Features:1. New design in 2021, built-in imported high-precision sensor chip, the detection accuracy of ±0.005% BAC is comparable to professional instruments, and the detection range of 0.00-0.19% BAC (0-1.9G/L) is also very wide.2. The non-contact detector is safer, the product is designed with a gas receiving hole, Non-contact blowing detection. The blowing time of 4 seconds is very fast.
