Dpstar is a leading supplier of environmental measurement sensors for temperature, relative humidity, pressure, dew point, CO2, and other environmental condition monitoring for industrial process application and research. Since the ’90s, we earned a reputation as a trusted partner to our clients through our commitment and dedication. We are an authorized distributor and supplier of measuring sensors solutions from renowned manufacturers Vaisala. Vaisala is a global leader in environmental and industrial measurement. Building on 80 years of experience, Vaisala provides observations for a better world. Vaisala is a reliable partner for customers around the world, offering a comprehensive range of innovative observation and measurement products and services.
The Vaisala PEROXCAP Hydrogen Peroxide, Humidity, and Temperature Probe HPP270 series probes are designed for demanding hydrogen peroxide bio-decontamination. The probes are ideal wherever repeatable, stable, and accurate measurement is essential and suitable for a variety of applications such as isolator, material transfer hatch, and room bio-decontamination. The basic probe option HPP271 is for measuring only H2O2 vapor concentration. The advanced HPP272 probe measures all relevant parameters during bio-decontamination processes, including hydrogen peroxide vapor, temperature, and humidity as relative saturation and relative humidity, dew point, and vapor pressure. The probes can be used as standalone devices, or with Vaisala Indigo transmitters: Indigo200 transmitters and Indigo520 transmitters. For easy-to-use access to configuration, calibration, and adjustment the probe can be connected to Vaisala Insight PC software.
