Applications:
1. It is especially suitable for on-line monitoring of dissolved oxygen in the field of environment protection and sewage treatment such as on-line monitoring of dissolved oxygen in aeration basin in sewage treatment plant.
2. It can also be applied to water quality monitoring in the field of environment protection, water supply and aquaculture farm
Main features:
1.It adopts microcontroller and menu operation for easy use. It has function of controlling peripheral equipment.
2. It can simultaneously display the dissolved oxygen concentration, saturation level and temperature.
3. It has functions of automatic temperature compensation and cleaning. In addition, it support zero oxygen calibration, full scale calibration and atmospheric pressure calibration.
4. It has isolation output(***0)mA DC signal, and can have percent speed regulation for output limit and lower limit.
5. It has RS***2 or RS***5( optional) digital communication port.
6. It has functions of automatic upper and lower limit alarming and data retention.
7. The instrument has 4 control relays. The 2 of them are used to output upper and lower limit alarming signal and the other 2 adopt programmable controller aiming to combine actuation and release time so that the automatic cleaning can be realized.
8. Up to **0 sets of measuring data can be stored and viewed. (including measureing value and storage time.)
9. The structure of electronic unit is plate-type or wall-hung for easy installation, operation and maintenance.
*0. The electronic unit case has the protection level of IP*5 in order to prevent water spraying and dust pollution.
