Product Description DOG-3082YA Industrial Online Optical Dissolved Oxygen MeterDOG-3082YA on-line fluorescent dissolved oxygen analyzer is our company's new generation ofmicrocomputer based high-grade instrument, the principle of fluorescence method, maintenancefree, no electrolyte solution added, no anode, cathode cleaningor replacement, no measurementdrift.DOG-3082YA has the characteristics of full English display, Englishmenu operation, fullintelligence, multi function, high measuring performance, environmental adaptability and so on.Can be widely used in sewage treatmentplants, water plants and other industries of the liquidoxygen content measurement of special equipment.Basic functions and featuresNotepad function:Recording theoperation of the instrument and the use of the alarm and the timeof the alarm, easy to manage.The function of historical curve and digital recorder:The secondary meter automatically store ameasurement data per 5 minutes, can be stored for a month of dissolved oxygen value. On onescreen, it provides twoways of "historical curve" and "fixed point". The "historical curve" reflectsthe changing trend and process of water quality ingeneral, which is favorable for findingproblems and solving problems. The function of "fixed point" will get the value of dissolvedoxygen in a specific pointand time.Digital clock function : Displays the current time, provides the time reference for thedigitalrecorder function.Back-light function :Can be used in the light of the dim or completely no bright environment,according to the temperature change, automatic adjustment contrast to the most clear, in order tomeet the personal habits.To prevent the collapse of the program:Watchdog program to ensure that theinstrumentwill notcrash, which is the basicrequirements of online instrumentation.Output current setting and checkfunction : Manual current source function, can check andarbitrary set the output current value, easy to detect the recorder and the lower machine.Full intelligent:DOG-3082YAon-line fluorescence method for dissolved oxygen meter with highprecision ADconversion and microprocessing technology, can complete dissolved oxygen valueShanghai BOQU Instrument Co.,Ltd shboqu.en.made-in-china.com2measurement, automatic conversion range, instrument self-test and other functions.High reliability: Components integrated into a circuit board, there is nocomplex function switch,adjust the knob and potentiometer.Strong anti-interference ability : The currentoutput by the photoelectric coupling isolationtechnology, strong anti-interference ability, realize remote transmission. Has good electromagneticcompatibility.Waterproof and dust proof design:Protection level IP65, suitable for outdoor use.RS485 communication interface:Can be linked to computer monitoring and communication.FullEnglish display, friendly interface:Adopt thehigh resolution of the lattice graphics LCDmodule, all data, state and operationinstructions are displayed in Chinese, no symbol or codedefined by manufacturers.Simple menu structure, text - style table dialog:Compared with the traditional instrument, theDOG-3082YAfunction adds a lot of steps and operation sequence, youcan use the manual, followthe prompts on thescreen can be operated.Multi parameter simultaneous display:At the same time, the dissolved oxygen value, outputcurrent, time and state are displayed on a screen. The main displayto the specifications of the10X10mm display values of dissolved oxygen value: eye-catching, visual distance, three subdisplay display output current, status, week, month, and secondsto 5x5specifications, to meet theuser's different habits and provide second time reference.Technical indexes1.

The secondary meter for the international standard chassis,the use of fully enclosed shell.Can be installed in the monitoring room far away from the site, butalso with themeasuring pool installed in the field. The required wiring is connected tothe internalterminal of the secondary meter. The secondary meter of the shape and size of the hole opening:Shanghai BOQU Instrument Co.,Ltd shboqu.en.made-in-china.com4There arefour kinds of installationtype of the secondary meter, open holemounting type, wallmounting type, pipe type, outdoor installation.Open hole mounting: Control panel to open 138*138mm hole,the factory with a U-shapedstainless steel sheet, through the base of 89*89mm four positioning hole in the control cabinet.Wall mounting type: The first, make the secondary meter through the base of the 89*89mm fourpositioningholes, fixed in the flat plate isgreaterthan 146*146, and then fixed to the flat plateinstalled.Pipe type, outdoor installation: Through the base of the 89*89mm four positioning holes, fixedthe secondary meter.Use notes:1,Wiring: open instrument, first with a screwdriver to loosen cover the four screws, the cover onthe left to carry on, again from right to left turn. Refer to section 4.4 instrument wiring, the line isconnected, so that the line leaving some margin for the nextopen the cabinet when the line ispulled off), and then tighten the pg13.5 waterproof ring.2,Line: waterproof ring to loosen the pg13.5. Then the line to frontier (if the mounting line in acasing stay have a certain margin do not need to carry out this step). With fourscrews screwdriverloosencover, the upper cover left upwards, then from right toleft turn.Dimension: 146*146*108mmOpeningdimension: 138*138 mm
