K100 MP - Measurement of dissolved oxygen

Equipped with analog and digital outputs, end-users can set these outputs through software. In addition, the program equipped with the instrument can support user management and maintenance of measurement probes, with the help of the "probe quality" control function. The data storage function can provide operational cost information to users based on readings.

Application: SEKO will use itspecificallyThe application of technology to Kontrol series instruments enables our instrument products to meet the measurement and analysis needs of many water treatment fields. The Kontrol 100 series instrument is an ideal product for measuring parameters in the following fields: electroplating, drinking water, irrigation systems, cooling water treatment, and floc

Coagulant dosing system, wastewater, pure water, and reverse osmosis.

Electronic control: The instrument adopts isolated current technology to ensure stable performance, and has also passed CE Level 2 certification to ensure health and safety during use.

Shell: The protection level of the shell is IP65, which can be installed on the wall or on a disc. The shell adopts a clever embedded fastener design, which makes the maintenance of the circuit board easy without disconnecting the electronic connections of the already connected numbers.

Display and human-machine interface: Parameter settings can be made through the buttons on the front panel. In addition, image display can help users quickly set and perform final viewing of program data. The Kontrol 100 series is capable of displaying operational status. The 4-color backlight displays different operating states, allowing operators to easily confirm the current status of the instrument even under harsh working conditions. Blue represents normal operation, red represents alarm status, green represents successful calibration, and red represents probe cleaning. The internal menu allows users to view the service life of the probe and the operating life of the instrument. This interactive dish

Software function: It is equipped with a universal programming language to assist users in intuitive and visible calibration settings.

The Kontrol 100 MP has a 4-20mA analog input that can expand the measurement range to include hydrogen peroxide, bromine, ozone, and peracetic acid. Based on its customized functions, various types of probes can be connected together, and then users can set the measurement range, units, and measurement parameters.

Standard RS485 serial interface, Kontrol 100 MP can communicate with local networks and connect to the network through a communication hub. This feature further enhances the functionality range of the instrument, allowing for remote settings and control through technical personnel.

Dissolved oxygen probe

Dissolved oxygen (DO) measurement refers to measuring the amount of oxygen dissolved in water

Oxygen enters water through the following methods: distributed in the surrounding air, wind, and waste produced by plants through photosynthesis.

The oxygen permeable membrane separates the positive and negative electrodes from the water sample to be tested. When interacting with the inside of the probe, an electric current will be generated, and oxygen will follow

It passes through the diaphragm. Higher pressure causes more oxygen to pass through the diaphragm, resulting in more current. The actual output of the probe is measured in millivolts

The position. This is obtained by passing current through a thermistor, which is a type of resistance that changes its output with temperature

For aquaculture, if the level of dissolved oxygen drops too low, fish in the water will suffocate and die. In sewage treatment plants, bacteria will degrade solids. If the level of dissolved oxygen is too low, bacteria will die and the degradation process will stop; On the contrary, if the dissolved oxygen level is too high, energy will be lost through the wind in the water. In industrial applications, including boilers, the feedwater must have a low level of dissolved oxygen in order to avoid corrosion and the formation of boiler scale.

Monitoring the concentration of dissolved oxygen plays an important role in ensuring process efficiency, as an increase in boiler fouling can affect heat transfer. The increase in dissolved oxygen concentration in water can improve the taste of drinking water. However, excessively high dissolved oxygen concentration can affect the anti-corrosion performance of the water supply network.
