631-XPortable hydrogen sulfide analyzerIntroduction:

631-XPortable hydrogen sulfide analyzerUsing industry proven gold film sensor technology to detect low levels of H2S. With just a touch of the button, 631-X can detect 0.003-50ppm of hydrogen sulfide in the air within seconds. Durable, reliable data, and easy to operate. The sturdy casing enables it to meet the needs of field and laboratory use, as well as corresponding environmental regulations, odor control monitoring, washer cleaning efficiency, control room corrosion monitoring, and other application requirements.

Instrument features:

• Low concentration detection: 631-X can detect H2S content as low as 0.003 ppm -50 ppm in the air, perfectly meeting the application requirements of corresponding environmental regulations, odor control monitoring, washer cleaning efficiency, control room corrosion monitoring, and other aspects.
• Gold film sensor: After over 35 years of on-site and laboratory validation, our unique gold film sensor ensures that the instrument obtains reproducible test results in a wide range of applications.
• Durable construction: The 631-X is enclosed in a sturdy metal casing, which can withstand harsh working conditions and provide precise test results whether in the field or laboratory.
• Easy to operate: The quick reference guide below the handle helps simplify daily use, and the easy to read display screen is equipped with an automatic brightness adjustment function that automatically activates in low light conditions.
• Regulatory compliance: 631-X is actively being used by many regulatory agencies and landfill, water treatment, and waste management facilities around the world.
• Survey mode: In survey mode, 631-X continuously extracts air samples to help customers scan hydrogen sulfide hotspots and take targeted corrective measures quickly.
• Data recording (optional): If equipped with data recording function, 631-X can store up to 1000 samples of data, including date and time.
• Automatic sampling mode (optional): 631-X provides an optional automatic sampling mode that can be edited to sample at different time intervals of 1-60 minutes.
• On site regeneration: With the optional power converter accessory, the 631-X sensor can be regenerated on-site, improving its ability to be tested in the field
