Overview

The GD-02 is a reliable color-screen gas detector for methane, also tracking temperature and humidity. It delivers fast, accurate readings, quick startup, rapid zeroing, and resists low temperatures, poisoning, and interference. Durable and precise, it maintains performance for over 3 years.

Features

2.0" Full-Color TFT Display – Real-time display of gas concentration and ambient temperature/humidity with 0.5s refresh rate.
Curve Analysis & Data Recording – Supports trend curve analysis and record tracking for more intuitive monitoring.
Adjustable Brightness & Dual UI Themes – Switch between light/dark modes for day and night environments.
Multi-Gas Detection – Accurately detects methane, propane, and isobutane.
Wide Detection Range – Methane detection range of 0–50000ppm with 1ppm / 1% LEL resolution.
36cm Flexible Probe – Easily detects in complex, narrow, or hard-to-reach spaces.
Triple Alarm System – Audible, vibration, and visual alerts ensure timely safety warnings.
Alarm Record Storage – Saves up to 30 alarm records for easy tracking and review.
Fast Response & Recovery – <5s response time (T90) and <10s recovery time (T10) for rapid hazard detection.
Long Sensor Lifespan – Durable sensor with over 3 years of reliable service.
Rugged Environmental Adaptability – Operates in -10~55℃ with strong resistance to electromagnetic interference.
Lightweight & Portable Design – Weighs approx. 296g, with a built-in flashlight for low-light or emergency use.
Performance Upgrades & Data Hold – Supports USB Type-C firmware updates and data hold function for recording and analysis.

Precautions

Situations to Strictly Avoid

Condition	Risk
Exposure to volatile silicon compounds (adhesives, hairspray, silicone, etc.)	Permanent reduction of sensor sensitivity
Exposure to high concentrations of corrosive gases (H₂S, SOx, Cl₂, HCl)	Corrosion or irreversible performance degradation
Contact with alkalis, alkali metal salts, or halogens (e.g., Freon)	Performance deterioration
Sensor contact with water or submersion	Reduced sensitivity
Ice formation on sensor surface	Cracking of sensitive layer and failure
Applying voltage above specified value	Damage to leads/heater and reduced sensitivity

Situations That May Reduce Sensor Performance

Condition	Effect
Minor condensation	Minimal short-term effect
Prolonged moisture on sensor	Performance degradation
Long-term exposure to high gas concentrations	Reduced sensor performance
Direct gas spraying (e.g., lighter gas)	Severe sensor damage
Prolonged extreme humidity, temperature, or pollution	Severe performance impact
Frequent/excessive vibration (transport, pneumatic/ultrasonic assembly)	Broken internal leads

Prohibited Conditions

Prohibited Action	Consequence
Allowing liquid contact with sensor	Damage to gas-sensing function
Plugging/unplugging or disassembling sensor module	Sensor damage
Modifying or moving electronic components	Malfunction
Blocking ventilation area	Reduced sensitivity and slower response
Excessive impact or vibration	Unreliable output
Long-term exposure to high gas levels	Slow recovery proportional to overrange level
Disassembling the sensor	Permanent damage
