HoldPeak Ammonia Gas Detector HP-535G

Ammonia gas detector with high accuracy: measures ammonia gas 0 ~ 100 PPM, ammonia gas resolution 0.1 PPM, accuracy +/- 2%. 

Measures the ambient temperature from -10 ~ 50 ℃, ℃/! switchable.
Temperature and humidity meter: Ammonia gas is produced faster in a humid, warm environment. Therefore, when detecting ammonia gas (NH3), you should also keep an eye on temperature (℃/! ) and humidity.

Alarm indicator light: AL1 and AL2 alarm limit values are adjustable. Slow light flash and buzzer displays alarm level "AL1" reached, fast light flash and buzzer displays alarm level "AL2" reached. This portable ammonia detector comes with a storage case for testing.

Wide application: this air quality meter is important as there are many gases that can be harmful to organic life. It is widely used in poultry farms, pork farms, horse stables, animal shelters, cold rooms, laboratories, pharmaceutical workshops, waste management and feed/protein optimisation as well as occupational safety tests.
