HI4421 laboratory high-precision BOD and dissolved oxygen analyzer
Product introduction of HI4421 laboratory high-precision BOD and dissolved oxygen analyzer:
HI4421Professional laboratory dissolved oxygen analyzer, capable of measuring multiple parameters:DO,BOD,OUR,SOURPressure, temperature. Its main characteristics are:240×320Dot matrix color screen background light display, automatic data storage, automatic endpoint locking mode, and user-defined setting function. There are multiple display modes for operators to choose from: basic information display,GLPInformation display, chart mode, and storage data display mode.
Automatic calibration and user-defined calibration dual calibration modes ensure measurement accuracy. There are three storage modes for you to choose from: automatic storage, manual storage, and automatic locked storage (only used for dissolved oxygen measurement). Equipped with automatic endpoint locking function for easy storage and recording.HI4421Up to storage space100group,Each group can store10000A measurement data.
