Q1: What is the measurement range, resolution, and sensitivity of this ammonia (NH3) gas sensor?
A1: This ammonia (NH3) gas sensor covers a 0-100ppm range with a maximum load of 200ppm, and it delivers a resolution of 0.5ppm plus a sensitivity of 160 ± 40 nA/ppm. The NH3 sensor produces a current proportional to ammonia concentration, enabling accurate ammonia detection for the air quality sensor.
Q2: How does the electrochemical ammonia sensor detect NH3 concentration?
A2: The electrochemical ammonia sensor works through oxidation-reduction reactions at the working and counter electrodes, generating a current proportional to NH3 concentration. This allows the NH3 sensor and air quality sensor to determine ammonia levels accurately and reliably.
Q3: What is the response time and operating environment of this NH3 sensor?
A3: This NH3 sensor offers a response time of less than 90 seconds (T90), quickly reflecting changes in ammonia concentration. The air quality sensor operates from -30°C to 50°C and 15-90%RH, maintaining stable performance under varying conditions.
