910 SERIES
CONTINUOUS ANALYZERS FOR
LANDFILL SITES AND BIOGAS
RECOVERY & PROCESSING
Models A & C

APPLICATIONS
For continuous analysis of oxygen (O2), methane (CH4), and/or carbon
dioxide (CO2) in recovered gases from landfill and biogas sites.

A - BASE MODEL
• Easy to use manual potentiometer calibration with LCD digital
displays for each gas
• Temperature controlled sensors for maximum stability
• Long life electrochemical O2 sensor
• Infrared detector for reliable measurement of CH4 & CO2;
detector may be cleaned in the field
• Stainless steel hard tubing and corrosion-resistant components
for internal sample path
• Cabinet positive-pressure system to minimize the corrosive
effects of hydrogen sulfide (H2S) on cabinet electronics &
sensors
• Built-in sample pump, pre-filter, filters, and flow meter
• Automatic moisture removal without the use of cooling water,
compressed air or failure-prone thermal-electric elements
• Back pressure regulator to allow user to measure and minimize
vacuum effects if the sample is vented back to blower
• Rugged NEMA4 (IP65) enclosure
• Isolated 4 - 20 mA output for each gas

913C (O2, CH4, & CO2 analysis
with Full Autocalibration)

C - AUTOCALIBRATION MODEL

OPTIONS

• Same features as Base model, plus:
• Automatic analyzer calibration with full-color touch screen
LCD display
• 'Cal-Now' feature initiates full calibration with a single
swipe of magnetic wand

• Gas hi/low alarms with relay contacts
• RS232, RS485, MODBUS®, and Ethernet outputs
(available on Model C only)
• Class 1 Division 2 Group BCD rated purge kit for
use in hazardous areas
• Outdoor weather packages for operation from
-30°C (-22°F) up to 55°C (131°F)
• O2 measurement by paramagnetic detector
• In-cabinet LEL monitor to interrupt analyzer power in the
event of an internal gas leak

CALIBRATION
• Ambient air for O2 span and CO2 & CH4 zero
• Analyzed calibration gas of CO2 and CH4 in nitrogen for
CO2 & CH4 span and O2 zero
