Portable ammonia gas detector

* High precision imported technology sensor

* Sensitive sense of smell and fast response speed

Ammonia gasThe detector has the advantages of fast response speed, good stability, high sensitivity, small size, light weight, and easy portability. It can also be equipped with an external gas sampling pump for more accurate and fast measurement results.Widely used in petrochemical, industrial production, environmental monitoring of flue gas and exhaust gas, sewage treatment, biopharmaceuticals, home environmental protection, school laboratories and other fields.

Function Description of Portable Ammonia Gas Detector:

*The whole machine has a small volume, light weight, waterproof, dustproof, explosion-proof, and shockproof design
*Safety reminder: Regular flashing lights and sound prompts
*Using high-capacity lithium rechargeable batteries, it can work continuously for a long time
*Digital LCD backlight display, sound and light, vibration alarm function
*The sensor adopts imported brand electrochemical sensors with world-class level
*The upper and lower limit alarm values can be set arbitrarily, with built-in zero and target point calibration functions, outstanding audio sound alarm, ensuring that danger can be detected even in very unfavorable working environmentsGas concentration and prompt operators to take preventive measures in a timely manner
*Large screen display of numbers, characters, instantaneous values, peak values, and minimum values
*The shell is made of special materials and processes, which are not easy to wear and tear, easy to clean, and bright as new after long-term use
