Description

Chemicals High Tolerance Two-Electrode System Hydrogen Peroxide Sensor For All Water Treatment

The two-electrode system membrane hydrogen peroxide sensor WP10 has the following features and advantages, making it an excellent performer in the field of water treatment:

Features

Mechanically strong membrane system

The sensor adopts a high-strength membrane system design, which can operate stably in harsh environments and effectively prevent damage.

Surfactant tolerance

It has high tolerance to surfactants (such as detergents or chemical reagents) and is suitable for a variety of water quality conditions.

High tolerance to chemicals

It can resist the influence of a variety of chemicals (including strong oxidants or other corrosive substances) to ensure long-term stability.

Applicable temperature range

The working water temperature can reach up to 45℃, which meets most industrial water treatment needs.

Multiple optional ranges

Three ranges are available: 0200 ppm, 02000 ppm, and 0~20000 ppm, which meet different needs from trace detection to high concentration detection.

Advantages

Accurate measurement

Using a two-electrode system, it has high sensitivity and accuracy and can quickly respond to changes in hydrogen peroxide concentration.
Low maintenance requirements

Durable design and stable operation reduce maintenance frequency and cost.

Widely used

Applicable to various water treatment processes, including drinking water, industrial wastewater, sewage and circulating cooling water.

Easy to operate

Modular design and user-friendly interface for easy installation and use.

High stability

Not affected by water flow fluctuations, capable of long-term continuous operation, reducing the risk of instrument drift and data errors.

Two-electrode system, used in all water treatment, mechanically strong membrane system, resistant to surfactants, high resistance to chemicals, maximum water temperature: 45°C, optional range 0~200/2000/20000 ppm

Information about the measuring range

The actual slope of a sensor can vary production-related between 65% and 150% of the nominal slope

Note: With a slope > 100% the measuring range is reduced accordingly.

(Ex.: 150% slope → 67% of the specified measuring range)

(no ice crystals in the measuring water)

Ambient temperature: 0 … +55 °C

Temperature compensation

Automatically, by an integrated temperature sensor Response time t90 = approx. 8 min.

Max. change in temperature: 5 °C per hour, sudden temperature changes must be avoided

Max. allowed working pressure
