| Use boundary | Environmental monitoring hardware; safety or regulatory use requires a separately approved instrument and method |
Select the gas modules and mounting protection before ordering
This is a configurable wired instrument. The selected channel set and installation conditions determine the final measurement package.
- Choose standard NH3 at 0-100 ppm, high-precision NH3 at 0-10 ppm, standard odour at 0-50 ppm, or another reviewed channel combination.
- Up to five or six parameters can be selected by configuration. The product is not supplied with every listed sensor module installed.
- The reviewed interface is RS485 Modbus RTU with 12-24 VDC power. There is no approved 4-20 mA, battery, LoRaWAN or integral cellular claim for this product.
- Allow at least the listed three-minute warm-up. Response, alarms and calibration performance also depend on the selected gas module, airflow, humidity and cross-interference.
- The reviewed operating range is -20 to +60 °C at 15-80% RH, but no universal outdoor or ingress-protection rating is approved. Select protected mounting or an enclosure for the actual site.
- This is not a safety-certified gas detector. Safety or regulatory alarms require an approved instrument and method for the jurisdiction and application.
Typical applications
- NH3 or nuisance-odour trend monitoring in protected industrial or environmental installations
- Waste-transfer, composting or livestock-area monitoring after airflow, interference and mounting are reviewed
- Multi-parameter stations combining selected gas, temperature, humidity, pressure or particulate channels
- RS485 data input to a customer PLC, RTU, SCADA or remote-monitoring gateway
