Model 3010BR
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.
Overview
- Display reads hydrogen sulfide from 0.00ppm up to 200 (or optionally 2000ppm) with no range changes
- Analog
output and alarms can be configured to operate over any of four ranges
from 0-10ppm to 0-200ppm (optional 2000ppm) for best resolution.
- CSA approved to meet Class 1 Div. 1 Group BCD with a flammable sample requirements
