Product Description:
Model BT-B20-E Portable Flammable Gas Detector adopts advanced high-precision gas sensor technology, supporting dual-range detection for single gas, including low-concentration micro-leakage detection and lower explosive limit concentration detection. Equipped with LCD screen for intuitive on-site gas concentration display, it features fast response, simple operation and long standby time. It is ideal for pipeline inspection and household gas safety inspection.
Product Features:
※ Digital module design: Equipped with high-speed CPU for data processing, it realizes automatic fault identification, automatic alarm and automatic protection against excessive high concentration.
※ Sensitive response: Adopts high-precision sensor with high reliability, excellent gas selectivity and strong anti-interference performance.
※ Flexible probe: 65cm flexible probe supports 360° flexible adjustment for more convenient detection.
※ Exquisite workmanship: The shell is made of ABS engineering plastic, featuring compression resistance, drop resistance and good wear resistance. Ergonomic design ensures comfortable grip.
※ Ultra-long standby time: Fully charged device can work continuously for 48 hours under normal monitoring state.
