|
Galvanic’s 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 903’s 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
Galvanic’s ISO 9001-2001 quality assured tapes work together
with a specially designed mechanical and optoelectronic system to
ensure smooth and continuous operation.
Enhanced Data-Logging (512 kb)
Up to 10 months of data-logging provides user complete audit trail
for troubleshooting and report generation.
Advanced Diagnostics
Feedback from microprocessors
mounted on sensor block provide
detailed diagnostics information
such as sensor status, tape
movement, tape length remaining,
and temperature.
Field
