Ryan's latest dual sensor supply portable carbon dioxide gas detector

Jinan Ryan Electronics Co., Ltd. is set Branch, industrial and trade as one integrated company, mainly produces gas detection alarm equipment, portable carbon dioxide detector professional manufacturers. Gas alarm by detecting gas can be divided, combustible gas alarm, toxic gas alarm and composite gas alarm; According to the shape can be divided into portable and fixed gas alarm gas alarm. RBBJ-T20 portable carbon dioxide detector using the LCD display, can be visualized on-site gas concentration, fast response, easy operation, long standby time, for gas, refrigeration and other industries of gas leak detection. The main features of the digitizing module design ◆ High-speed CPU processing, automatic failure identification, automatic alarm, automatic protection of high concentration overrun. High accuracy ◆ sensor using imported gas sensors, high precision, high reliability, gas selectivity, anti-interference ability and other characteristics. ◆ low power devices to monitor the status of working time ≥15 hours ◆ LCD display with LCD screen display, full Chinese menu operation. ◆ long battery life high-performance rechargeable lithium battery, a charging protection and low voltage protection features to ensure reliable battery, long life.
