Handheld Oxygen Analyzers

SD1X00 Series Portable Dissolved Oxygen Analyzer

Xincen Technology SH1100/SH1200/SH1300b series portable oxygen analyzer adopts high-precision polarographic dissolved oxygen electrode with advanced detection circuit, designed for trace-level gas oxygen and dissolved oxygen measurement. DO resolution up to 0.01 μg/L (ppb) and detection accuracy up to 0.10 μg/L (ppb), gas oxygen accuracy up to 0.001%. Ideal for trace dissolved oxygen analysis in nuclear power, thermal power and waste heat boiler deoxygenated water, trace oxygen monitoring in semiconductor chip packaging and high-end PCB ultrapure water processes, as well as drinking water, aquaculture, wastewater and industrial water. The handheld design weighs only 300g with high-brightness backlit screen and magnetic adsorption function; digital, analog and corrosion-resistant electrodes optional; ready to measure on power-on without prolonged polarization; electrode resistant to corrosion, high humidity and organic mixed gases; ultra-low power consumption with 4 AA batteries providing up to 3000 hours; IP65 protection. A professional choice for on-site trace oxygen measurement.
