Portable four in one gas detector

Portable four in one gas detectorIt is a multifunctional gas detection and alarm device that integrates gas, time, air pump, alarm, recording, and data storage for continuous monitoring. The instrument uses EFM ultra-low power 32-bit GASM, and the sensor adopts high-precision sensors. The sensor part uses two-stage high-precision low-temperature drift amplifiers and highly stable power processing circuits to ensure fast detection, accurate measurement, stability, and good repeatability of the instrument. The instrument adopts a large full-color 3.5-inch TFT screen, supporting both Chinese and English graphic menu operations, making it easy for users to operate.
