Introduction: The company's dissolved oxygen is a highly intelligent online continuous monitor. Can be equipped with polarographic electrodes, automatically from ppb level to ppm level wide range of measurements, is to detect boiler feed water, condensate, environmental water and other industries liquid oxygen content measurement of special equipment. Polarographic electrodes in response to fast, stable, reliable, low cost, suitable for large-scale use of thermal power plants. Coupled with the full range of Chinese, multi-functional and direct networking of the water quality instruments produced by our company, it is unique in its kind and has been widely used in the field of "practical, convenient and functional". Specifications: 1, Chinese liquid crystal display, Chinese menu operation; 2, measuring range: 0 ~ 100.0 ug / L; 0 ~ 20.00 mg / L (automatic switching); 0 ~ 60 ℃; Saturation: 0 ~ 200.0%; (Press the "Enter" key in the measurement state to switch between the dissolved oxygen concentration value and the saturation display) Resolution: 0.1 ug / L, 0.01 mg / L, 0.1 ° C; 0.1%; 3, the basic machine error: ug / L: ± 1.0% FS; mg / L: ± 0.5% FS, temperature: ± 0.5 ℃; 4, the whole machine shows repeatability: ± 0.5% FS; 5, the overall stability of indication: ± 1.0% FS; 6, automatic temperature compensation range: 0 ~ 60 ℃, 25 ℃ as a benchmark; Response time: <60 seconds (98% of final value, 25 ° C) 37 ° C: 98% final value <20 seconds; 8, the clock accuracy: ± 1 minute / month; 9, the output current error: ≤ ± 1.0% FS; 10, isolated output: 0 ~ 10 mA (load resistance <1.5KΩ); 4 ~ 20 mA (load resistance <750Ω); 11, RS485 communication interface (optional); 12, Alarm Relay: AC220V, 3A; 13, Power: 220V ± 10% 50 ± 1HZ; Electrode installation 1: Flow-through installation: The measuring cell adopts the flow-through structure, which is suitable for the liquid and liquid pipe connection of soft and hard pipe. Shell made of stainless steel, the installation is very convenient. Out of the water pipe diameter Φ6, Φ8, Φ10 and Φ12 four specifications to meet the different needs of users. 2: Submerged installation: the electrode lead out from the sheath tube, and then the top of the electrode thread and sheath tube thread can be connected with the raw material. Make sure the top of the electrode and the cable are not filled with water. 3: Pipeline installation: the tip of the electrode can be connected with the pipe thread. 4: Flange installation: According to customer requirements set Lan plate such as: DN80, DN100 and so on.
