Renke RS485 4-20mA Gas Sensor Nh3 Ammonia 100ppm Gas Transmitter Price

Three range options cover low-concentration livestock and greenhouse monitoring up to high-concentration industrial and chemical plant environments within a single product series.

Sensor repeatability is guaranteed within 2%, ensuring measurement consistency across repeated readings and minimizing recalibration needs in continuous monitoring applications.

The lowest range model achieves 0.1ppm resolution, enabling detection of trace ammonia concentrations critical for indoor air quality control in poultry farms and agricultural greenhouses.

Specified zero drift range across the full operating temperature span allows users to anticipate and account for baseline shift in temperature-variable field environments.

An integrated temperature and humidity add-on enables simultaneous 3-parameter monitoring of NH3, temperature, and humidity in a single wall-mounted unit without additional sensors.

Each unit is calibrated before shipment. No secondary on-site calibration is required, reducing installation time and eliminating the need for reference gas equipment in the field.

Full output compatibility covers PLCs, data loggers, SCADA systems, and custom embedded platforms without additional signal converters or interface modules.

Broad voltage tolerance accommodates varying field power conditions including solar-charged battery systems, industrial panel supplies, and standard DC adapters without voltage regulators.

Add-on OLED screen provides clear real-time NH3 concentration readings on-site without connecting to external devices, remaining clearly visible in low-light and nighttime conditions.

High-strength waterproof housing meets IP65 protection against dust and water jets, enabling reliable deployment in chemical plants, pesticide facilities, and high-humidity livestock farms.
