- The Honeywell 4NH3LL-100 is a 3-electrode electrochemical sensor designed to detect ammonia (NH3) levels ranging from 0 ppm to 100 ppm.
- This long-life sensor is suitable for both portable and fixed gas detection in diverse applications, including farming, refrigeration systems, and various industrial sectors such as food, semiconductor, and chemical industries.
- Sensor can operate constantly with background levels of ammonia without affecting the sensor’s performance - ideal for livestock and poultry farming applications.
- The sensor operates effectively within a temperature range of -20°C to 40°C and a humidity level from 15% to 90% RH. (Could be operated intermittently from -40°C to 50°C)
- It has a lifespan of two years in fresh air and is backed by a 12-month warranty from the date of shipment.
- The sensor exhibits a sensitivity of 30 nA/ppm (±20 nA/ppm) and a response time of less than 90 seconds.
