TR-1000 Professional Chemical Plant Ammonia Gas Meter

Product Introduction

The TR-1000 Professional Chemical Plant Ammonia Gas Meter is a fixed online gas detection instrument designed for industrial environments requiring continuous toxic gas monitoring. Featuring a highly sensitive sensor, intelligent microcontroller-based monitoring circuitry, and standard three-wire 4–20 mA output, it supports integration with gas alarm controllers, distributed control systems (DCS), and programmable logic controllers (PLC).

Its explosion-proof cast aluminum housing, IP66 protection, and resistance to common sensor contaminants make it suitable for demanding applications in chemical plants, petrochemical facilities, metallurgy, power generation, and other industrial production and storage areas.

The TR-1000 platform supports multiple gas detection configurations, including ammonia (NH₃), carbon monoxide (CO), hydrogen sulfide (H₂S), chlorine (Cl₂), formaldehyde (HCHO), and toluene (C₇H₈), depending on the selected sensor and measurement range.

Working Principle

The TR-1000 uses gas detection technology selected according to the target gas and sensor configuration. The specified detection principles include electrochemical sensing and catalytic combustion.

In an electrochemical configuration, the target gas interacts with the sensing electrode, generating an electrical signal related to its concentration. The instrument's electronic circuit processes this signal and converts it into a standardized 4–20 mA output for monitoring and control systems.

The catalytic combustion principle is applicable to suitable combustible gas configurations. The exact sensing principle depends on the selected model and target gas; the supplied gas-specific table identifies electrochemical detection for the listed TR-1000 configurations.
