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 gas and particle analysers, IOMan interfaces, and internet-connected data loggers make it possible to create complete monitoring stations for collecting and transmitting all types of monitoring data related to air quality. The illustration opposite gives an example of what it can look like with an AR500 DOAS gas analyser, an SM200 particle analyser, additional sensors connected to IOMan modules, and a WT256 as an interface to the internet. A monitoring station can be simpler, but OPSIS has also supplied, installed, and commissioned much larger and more complex systems than this.
By establishing several monitoring stations of this type, it is possible to create measurement networks for complete air quality monitoring at local, regional, or even national level. In combination with OPSIS cloud services ODS or OPSIS measurement services OMS, a well-structured and reliable total solution is achieved for all monitoring and reporting needs.
