chapter Overview

DOG-3082YAOnline fluorescence dissolved oxygen analyzeryesIThe company's new generation of all Chinese microcomputer instruments,Using the principle of fluorescence method,Maintenance free, no electrolyte solution replenishment, no anode or cathode cleaning or replacement, no measurement drift.

DOG-3082YAFeaturing full Chinese display, Chinese menu style operation, full intelligence, multifunctionality, high measurement performance, and strong environmental adaptability.An instrument widely used for measuring oxygen content in liquids in industries such as sewage treatment plants and water treatment plants.

Basic functions and features

Notepad functionFaithfully record the operation and usage of the instrument and the occurrence time of alarms,Easy to manage.

Historical curve and digital recorder functionThe secondary table automatically stores measurement data every 5 minutes,Can continuously store dissolved oxygen values for one month. Provide simultaneously on one screen'historical curve'Display and'at fixed time and location'Two ways to query, 'historical curve'Reflecting the overall trend and process of water quality changes,Beneficial for identifying and solving problems.'at fixed time and location'The function will obtain the measured dissolved oxygen value at a specific point and time.

Digital clock function: Display the current time,Provide a time reference for the digital recorder function.

backlight functionCan be used in dimly lit or dimly lit environments, automatically adjusting the contrast to clarity according to temperature changes to suit personal habits.

Prevent program from flying deadThe watchdog program ensures that the instrument will not crash, which is a basic requirement for online instruments.

Output current setting and inspection functionManual current source function,Can check and set the output current value arbitrarily,Convenient for detecting recorders and lower level computers.

Fully intelligentThe DOG-3082YA online fluorescence dissolved oxygen analyzer adopts high-precision AD conversion and single-chip microcomputer processing technology, which canComplete various functions such as dissolved oxygen value measurement, automatic range conversion, and instrument self-test.

high reliability：componentsIntegrated onto a single circuit board, without complex functional switches, adjustment knobs, and potentiometers.

Strong anti-interference ability：The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and achieves remote transmission. Has good electromagnetic compatibility.

Waterproof and dustproof design：Protection levelIP65， Suitable for outdoor use.

RS485 communication interface：It can be conveniently connected to a computer for monitoring and communication.

Full Chinese display,friendly interfaceAdopting high-resolution dot matrix LCD display module,All data, status, and operation prompts are displayed in Chinese,*There are no symbols or codes defined by the manufacturer themselves.

Simple menu structure, text-based dialogue between peopleCompared to traditional instruments,DOG-3082YAThe functionality has increased significantly,Due to the use of a categorized menu structure,Operating methods similar to microcomputers,It is clearer and more convenient to use. No need to memorize the operation steps and sequence,You don't need an instruction manual,Follow the on-screen prompts to operate.

Simultaneous display of multiple parametersSimultaneously display dissolved oxygen value, output current, time, and status on one screen. The main display is10x10mmSpecification displays dissolved oxygen value：Eye catching and far visible distance;Three secondary displays5x5The specifications display output current, status, week, year month day, hour minute second,To meet the different usage habits of users and provide a time benchmark for secondary tables.
