The 4 Series features a large, robust sensor design and is durable to withstand environmental demands. In addition to portable devices, the comprehensive range of sensors is suitable for fixed safety and emissions applications.
Introducing the 4NH3LL-100
- 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.
