**Good Quality and Competitive Price Combustible Gas Detector**
The JCB4 portable combustible gas detector is a compact, intrinsically safe, and explosion-proof device designed for monitoring flammable gases in hazardous environments. Ideal for underground coal mines, fire fighting, confined spaces, chemical industries, and oil sectors, this low-cost, maintenance-free single-gas monitor offers reliable protection against dangerous gas exposure.
Despite its small size, the JCB4 features advanced capabilities typically found in larger multi-gas detectors, including an OLED display, internal audible/visual alarms, and user-friendly push-button operation. The device continuously monitors ambient gas levels and alerts users when concentrations exceed pre-set thresholds. Additional features include adjustable alarm setpoints, calibration gas values, and a choice of text-only display.
A peak/hold function ensures users can track the highest reading during their shift, while a flip-cap calibration adapter simplifies the calibration process. The JCB4 is covered by a two-year warranty from the date of manufacture, ensuring long-term reliability and cost-effectiveness.
**Key Features:**
- **2-Year Warranty:** Reduces total ownership costs with full coverage.
- **Lightweight Design (102g):** Easy to wear on a belt, pocket, or hard hat.
- **Flip-Cap Calibration:** Built-in adapter eliminates the need for external calibration tools.
- **OLED Display:** Shows real-time gas concentration and battery life.
- **Adjustable Alarms:** Customizable for various applications.
- **High Visibility Case:** Ensures easy identification by safety personnel.
- **5-Second Delay Shut-Off:** Prevents accidental power-off.
