The ES30A portable gas detector produced by our company is an industrial gas leak detection and alarm device with high sensitivity and wide range. Using imported catalytic combustion sensors controlled by embedded microprocessors, combined with large-scale digital integrated circuits and low-power components, the gas concentration signal in the air is converted into an electrical signal, which is visually displayed on a LCD screen. When the measured gas concentration in the environment reaches or exceeds the preset concentration value, the instrument immediately emits a triple alarm of sound, light, and vibration, effectively ensuring the safety of workers' lives and the reliability of production equipment.
The detector housing is made of high-strength engineering materials and refined dual color materials of composite elastic rubber, which have high strength, good hand feel, and are waterproof, dustproof, and explosion-proof.
Small and lightweight body: This gas detector is designed in a pocket size, with a small and lightweight body, making it more convenient to carry. The body is smaller than a regular phone.
Lithium ion rechargeable battery: 1500mAh, ultra long standby for seven days; Polymer lithium battery, environmentally friendly, lightweight, and large capacity; Good heat dissipation can avoid interference and radiation.
