Water analyzer W501-DWP10.1

aluminumhydrogenhydrogen peroxide

The Online Hydrogen Peroxide Analyzer consists of an instrument with LCD display and a German-made WP10.1 sensor with special osmotic membrane technology, resisting chemical interference (especially surfactants) and reducing pH dependence, unaffected by water quality, it offers fast response, stable performance, low cost, low maintenance, and reliable data. Applied mainly in power plants, petrochemical, metallurgy, mining, paper, bio-fermentation, pharmacy industry, food/beverage, water treatment, aquaculture fields etc. Working Principle The entire measurement system mainly consists of two parts: the instrument W501 and the WP10.1 H2O2 sensor. The instrument displays the hydrogen peroxide value (main measured value), the pH value of the aqueous solution (pH electrode needs to be selected optionally), and the working status. It outputs signals such as analog, digital, and switch signals. The sensor is of the original imported RG brand from Germany and works on the principle of the film-covered three (dual) - electrode constant current method, with the characteristics of anti-interference and anti-pollution. The sensor is not restricted by water quality conditions and can be applied in various industries. Application Fields Power plants, petrochemical industry, metallurgy and electronics, mining industry, papermaking industry, biological fermentation process, medicine, food and beverage, environmental water treatment, aquaculture, and various other industries. Functional Features - Dual-channel access, allowing configuration according to requirements. - Enables plug-and-play of sensors, making electrode installation and replacement quick and convenient. - Features a simple-to-operate interface, which reduces the likelihood of operational errors and ensures reliable results. - Visual operation on the LCD screen, with a rich and comprehensive interface content. - Equipped with multiple data output methods, such as 4-20mA and MODBUS RS485. - The controller supports wall-mounting / panel-mounting / pipe-clip mounting. - Crafted from aluminum alloy, it offers high strength, oxidation resistance, and corrosion resistance, enhancing its texture and market attractiveness.
