Gas Analyzers

Model 6400T

Sulfur Dioxide Analyzer

Description

The 6400T Series analyzers uses a proven UV fluorescence principle coupled with state-of-the-art microprocessor technology to provide accurate and dependable measurements of low level SO₂. The 6400T-H₂S measures hydrogen sulfide (H₂S) by incorporating a catalytic converter set at 600°F (315°C) to oxidize H₂S into SO₂ while leaving other more difficult to oxidize sulfurs unconverted. A switching mode allows analysis of both H₂S and SO₂ concurrently.

Advanced Performance

The 6400T series analyzers offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O and built-in data acquisition capability. It includes a built-in data acquisition capability using the analyzer’s own internal memory. This allows the logging of multiple parameters, including averaged or instantaneous concentration values, calibration data and operating parameters, such as flow, pressure and lamp intensity. The analyzers combine lighter weight, rugged construction, ease of use, powerful diagnostics, modular design and outstanding performance to meet air monitoring requirements.

Stored data is easily retrieved through the front panel or via RS-232, Ethernet or USB ports either locally or by remote connection using the included APIcom™ software. These innovative features allow operators to perform predictive diagnostics and enhanced data analysis by tracking parameter trends.
