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 compatible 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 interface is RS485 Modbus RTU with 12-24 VDC power. 4-20 mA, battery power, LoRaWAN and an integral cellular modem have not been confirmed 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 operating range is -20 to +60 °C at 15-80% RH, but an outdoor or ingress-protection rating has not been confirmed. 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
