HoldPeak Ammonia Gas Detector Tester Monitor Particle Detector ProfessionalMeterProduct Info: HP-5800G ammonia gas detector is a professional instrument for detecting ammonia gas concentration. It is designed with precise electrochemical sensors, high and low alarm settings, sound and light double alarm prompts.5800G is a good helper to effectively prevent poisoning and explosion accidents and ensure the safety of life and property. √ Colorful LCD display, temperature and humidity measurement, ℃/℉ switch, sound/light double alarm, low battery indicator, auto/manual power off.√ When the ammonia concentration reaches “AL1”, the indicator light flickers slowly and the buzzer rings slowly at the same time. When reaches "AL2", the indicator light flashes rapidly and the buzzer rings rapidly at the same time.√ With one HP-5800G NH3 detector, you can simultaneously get the value of ammonia concentration and the current temperature and humidity to achieve highly efficient and comprehensive measurement.√ The ammonia detect sensor was deigned according to the electrochemical principle which makes it have a much longer working life than those 1-year life normal sensors.√ It is widely used in poultry farms, pig farms, horse stables, animal welfare shelters,cold storage machine rooms, laboratories, pharmaceutical workshop, waste management and feed/protein optimization and OH&S verification.
