GasTiger 2000 Portable Multi-Gas Detector Complete Guide — 5-Gas Confined Space Measurement, Operation, and Field Applications (Nationwide)

GasTiger 2000 — Complete Guide to Portable 5-Gas Confined Space Safety

This article provides a comprehensive introduction to the GasTiger 2000 (GT2000) portable multi-gas detector and its application in confined space safety. The GasTiger 2000 is WANDI's flagship portable gas detector, capable of simultaneously measuring all five gases required by Korea's Occupational Safety and Health Act for confined space pre-entry assessment — in a single compact unit. It is deployed nationwide across wastewater treatment plants, septic tanks, cold storage facilities, tunnel construction sites, and industrial facilities of all types.

GasTiger 2000 Key Specifications

5-Gas Confined Space Measurement Standards

• O₂ (Oxygen) — Below 18.0%: immediate evacuation. Above 23.5%: fire and explosion risk
• CO (Carbon Monoxide) — TWA 25 ppm. Colorless and odorless — undetectable without a meter
• H₂S (Hydrogen Sulfide) — TWA 1 ppm. Immediately life-threatening at elevated concentrations
• EX (Combustible Gas, LEL) — Keep below 10% LEL. Immediate evacuation if exceeded
• CO₂ (Carbon Dioxide) — Headache and respiratory distress above 1.5%; asphyxiation at high concentrations

Primary Application Sites for GasTiger 2000

• Pre-entry gas survey at septic tanks, manholes, and collection pits
• Personal safety equipment for wastewater treatment plant workers
• CO₂ and refrigerant leak monitoring in cold storage environments
• Hazardous gas verification in tunnel and underground construction confined zones
• Pre-entry inspection of industrial tank interiors

Advantages of the High-Performance Internal Pump

• A probe hose inserted into a manhole or septic tank opening allows safe remote gas sampling before personnel entry — without requiring anyone to enter first
• Strong sampling rate of ≥1 L/min enables accurate measurement through extended probe hoses (up to 10 m)
• Faster measurement response than diffusion-type detectors — supports rapid entry/no-entry decision-making

Frequently Asked Questions

Why is GasTiger 2000 the most widely used portable detector for confined space work in Korea?

It simultaneously satisfies five key requirements: a high-performance internal sampling pump, simultaneous four-gas measurement, a color display showing all readings at once, lightweight and compact ergonomics, and full compliance with Korea's OSHA five-gas confined space standard. In urgent situations, it delivers faster hazard assessment than any comparable instrument.

What is the correct pre-entry measurement procedure using GasTiger 2000?

① Power on and confirm normal operation → ② Insert the probe hose into the confined space and measure at upper, middle, and lower depths → ③ Confirm all five gases are within safe ranges → ④ Ventilate and re-measure → ⑤ Confirm safety and enter. Carry the detector throughout the work period for continuous monitoring inside the space.

Can GasTiger 2000 run all day on a single charge?

Yes — the rechargeable battery provides ≥8 continuous hours of operation. Confirm full charge before each work period; for extended field operations, a spare charger or backup power source is recommended.

How often should span gas calibration be performed?

Calibration every six to twelve months is the general recommendation. In demanding environments with frequent high-concentration gas exposure, calibration every three months is advisable. Span gas calibration should only be performed by qualified technicians — incorrect operation of the calibration function can cause measurement errors.

When should a fixed FIX800 be chosen over a portable GasTiger 2000?

GasTiger 2000 is the right tool for mobile confined space entry work, patrol inspections, and leak surveys where workers move between locations. FIX800 is appropriate for 24-hour continuous fixed-point monitoring at installed facilities. Deploying both provides the most complete safety management framework.
