DO-6800 is an online intelligent dissolved oxygen Detector produced by my introduction of foreign technology. It adopts imported components and dissolved oxygen film head, based on polarographic analysis technology, and excellent production process and surface sticker technology. Using this series of excellent analysis technology, ensure the stable, reliable and accurate long-term operation of the instrument. With Chinese/English menu operation, notepad storage measurement data, 485 communication and other functions. It can be widely used in chemical fertilizers, metallurgy, sewage treatment aeration, environmental protection water treatment engineering, pharmaceutical, biochemical, food, breeding and tap water and other solutions for continuous monitoring of dissolved oxygen value.
The new waterproof, dustproof and moisture-proof good shell (IP65) process, surface painting process, the appearance of the instrument is generous and high-end.
With automatic cleaning function (optional), the cleaning device (optional) is tap water cleaning method.
The product has high precision, high stability and strong anti-interference ability.
The use of imported components and dissolved oxygen film head, based on the new polarographic analysis technology.
Large-screen dot matrix LCD display, support for Chinese and English menus (switch between each other).
◆ Simultaneous display of multiple parameters: dissolved oxygen value, temperature, output current, alarm point, etc. are displayed simultaneously, and there is a range overrun prompt.
The screen displays the alarm status and can be accompanied by switch ON/OFF signal output at the same time.
◇ Compensation function: automatic temperature compensation 0~60 ℃, salinity compensation. Manual correction value (optional)
◇ Communication function: interface photoelectric isolation technology, with RS-485 communication interface (MODBUS protocol part compatible) (optional), can convert RS-232. The DO value corresponding to the current output of 4~ 20 mA can be set arbitrarily, and the DO value can be controlled by positive and negative 4~ 20 mA, which is widely used in some fields. Support the company's internal Internet of Things and customer-customized Internet of Things.
Two channels of 4 to 20 mA: one of them is optional.
History curve: It can record 50 sets of historical data (sampling interval 1-240 minutes), and has query function.
Notepad: can store 50 measurement data, users can query the data.
The hysteresis can be set arbitrarily to avoid frequent operation of the switch relay.
The watchdog function: to ensure that the instrument does not crash.
The core components are all from foreign brands.
◇ Factory settings can be restored. Power-down protection > 10 years.
