Product introduction
DS500 series is an in situ water quality analyzer based on advanced sensor technology, which can be used in portable field, and can also be deployed for long-term online monitoring of water level and a variety of water quality parameters. With small diameter and rich measurement parameters, DS500 series can be widely used in surface water/groundwater, aquaculture, environmental protection, geology, water supply and drainage and other water quality in-situ testing scenarios. 
Performance characteristics
- Massive optional modular sensors
DS500 series provides a large number of modular sensors, users can be selected according to their own test needs, modular sensor replacement does not need to return to the factory, can be easily completed at the test site. Modular sensors can also be completed on-site
- Compact titanium exterior 売 main engine in small size
DS500 series all adopt titanium metal housing, can be applied to bad water quality test environment, because titanium metal is stable, will not introduce new variables due to the deployment of water quality meter, present the in-situ water quality characteristics to the greatest extent. The main engine adopts a small size compact design, the DS500 machine diameter 49mm, can take into account the diameter of the required small test space, such as the minimum 50mm diameter of environmental groundwater monitoring Wells,DS500 can easily complete in-situ rapid testing or long-term deployment.
