YJ-COD2 type COD online monitor monitor water quality index COD COD analyzer

YJ-COD2 type COD online monitor technical parameters: ☆ measurement method: UV ultraviolet absorption ☆ Test Range: (0 -200.0) mg / l ☆ detect offline: 0.1mg / l ☆ Resolution: <0.1mg / l ☆ Accuracy: standard solution <10%; water samples <20% (ratio of complex waste water needs to be converted) ☆ reproduce degree: <5% ☆ measurement cycle: 3min ☆ uptime: ≧ 720h / times ☆ Span drift: ± 5 % FS ☆ do sample interval: continuous, one hour, two hours. . . 24 hours, triggering ☆ Calibration interval: manually or by selected intervals and time automatically (1-7 days) ☆ cleaning interval: manually or by selected intervals and time automatically (1-7 days) ☆ maintenance intervals: > 1 month, each about 1 hour ☆ reagent consumption: approximately 720 samples each reagent around ☆ HMI: 7-inch, 70,000-color, 800 x 480 resolution, TFT true color touch screen ☆ print: Reserved Printer interface to an external industrial micro-printer (optional) ☆ storage: 20,000 data, non-volatile, automatically overwrite the oldest data is full (can be increased with 40,000 data) ☆ communication interface: 1 channel RS232 or RS485 digital interface , supports MODBUS communication protocol or custom protocol 1 analog 4 ~ 20mA (20mA corresponding adjustable range) ☆ pretreatment system: self-cleaning, cleaning, precision filter function to ensure a good representative sample at the same time, but also to avoid Large suspended particles clogging pipes (optional) ☆ Dimensions: 900 × 600 × 450 (mm) ☆ Weight: 50kg ☆ Power: AC220V ± 20%, 50Hz ± 1% ☆ Power: 300W ☆ ambient temperature: 5-40 ℃ ☆ Humidity: ≤85% YJ-COD2 type COD online monitor features: ensure high measurement accuracy: ■ The use of US MasterFlex peristaltic pump technology, constant speed ■ thermostat module imported from Germany to ensure that the electrodes work environment , from the external environment impact ■ with double filtration can be adapted to high suspended solids, magazines, water floats. Where sophisticated pretreatment system: self-cleaning, cleaning, precision filter function to ensure a good representative sample at the same time, but also to avoid large suspended particles clogging the pipeline, with the upper part of the host can be separated. (Standard) to ensure the stability of the product: ■ The use of US MasterFlex peristaltic pump technology ■ sampling system used in Germany's nine-valve technology, to rid itself of the oppression of the aging pipeline ■ adoption of the European power system dedicated power supply systems, anti-electromagnetic interference , grid instability greatly reduce sales costs: ■ the super abrasive resistant peristaltic pump tubing ■ All pipes imported from all over the world with high temperature, corrosion import 3-fluoro-4-fluoro-material, an inner diameter of 1.5 mm, without plugging ■ The storage capacity of 20 000 records, the oldest data will automatically overwrite after full, power-down data is not lost when power mains ■ automatically stop working and standby power automatically reset ■ Timing washing lines (can be set time), each finished sample purge line (settable switch) operation more comfortable: ■ equipped with imported 7 million color TFT 7-inch color touch screen, in English Traditional three kinds of interface language, interchangeable. ■ original with high quality micro industrial printers (settable switch) ■ time to do like (can set the time), support for remote boot make sure that things like: ■ with RS232 interface (RS485 interface converter, open communications protocol), meet the digital ■ networking requirements with 4-20mA analog output (20mA corresponding adjustable range), can be easily networked YJ-COD2 type COD online monitor application: Widely used in waste water treatment, clean water, circulating water, boiler water systems as well as electronic, field plating process, printing and dyeing, chemical, food, pharmaceutical, surface water systems in remote monitoring and pollution emissions and other environmental monitoring applications such powerful features.
