Hydrogen peroxide, humidity and temperature probe HPP270 series probe HPP271 and HPP272. It is designed for harsh hydrogen peroxide biological disinfection environments where repeated, stable and accurate measurements are required. The HPP270 series probes are suitable for a variety of applications, such as isolators, material transfer Windows and indoor biological purification.The new basic probe option HPP271 is only used to measure hydrogen peroxide vapor concentration, while the new high quality option HPP272 provides the following main parameters to be measured during biological purification: hydrogen peroxide vapor concentration, temperature, and humidity (relative mix saturation and relative humidity). In addition, dew point and steam pressure can be measured.

• ? Good stability and repeatability
• ? Traceable calibration certificate
• ? Corrosion resistant stainless steel case (IP65)
• ? Compatible with Indigo output transmitter when needed

Main Advantages:

Accurate and reliable measurement

Smart measurement technology, including chemical cleaning features, helps maintain accuracy between calibrations in challenging hydrogen peroxide environments. Chemical removal eliminates possible contamination by rapidly heating the sensor. The PEROXCAP sensor used in the HPP270 series probes uses a heating design that prevents condensation from forming on the sensor. Thus, reliable measurements can be provided even under condensing conditions.

One instrument has 3 measuring parameters

In addition to hydrogen peroxide, the compact HPP272 probe also measures temperature and humidity (referring to relative humidity and relative saturation). Accurate hydrogen peroxide readings ppm were given throughout the biological purification cycle. Dew point and steam pressure can also be measured.

Compliance with regulatory requirements

The results of repeated measurement function can meet the requirements of local laws and regulations and regulatory authorities.
