Page 8: Equipment Overview
→ COOH The electronics built into the models 330S and 331S have been programmed to measure the rate of darkening over time which, in turn, gives the hydrogen sulfide concentration level. When no H S is in contact with the H S sensing tape, the analyzer sensor reads 1000 mV (+/- 100 mV). -
Page 9: Analysis Cycles
S sensing tape is measured in analysis cycles. An analysis Cycle lasts up to a maximum of 720 seconds (12 minutes). Do not change the Maximum Analysis Time, consult Envent Engineering Ltd. Analyzers sold prior to Mid-August 2016 are set to have a 360 second analysis cycle. - Page 10 However, RRA values can be used as a trigger alarms setpoint in case the application requires a rapid response time (less than the RRA Analysis completion).

S sensing tape; refer to Figure 7 . Figure 7. Envent's Humidifier Unit for 330S & 331S The humidifier works by using Nafion Tubing. This material has the capability to transports water vapor from the most humidified medium to the driest medium. The sample gas traveling inside the Nafion tube is dryer than the outside of the tube, which is being saturated with water, thus, humidifying the gas sample. -
