HK-1351 Dissolved Oxygen Online Monitor
HK-1351 Dissolved Oxygen Online Monitor
Product details
The HK-1351 dissolved oxygen analyzer is a high-performance online measuring instrument newly launched by the company. The instrument adopts a dissolved oxygen sensor with a measurement accuracy of up to micrograms, which has high sensitivity, fast reaction speed, and can continuously measure online. Instruments can be applied in industries such as power, chemical, metallurgical, food, and pharmaceutical.
◆Independently developed electrode with small zero drift, low residual current, fast response speed, long service life, and simple maintenance
◆Temperature measurement can be configured as platinum resistance, thermistor, or manually set
◆Equipped with an embedded operating systemARM9Processor, secure and stable
◆Internal two independent power modules improve reliability and reduce on-site interference
◆Durable cast aluminum casing, suitable for various installation methods
◆Two channels can be configured with multiple modes of isolation current output function, supporting maximum800Ωload
◆Adjustable alarm delay function to reduce misoperation caused by on-site interference
◆Can be usedSDCard implementation for on-site upgrade or data retrieval
◆Large capacity file system for storing large capacity historical data
◆Four relay outputs, configurable with high and low alarm outputs, and electrode cleaning function
◆quarantineRS485Interface standardsModbusThe data bus of the protocol realizes digital fieldbus technology
