DOS-1703 Portable Dissolved Oxygen Meter for Ultra-low Power Microcontroller Measurement and Control Video Website： https://www.boquinstrument.com/ BOQU DOS-1703 portable dissolved oxygen meter is outstanding for ultra-low power microcontroller measurement and control, low power consumption, high reliability, intelligent measurement, using polarographic measurements, without changing the oxygen membrane. Having reliable, easy (one-hand operation) operation, etc.; the instrument can display dissolved oxygen concentration in two kinds of measurement results indicates, mg/L (ppm) and the oxygen saturation percentage (% ), in addition, measure the temperature of the measured medium simultaneously. Technical indexes of handheld DO Meter Measuring range:DO 0.00--20.0mg/L,.0--200% Temp 0…60℃ （ATC/MTC） Atmosphere 300--1100hPa Resolution:DO 0.01mg/L,0.1mg/L(ATC）,0.1%/1%(ATC） Temp 0.1℃ Atmosphere 1hPa #dometer #dissolvedoxygenmeter #dissolvedoxygenanalyzer Whatsapp：86-15000087545 E-MAIL：[email protected]

BOQU Industrial Online Desulfurization pH Electrode CPH-809X Video Website: https://www.boquinstrument.com/ It's good to absorb the SO2 in high pH slurry environment,otherwise it's easy of precipitation of Ca2+ in low ph value, which are opposite each other. Therefore, in the limestone-gypsum wet desulfurization system, the pH value of the circulating slurry is an important parameter which will effect the performance of the desulfurization system. When the pH value is 6, the sulfur dioxide absorption effect is the best, but at this time, it's easy for scaling and clogging. The low pH value is beneficial to the oxidation of calcium sulfite, the solubility of limestone is increased, but the absorption of sulfur dioxide is inhibited, and the desulfurization efficiency is much reduced. When pH=4, the absorption of sulfur dioxide is almost impossible, and the absorption liquid is acidic, The equipment also will be corrosived. So BOQU Instrument R&D department do much test.The test results show that the increase of circulating slurry pH value is beneficial to the desulfurization rate. The limestone content in the slurry also increases; after the pH value of the circulating tank slurry is greater than 6.0, the limestone content in the slurry increases sharply, and the desulfurization rate decreases significantly after the pH value of the circulating tank slurry is less than 4.8; the combined circulating slurry pH value desulfurization rate and limestone The reasonable operating range of the pH value of the slurry in the circulating tank is 4.8-6.0. #phorpsensor #digitalphsensor #phmetersensor E-MAIL：[email protected] Whatsapp：86-15000087545

??? what's the Digital Conductivity Meter ? 1)Extremely quickly and precision digital conductivity sensor 2)The conductivity sensor directly with RS485 Modbus, the calibration data can be stored in sensor, user can directly use it at site, no re-calibration. 3) It's suitable for harsh application and free-maintenance, save cost. 4) the conductivity sensor is for 0.01,0.1,1.0 and 10.0 5)The Digital Conductivity Meter can show conductivity, TDS, Salinity, Resistivity and temperature. 6)Conductivity transmitter also provides provide two ways of 4-20mA output, RS485 Modbus, 3 relays 7)DDG-2080S Conductivity controller With data recording function, user easy to check history data and history curve. #salinitymeter #conductivitymeter #onlineconductivitymeter Website: https://www.boquinstrument.com/ Whatsapp：86-15000087545 E-MAIL：[email protected]

The sewage of the pig farm mainly includes pig urine, part of pig manure and pig house washing water, which is a high-concentration organic sewage, and has a large suspended matter and ammonia nitrogen content. After the untreated sewage enters the natural water body, the suspended solids, organic matter and microbial content in the water are increased, and the physical, chemical and bio-community composition of the water body is changed, and the water quality is deteriorated. Sewage also contains a large number of pathogenic microorganisms that will spread through water bodies or through aquatic animals and plants, endangering human and animal health. Therefore, the sewage treatment system of this project adopts the process of solid-liquid separation pretreatment + anaerobic treatment + aerobic treatment + advanced treatment.
