PPB DO

This PPB DO sensor is a high-precision trace dissolved oxygen probe designed for ppb-level ultra-low oxygen measurement. Different from conventional mg/L DO sensors, it adopts high-sensitivity electrochemical principle to accurately detect trace oxygen in high-purity water and boiler feed water.

This PPB DO sensor realizes stable measurement in ultra-low dissolved oxygen environment, with excellent anti-interference and long-term drift resistance. It integrates automatic temperature compensation and outputs standard RS485 MODBUS-RTU digital signal, easy to connect with analyzers, PLC and online water quality monitoring systems.

With fully sealed anti-corrosion structure, high pressure resistance and ultra-low consumption membrane design, it meets the strict water quality requirements in power, semiconductor and pharmaceutical industries.

It is widely used in thermal power plant boiler water, condensed water, semiconductor ultrapure water, pharmaceutical pure water and high-end water treatment systems.

PPB DO sensor and monitor are designed for trace dissolved oxygen measurement in ultra pure water.High-sensitivity electrochemical sensing, ultra-low range ppb detection, stable performance, built-in multi-compensation, RS485 / 4-20mA output.

PPB Dissolved Oxygen sensor is specially designed for ultra-low dissolved oxygen monitoring in high-purity water. It accurately measures trace DO at the ppb (μg/L) level, effectively solving the problem that conventional ppm-level DO analyzers cannot detect micro oxygen content stably and precisely. Widely applied in industries with strict water quality requirements, it ensures process safety and product quality.
