Field-proven H2S analyzers

Why H2S & Sulfur Colorimetric Tape Analyzers?

The most cost effective & accurate H2S analyzer available

Specific only to H₂S (no known interferences proven by thousands of world wide applications)

1. Conformity to ASTM analytical methods D4084-82, D4468-85, and D4045-81
2. Automatic self-zero. The ASI KECO H₂S analyzer does not suffer from a ‘zero drift’ as seen in other analyzers (see data sheet) thus eliminating zero gas requirements.
3. Versatile. The analyzer will not suffer in the event of process changes–no matter how drastic.
4. Wide Range Ability. The analyzer is capable of measuring from the low ppb levels thru ppm up to 100% saturation.
5. Analyzer holds calibration long term.
6. Linear Response. The tape darkening is proportional to H2S concentration so the response is fully linear.
7. Dual processors for both communication and analysis allows for essentially 100% continuous analysis time. Other analyzers with only one processor cannot continually analyze and communicate at the same time which lags the response time.
8. The humidifier assembly in the ASI KECO H₂S analyzer has no dead volume which results in faster response & no absorption of H₂S. In addition, the humidification membrane eliminates the possibility of liquid carry over which would break the tape.
9. 18 AD converter equals less tape consumption, faster response & lower range ability.
10. Direct read display–no codes to memorize or characters to refer to.
11. Easily return the analyzer to Factory Calibration by choosing this option in the electronic menu of the analyzer.
12. Automatic calibration (No Attendant Required)
