Overview
Enviro Testers 4-in-1 gas detector – alarm enabled is a portable voice-type four-in-one gas detector, which is a safety device that can continuously detect the concentration of leaking gas. Using advanced integrated circuit technology, embedded microcomputer control, high-quality imported gas sensor, with excellent sensitivity and excellent repeatability, easy to use and maintain, the shell is made of high-strength engineering plastics, which has good vibration resistance, high strength, and has the functions of dustproof, waterproof and explosion-proof.
Features
- Sound, light, vibration, screen flashing quadruple alarm
- 2500 mAh built-in high-capacity lithium battery
- Automatically store records that can be viewed and deleted 2.4-inch color LCD display
- High-strength engineering plastic, anti-compression, anti-drop, explosion-proof
- Adopt imported sensor, sensitive induction, short response time, more accurate detection
- Support curve drawing, easy to observe the periodic state of gas concentration
