多气体分析仪

580DR1空气报警监测器，扩散式传感器，远程报警装置
The Nova 580 Series Carbon Monoxide (CO) alarm monitors are designed for the continuous detection of CO in ambient air. The CO sensor is capable of excursions over 1000 PPM with no damage. The CO sensor is of the disposable electrochemical type with an expected life of between 3-4 years. The sensor needs no warm up time and is ready to go as soon as the monitor is turned on.

600便携式多气体环境空气分析仪 - 600系列
The Nova 600 Series Portable Multi-gas Ambient Air analyzers are convenient and accurate portable instruments for monitoring up to six gases simultaneously from ambient air samples. A built in sample pump draws in the sample gas where it is analyzed by up to six separate detectors. These detector outputs are then amplified and displayed on separate, easy-to-read digital meters.
The electrochemical sensors for O2, CO, SO2, NO, NO2, H2, CL2, NH3, and H2S have a long service life of several years. The microprocessor NDIR detector for CO2, the RH sensor and the temperature sensor are all non-consumable.

900系列连续分析仪，垃圾填埋场分析仪和沼气回收与处理
For continuous analysis of Oxygen (O2), Methane (CH4), and/or Carbon Dioxide (CO2) in recovered gases from landfill and biogas sites.

913C连续分析仪，垃圾填埋场沼气回收与处理 - 自动校准 - O2，CO2和CH4
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 th analyzer outdoors in temperatures from -30 °C (-22 °F) to 70 °C (158 °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.
