ATOMIC ABSORPTION MERCURY ANALYZER AZA1344A
The AZA1344A Atomic Absorption Mercury Analyzer is a laboratory gas-phase mercury analysis instrument designed for sensitive and reliable measurement of mercury concentration. The system complies with the Mercury Measuring Instrument Standard and incorporates a stable optical system, automated gas-flow control, and constant-temperature absorption cell technology.
The instrument maintains excellent baseline stability and provides reliable short-term and long-term measurement accuracy. Its constant-light optical path helps compensate for changes in the light source, improving long-term measurement stability.
A microcontroller automatically controls the solenoid valve to switch between the measurement state and cleaning state. During measurement, the system operates as a closed-loop gas path, while the cleaning process uses an open-loop gas path, facilitating efficient pipeline cleaning and stable measurement results.
The mercury gas continuously passes through the absorption cell, allowing measurement data to be obtained approximately every 2 seconds.
