Fixed Online Ammonia Gas Detector
The Fixed Online Ammonia Gas Detector is an industrial monitoring instrument designed for continuous detection of ammonia vapour in environments such as chemical plants, refrigeration units, and fertilizer facilities. It features a stainless steel 316 sensor housing for corrosion resistance and delivers real-time readings via LCD or optional LED display. The device supports both 4-20mA analog output for integration with DCS systems and RS485 ModBus RTU digital communication for networked monitoring.
The sensor module is designed for field-replaceable operation, allowing users to swap out faulty sensors without recalibration. Each module contains factory-preloaded calibration data that the detector automatically reads upon insertion. The system compensates for temperature variations from -40°C to +70°C and includes dual visual alarms with relay outputs to trigger external sirens or exhaust fans. The plug-and-play interface prevents incorrect connections through keyed jacks and requires only a spin-and-press action for installation.
This detector is used primarily in ammonia-based refrigeration systems, wastewater treatment plants, and agricultural storage sites where safety regulations require continuous leak monitoring. Buyers include industrial safety engineers, plant operators, and facility managers responsible for compliance with OSHA or EU Directive 2014/34/EU. Standard packaging includes a protective case with mounting brackets. Trade terms typically follow FOB Zhengzhou, with lead times of 15 to 25 days after order confirmation.

Sourcing Fixed Online Ammonia Gas Detector from Henan Chicheng Electric Co., Ltd - China Import Guide
Before ordering, verify the sensor’s calibration certificate, response time data, and environmental testing reports for humidity and electromagnetic interference. Confirm that the relay outputs match your alarm system’s voltage and current requirements. Request a user manual with wiring diagrams and software configuration tools. Avoid suppliers who cannot provide technical documentation in English or lack clear product traceability.
Lead time is typically 15 to 25 days after order confirmation. Shipping is by sea in protective cases with foam inserts. Incoterms are commonly FOB Zhengzhou or CIF port of destination. Payment terms usually require 30% deposit with balance before shipment. Buyers should confirm packaging for humidity control, as sensors are sensitive to moisture during transit. Request a shipping manifest and tracking code in advance.
Upon delivery, inspect for physical damage and verify the device powers on with correct display output. Test the 4-20mA output with a multimeter and confirm RS485 communication with a ModBus scanner. Perform a gas exposure test using a certified ammonia calibration kit and document the response curve. Retain calibration records and a signed acceptance report for compliance audits and warranty claims.
