with the things I've bought from Amazon. I think I'll look for other sources for the products I buy online.
- Great price
- Minor issues
