Overview

The Ammonia Gas Sensor Device, in combination with the principle of coulometry, delivers a high-precision gas detection technology. The higher the ammonia concentration the faster the sensor will be drained. Therefore the sensor lifetime will deteriorate rapidly and more maintenance will be needed.

Features

• Smart measuring system

• Works on back Ammonia concentration continually

• Combined with intelligent algorithms it has better adaptability to the environment

• Higher accuracy in detection and stable zero point

• With pump, no calibration with NH3 gas needed

• New microcircuit design, strong anti-electromagnetic interference ability

• No temperature and humidity influence

• RS485 output, 5-12V DC power

• Stainless steel housing, water and dust proof, anti-corrosion

• The detection range is automatically adjusted to the concentration range of the

• measured gas, from ppb to higher ppm level

• Continuously monitors its own fault conditions, Sensor, Pump, Power etc.

• RoHS eco-friendly design

• Self-monitoring of the sensor function

Applications

· Livestock Farming

· High Concentration Monitoring

· Leakage Detection

· High Temperature Conditions

The ammonia concentration in the livestock industry has various negative effects on the animals and our environment. In a high ammonia concentrated environment the livestock has a higher risk of contracting a disease. The air surrounding the farm, both inside and outside, is polluted and has a pungent smell.

ECtox’s big advantage, while continuously working with a high ammonia concentration, is its long lifetime. A pump easily transports the gas to the sensor without the need to calibrate. The sensor can be used for livestock farms, ammonia leakage detection and cooling storages. The output signal, RS485 (Modbus), will effortlessly connect with a gas detector, DCS, PLC or wireless systems.

Note: Temperature (0-25) ℃, humidity (30-50)% RH, the measured gas concentration is within the range, there is no gas environment that affects the warm-up time mentioned above
