Item # 910 Series, Continuous Analyzers for Landfill Site and Biogas Recovery & Processing


The Nova 910 Series analyzers have been designed for monitoring recovered and processed gases from landfill 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-filter, 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. The sensors/detectors are mounted in an internal dedicated enclosure which is heated and temperature controlled to reduce drift due to ambient temperature swings. The internal sensor enclusure is removable to allow quick field change of the sensors.  The infra-red detector can be cleaned in the field if necessary by the on-site technician.  Environmental management packages are available to allow operation of the analyzer outdoors in temperatures from -20°C (-4°F) to 55°C (131°F).

On the C models with Autocalibration, all calibration functions are controlled through the display rather than manual potentiometers. The operator only has to input the calibration frequency and leave calibration gas cylinders connected to the analyzer - the rest is automatic. Diagnostics and troubleshooting information are also included in the display interface of the C models. This assists operators to quickly determine the cause of an alarm and get the analyzer back on-line.
