The 903W H2S Analyzer Total Sulphur Analyzer

903W H2S Analyzer

 
903W H2S Natural Gas Analyzer
 

Galvanicís 903 W H2S Analyzer is designed to measure H2S in gaseous streams. The detection system is based on the highly accurate and specific lead acetate tape method. The 903ís patented analysis algorithm improves repeatability and linearity, while also increasing dynamic range without the need for dilution. This analyzer will support ranges up to 0-2000 ppm without dilution.

Features of the 903W H2S Analyzer /
Total Sulphur Analyzer

Optical Tape Counter
Optical tape counter ensures exact spacing of stains as well as keeping track of tape consumption. Tape life of 5-14 weeks can be expected, depending on the application.

Advanced Digital Sensor at Measurement Point
AD converter is located at the sensor increasing further accuracy by eliminating noise associated with transmitting analog signals.

Proprietary Humidifier
Unique humidifier design using permeable membrane reduces dead volume providing faster response time.

Hazardous Area
Certified to CSA (C/US ) Class 1, Div 2 Groups B,C, and D, T3

User Friendly Software
Easy-to-use Windows-based PC software with graphical user interface for monitoring and analyzer configuration. Can be used while laptop is connected to front of analyzer or remotely via serial link or ethernet.

Indicator Lights
10 LE D indicator lights provide quick status.

Galvanic TAPE ASSURANCE SYSTEM
Galvanicís ISO 9001-2008 quality assured tapes work together with a specially designed mechanical and optoelectronic system to ensure smooth and continuous operation.

Enhanced Data-Logging (512 kb)

About H2S & Total Sulfur Lead Acetate

The lead acetate tape method for the detection of hydrogen sulfide (H2S) and Total Sulfur in gaseous streams is based on the established principle that H2S reacts specifically with lead acetate to form a brown lead sulfide stain.

The concentration of H2S is directly proportional to the rate of change of staining on the lead acetate tape. This principle is the basis for a number of ASTM methods, and is by far the most reliable and simplest way to measure H2S in process.

The analyzer moves the treated paper tape one section at a time. Depending on the sample concentration, the tape will begin to darken at a rate proportional to the concentration of H2S in the sample stream. The analyzer exposes a fresh section of tape to the sample inside the sample chamber every 3 minutes.

The lead acetate series of H2S analyzers are third generation systems designed to meet increasing demands for low-level measurement in pipelines and process. The models to choose from are the 903WTS and the 903.

Our analyzers are designed with the following in mind:

  • Low maintenance

  • Extended tape life

  • Fast speed of response (under 20 sec. to alarm)

  • Low power consumption

  • Optional total sulfur measurement

  • Multiple streams

  • Auto calibration

  • Remote communications
