GasTiger 2000 VOC Detector Delivery — Indoor Air Quality and Construction Site Application (Seoul)

GasTiger 2000 VOC (TVOC) Detector — Indoor Air Quality and Construction Site Application (Seoul)

This delivery case covers a VOC (Volatile Organic Compound) detector for indoor air quality management, sick building syndrome assessment, and construction site painting and urethane work environments.

What Is TVOC?

TVOC (Total Volatile Organic Compounds) is the collective term for volatile organic compounds emitted from building materials, paints, urethane coatings, adhesives, and vehicle exhaust. Key components include formaldehyde, benzene, toluene, and xylene — all classified as hazardous substances with regulated exposure limits.

GasTiger 2000 — Real-Time TVOC Measurement

The GasTiger 2000 measures TVOC concentration in real time. The standard kit includes a carry case, user manual, and all accessories required for basic operation — no additional options needed.

Air is drawn in through the inlet at the top of the unit via a built-in pump. Detected VOC concentrations are displayed numerically, and audible and visual alarms activate when readings exceed the user-configured threshold.

Delivery Site — Construction Site Urethane and Paint Work

This delivery was for a construction site. VOCs are generated during indoor urethane coating and painting operations, and the detector was purchased to protect worker safety during these tasks.

Pre-Delivery Function Test

A pre-delivery test was conducted. With windows open and clean outdoor air sampled, the TVOC reading dropped to 0 ppm.

When the probe was brought close to an open paint can, the TVOC concentration rose immediately — confirming proper sensor response before delivery.

PID Sensor — Sub-1 ppm Precision

While consumer-grade VOC meters are widely available, the GasTiger 2000 uses a PID (Photo-Ionization Detector) sensor, enabling precise measurement of VOC concentrations below 1 ppm — the level of accuracy required for professional industrial safety monitoring.

Frequently Asked Questions

Q1. Why is VOC monitoring necessary at construction sites?

Indoor urethane application, painting, and adhesive work generate large quantities of hazardous VOCs including benzene, toluene, and xylene. In enclosed spaces, high-concentration exposure causes headaches, dizziness, and nausea — and carries long-term carcinogenic risk. Real-time monitoring is essential for worker protection during these operations.

Q2. What is the difference between a PID sensor and a MOS (semiconductor) sensor?

PID sensors use ultraviolet light to ionize VOC molecules, enabling precise measurement at sub-ppm concentrations. Consumer-grade MOS sensors are sensitive but lack quantitative accuracy — they indicate presence but cannot reliably measure concentration. Industrial safety applications require PID-level precision.

Q3. How does TVOC measurement differ from individual VOC component analysis?

TVOC represents the total combined concentration of all volatile organic compounds, expressed in ppm or ppb. Identifying and quantifying individual components (benzene, toluene, etc.) requires gas chromatography (GC) analysis. The GasTiger 2000 measures TVOC total in real time, enabling immediate field assessment of hazard levels.

Q4. Can the same instrument be used for sick building syndrome assessment?

Yes. The primary VOCs associated with sick building syndrome — formaldehyde, benzene, toluene — are all detectable by a PID sensor. However, PID sensitivity to formaldehyde is lower than for other VOCs; for dedicated formaldehyde measurement, a model fitted with an electrochemical HCHO sensor provides greater accuracy.

Q5. How are alarm thresholds configured?

First and second-stage alarm thresholds (in ppm) are set directly in the GasTiger 2000 menu. When measured TVOC exceeds the configured level, audible and visual alarms activate automatically. Thresholds should be set according to OSHA regulatory limits or site-specific management standards.
