Ambient Temperature 0-50°C (without enclosure)
Ambient Humidity 0 – 95% non-condensing
Electronics Dual processor design with intelligent
colorimetric sensor. To achieve greatest
sensitivity sensor uses 24 bit AD converter
equipped with temperature monitor on sensor
block. Sensor automatically calibrates on every
cycle to prevent drift.
Optical tape counter optimizes tape usage and
provides exact measurement of tape used.
User can program low tape alerts/alarms.
Real time clock for accurate event time
stamping.
Software Windows based software for configuration and
monitoring. Software includes advanced
configurable features for stream switching,
automatic calibration, multi mode H2S and total
sulfur measurement, reference and zero gas
test, and multi-ranging.
Humidifier Permeable membrane humidifier system
facilitates faster response time and eliminates
moisture carry-over to lead acetate tape.
Memory Field programmable memory Firmware for unit can be upgraded in the field.
Data Logging Up to 10 months of H2S
concentration data logs. 512 Kbytes non-
volatile memory for data logging and audit trail.
Options Total sulfur system, dilution system, high
pressure sampling system, solar power, back
panel, low pressure sensor, low hydrogen
sensor, auto-cal, and enclosure / cabinets
(temperature
Ranges Up to 0-500ppm with no dilution; up to 0-100%
with permeation dilution system
Low Range 0-1ppm or less (H
2
S or total sulfur). Please
