GASTEC Compressed Breathing Air Measurement Kit CG-1
The GASTEC CG-1 system is engineered for simple, rapid, and simultaneous measurement of harmful impurities in compressed breathing air supplied from high-pressure cylinders or compressors. It tests for Carbon Monoxide (CO), Carbon Dioxide (CO₂), Water Vapor, and Oil Mist at the same time, ensuring SCBA compliance with international diving, firefighting, and industrial safety standards.
Measures CO, CO₂, water vapor, and oil mist at once using a multi-channel manifold.
Completely mechanical and pneumatic operation, intrinsically safe for all hazardous environments.
Verifies air purity against CGA Grade D & E, OSHA, NFPA 1500, and EN 12021 standards.
Direct-reading colorimetric tubes provide clear, verifiable results in minutes without lab delays.
Housed in an impact-resistant, weatherproof carrying case built for offshore and field duty.
Connects quickly to SCBA bottles, scuba cylinders, and high-pressure compressors via dedicated adaptors.
Attach the CG-1 pressure regulator and flow system to your compressed air cylinder or compressor manifold.
Break tips of specified GASTEC tubes (CO, CO₂, H₂O, Oil Mist) and mount them securely in the 4-port holder.
Open flow for calibrated time and read contamination levels directly from millimeter calibrated color stains.

Equalizes line flow across all four tube channels for uniform sampling volume.
Precision regulator safely throttles high-pressure tank pressure down to stable sampling levels.
Direct scale printing allows immediate on-site compliance determination against legal safety limits.
Verifies dive air purity against EN 12021 and CGA standards to protect divers from toxic gas hazards.
Ensures firefighter self-contained breathing apparatus air banks meet NFPA 1500 standards.
Validates medical air compressor feeds for zero toxic CO and low moisture content.
Conducts regular air quality audits for breathing air cascades and confined space air trailers.
Maintains strict purity compliance for flight crew oxygen and breathing systems.
Guarantees supplied-air respirator lines are free from compressor oil mist and toxic combustion gases.
Proven parameters engineered for critical breathing air verification across UAE & GCC industries.
simultaneous measurement saves over 80% testing time compared to single-tube systems
intrinsically safe design requires no battery charging or calibration electricity
fully certified to comply with international breathing air purity thresholds
