Products for Air Quality Monitoring
OPSIS - Model 300 - Air Quality Monitoring System
OPSIS System 300 includes emitter, receiver, optical fibre, and DOAS analyser. The system is offered in three basic versions: System 300BASIC for monitoring the levels of NO2, SO2, and O3. System 300BTX for measuring benzene, toluene, and xylene levels. System 300EXT which combines the measurement capability of BASIC and BTX.
OPSIS - Laser Diode Systems for Gas Analysis
Laser diode-based monitoring systems for air quality monitoring. As an alternative to the DOAS systems, OPSIS also offers gas analysis based on laser diode technology, TDL. TDL technology is a good choice if only single or a few types of air pollutants are to be monitored, or if a certain measurement performance for a specific type of pollutant is to be achieved.
OPSIS - Model SM200 - PM10 and PM2.5 Particulate Monitor System
SM200 captures and monitors particles in the air. The OPSIS particle monitor SM200 automatically monitors the particle concentration in the ambient air. At the same time, it saves samples of the particles for manual analysis of, for example, airborne heavy metals.
OPSIS - DOAS Products for Gas Analysis
Differential Optical Absorption Spectroscopy (DOAS) is the core technology in the OPSIS product portfolio, where a combination of light transmitters, light receivers, optical fibres, and analysers enable the measurement of gaseous pollutants in ambient air.

OPSIS - Sensor Interfaces System
When monitoring the air quality, it is often also of interest to collect meteorological parameters such as temperature, air pressure, wind speed, and wind direction. Signals from such sensors are easily integrated into OPSIS monitoring systems, both in analysers and in stand-alone data loggers. In simple cases, the sensors have analogue outputs for the measured value and perhaps a contact output to signal status. The signals are then connected to the measurement system via the OPSIS modular IOMan interface. IOMan can handle voltage and current signals (active and passive), closing and opening switches, and pulse counters, among others. More advanced sensors can have communication protocols to deliver information and OPSIS data loggers support about twenty different protocols. OPSIS can supply several types of sensors, but it is also possible to connect sensors from other suppliers.
OPSIS - Model DL256 - Stand-Alone Data Logger
The OPSIS DL256 is a stand-alone data logger with the same capacity and functionality as the data loggers included in OPSIS gas analysers. The DL256 can therefore be adapted to virtually any data collection requirement. The DL256 collects data with one-minute time resolution and has memory capacity to operate for several years, even with many connected sensors. Communication software for remote control via serial connection is included in the data logger. The DL256 is an adequate alternative to the WT256 and is mainly used in cases where it is not possible or desirable to connect the equipment to the Internet.

OPSIS - Air Quality Monitoring Calibration Bench System
Calibration is needed to show that the measurement results correspond to reality. If they do not, the instrument readings can be adjusted. There are a number of different products for calibrating OPSIS monitoring systems. Most often, a calibration bench model CB100 is used. It is used together with a light source (CA150/RE060) and a receiver (RE060) at each end of the bench so that a monitoring path is formed along the bench.
OPSIS - Optical Multiplexer System
An optical multiplexer is used when an OPSIS system has more than one monitoring path. The multiplexer is connected between the monitoring paths and the gas analyser. Measurements are then made in sequence along each monitoring path. There are several models of multiplexers with the capacity to connect different numbers of paths. For DOAS systems the MX004 or MX009 is used. The LD500 laser diode gas analyser uses other types of multiplexers. In all cases, the multiplexer means that a single gas analyser can cover a large area with monitoring paths in different directions. This provides a very cost-effective and area-effective system solution.
OPSIS - Meteorological Sensors
Monitoring systems from OPSIS are often supplied with sensors for monitoring various meteorological parameters such as: wind speed and direction in two or three dimensions (WX500 series), temperature (PT100), solar radiation (GR180), precipitation (RG500), atmospheric pressure (BM100), humidity (HX110). The sensors can be easily connected to our monitoring systems, either directly or via our data acquisition products (IOMan, DL256, WT256).
OPSIS - Air Quality Monitoring Instrument Houses
Our instrument housings provide the optimal operating environment for the monitoring equipment. They are designed to operate trouble-free for many years in the most varied climates and environments, in all types of air quality monitoring. At the same time, they can provide a comfortable and safe working environment for the staff who maintain and calibrate the instruments. There are several different models to choose from. The choice depends on the application and the extent of the monitoring equipment to be housed.
