KMK - 600 4 in 1 Underground Facility Gas Sentinel
Introduction
Underground Facility Gas Sentinel: KMK - 600 is designed specifically for workers in underground facilities such as sewers, underground storage tanks. Using gas pump sampling, it quickly detects various gases with an accuracy of ≤±5% F.S. within 30 seconds. The device features high - strength, waterproof, dustproof, and explosion - proof housing. It operates on a DC3.7V lithium battery for over 8 hours, providing continuous protection in underground and potentially dangerous environments.
