เครื่องวัดค่าบีโอดี-ซีโอดีแบบออนไลน์ (BOD/COD-UV Online Water Analyzer)

Mode of Operation The UV process has a flashlight photometer with curette formed by a gap in the analyzer case. The UV extinction of the immersion medium around the probe is measured across the width of this measuring aperture. The analyzer measurement with Spectral Absorption Coefficient at 254nm.(SAC254) for higher accurate of measuring from effect of turbidity on UV absorption is compensated by a reference measurement (Visible light source at 550 nm.) This method leaves no hazardous waste and is friendly with environmental.

Monitoring Application

The Analyzer was developed and produce in Thailand for monitoring the quality of water supply and waste water treatment process to higher precision in online water analysis. User can check the efficiency of each unit for the treatment on process. User can setup function control for automatic systems to run for making certain and easy operation. Typical applications are on industrial water, pulp and paper ,brewery treatment plant and drinking water.

Output and Communication

The BOD/COD-UV Analyzer has 4 channels for standard signal outputs (Analog 0-20 or 4-20mA.) and 4 channels for digital output (Relay 10A). There are many communications such as modbus protocol or RS485 or (WIFI) supports (option). The analyzer has built-in data logger by the expansion SD card upto2Gb for collecting measurement and alarm data.

Easy Maintenance

BOD/COD-UV Analyzer is easy to used and easy to maintenance because measurement is done in by-pass system. It also has hydraulic self-cleaning with design of sampling chamber and at the start cycle of measurement it has automatic flushing. the analyzer need calibration and service checking on yearly period.
