Product catalog summary

Product Description: The Electrochemical Ammonia Gas Sensor is designed to measure NH3 concentration in the gas phase and can replace standard 4-series electrochemical NH3 sensors from other manufacturers.

Performance Characteristics:

NH3-20: Nominal range 0-20 ppm, maximum overload 50 ppm, sensitivity 0.150 ± 0.035μA/ppm, response time ≤ 90 s, resolution 100 ppb.
NH3-100S and NH3-100L: Nominal range 0-100 ppm, maximum overload 200 ppm, sensitivity 0.135 ± 0.035μA/ppm, response time ≤ 45 s (NH3-100S) and ≤ 90 s (NH3-100L), resolution 0.2 ppm.
NH3-500S and NH3-500L: Nominal range 0-500 ppm, maximum overload 1000 ppm, sensitivity 0.035 ± 0.015μA/ppm, response time ≤ 40 s, resolution 0.5 ppm.
NH3-1000S and NH3-1000L: Nominal range 0-1000 ppm, maximum overload 2000 ppm, sensitivity 0.025 ± 0.008μA/ppm, response time ≤ 40 s (NH3-1000S) and ≤ 120 s (NH3-1000L), resolution 1 ppm (NH3-1000S) and 2 ppm (NH3-1000L).
NH3-2000: Nominal range 0-2000 ppm, maximum overload 4000 ppm, sensitivity 0.015 ± 0.005 μA/ppm, response time ≤ 90 s, resolution 2 ppm.
NH3-5000L: Nominal range 0-5000 ppm, maximum overload 10000 ppm, sensitivity 6 ± 3nA/ppm, response time ≤ 120 s, resolution 50 ppm.

Environmental Specifications: Operating temperature range -40℃ to 40℃, pressure range 1±0.1atm, humidity range 15% to 90% RH non-condensing. Expected operating life is 5 years in clean air, with a storage life of 6 months in original packaging.

Safety and Installation Notes: The sensor is intended for life-critical applications and requires careful adherence to calibration procedures using certified target calibration gas. The housing should not be opened due to harmful electrolyte inside. Avoid exposure to high concentrations of solvent vapors and mechanical overstress.

Physical Characteristics: The sensor is housed in ABS material, weighs approximately 5g, and has no specific orientation requirements.

Output signals from the sensor pins are different. Inappropriate use of the pins in product design will affect the sensor functionality. Exposure to high concentrations of solvent vapors should be avoided under any condition. Mechanical overstress may cause deformation or cracks of the plastic enclosure of the sensor. If the

sensor is used in extreme environmental conditions, please contact us for more details. Safety Note: The sensor is designed to be used in certain instruments for life critical applications. To ensure the sensor functioning per its specifications inside the instrument, it is required to read the instrument user's guide carefully and comply with the calibration procedures by using certified target calibration gas before each use. Failure to do so may cause serious injury and fatality. Please do not open the housing because the electrolyte stored inside is harmful. It is highly recommended for customers...
