The AMI Model 3010BR Trace Hydrogen Sulfide (H2S) analyzer provides H2S monitoring in an unprecedented low cost, compact size, virtually maintenance-free package. Using AMI’s patented cell block technology, it allows a specially modified electrochemical sensor to operate on oxygen-free sample gas, eliminating the need for hazardous-waste generating lead acetate tape.
The Model 3010BR provides a complete, industry proven electronics package and integrated sample system. It is offered for about a third the price of competitive models.
AMI’s patented cell block allows the analyzer to be built with almost no possibility of internal leaking, with minimal volume and with front-panel sensor access. All sample handling components – the flow meter, needle valve and a four-way sample/span/off selection valve – are integrated into a solid metal block. Connections between them are drilled passages in place of long lengths of tubing. The result is a highly reliable sample system with all necessary components provided, and a fast response time – hydrogen sulfide is a “sticky” gas so minimizing the sample path is vital to get the least possible wetted surface area.
The expected sensor life is from one to two years depending on environment. The sensor is immediately accessible on the front panel of the analyzer, and can be replaced in seconds.
For low temperature operation an integral (approved) explosion-proof heater can be supplied. This unit directly heats the cell block and thus is extremely efficient, allowing operation off a solar panel/battery system down to -20°F. The heater option does not require additional enclosures or wiring, or change the footprint in any way. For extreme environments down to -40F, an outer insulated enclosure can be supplied, but no additional power is required.
The analyzer is approved by CSA for operation in a Class 1 Division 1 Group BCD hazardous area with a flammable gas as the sample. No additional safety barriers are needed. The analyzer can be calibrated and sensor replaced without declassifying the area because the analytical electronics are intrinsically safe, protected by internal safety barriers.
The electronic and software package is exceptionally complete, and all features are provided as standard with no additional cost (except for the heater). It is capable of operating off a battery and solar panel, and it logs power brown outs and failures should they occur. It also logs the ambient and the sensor temperatures and so can be used to alarm on the failure of a catalytic heater if one is used in a meter building. It tracks the life of the sensor and indicates the remaining life. It logs the calibration history. It logs the hydrogen sulfide readings over its operational (output) range, and also tracks excursions of up to ten times that range.
The analyzer can be wall-mounted with 4 externally accessible screws, or bolted to a 2” pipe using standard U bolts.
