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) • 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 NOVA ANALYTICAL SYSTEMS www.nova-gas.com

DESCRIPTION The Nova 910 Series analyzers have been designed for monitoring recovered and processed gases from landll and biogas sites. This equipment continuously removes moisture from the wet sample gas without the need for cooling water, compressed air, or failure-prone thermoelectric elements. The 910 Series comes complete with pre-lter, sample pump, flow meter, continuous moisture removal system, long-life O2 sensor, infrared CO2/CH4 detector, low flow sensor, alarm relay contacts, and 4-20mA outputs for each gas measured. Sensors / detectors are mounted in an internal dedicated enclosure...
