Review on 🔬 Forensics Multigas 4 Gas Monitor: Color Display, Graphing, Data Logging, USA NIST Calibration, USB Rechargeable Battery by Jaie Bobin

My normal device failed in the field and I bought this device with overnight delivery. I opened the box and found a well built device, easy to use, calibrated (with certificate) and ready to charge. I used it the next day and I heard I had to tell you about it so it must have worked or at least I was in a safe area and made sure it was safe thanks to this product is. The only negative thing I could say is that the screen was hard to read in direct sunlight, but in my swamp and indoors I was able to read it with ease. Thanks to this product I was able to complete my work. Karl
