Product description
K-100A H2S/CO/EX/O2/NH3 Single Gas Detector Ensures Worker Safety at All Times 
K100A portable single gas detector can make continuous detection to combustible and toxic gases. It is suitable for combustible and toxic gas leakage detection in underground pipe or mines, and keeps the workers safe, prevents the facilities from being destroyed.
Visual, Audible and Toctile Alarms – Never Miss Danger! 
Engineered for OSHA/NFPA compliance: Triple-sensory alerts ensure zero missed threats. Audible alarms cut through high-noise zones, strobes penetrate darkness, and vibrations alert through heavy clothing/PPE. Hazard recognition and prevent exposure incidents. Meeting 29 CFR 1910.119 requirements.
Customizable Alarm Thresholds Enable Site-Specific Hazard Response 
Set High/Low alerts for exact PEL/STEL compliance monitoring. Prevents false alarms in variable-background environments while ensuring critical IDLH warnings. Validates instrument alignment with 29 CFR 1910.1200 Hazard Communication Program requirements.
User Friendly – Low Battery Reminder 
Low batterry reminder ensures timely charging before critical safety function loss. Mitigates undetected hazard risks during confined space entries or extended monitoring per 29 CFR 1910.134 compliance requirements. Ensures instrument reliability throughout work shifts.
Manual Calibration to Ensure Traceable Accuracy 
Perform on-site zero & span adjustments per 29 CFR 1910.146. Corrects sensor drift, compensates for environmental variables, and maintains OSHA-compliant precision.Validates instrument reliability before critical deployments, preventing false alarms/undetected hazards through verifiable performance.
