EDK 7100-P portable ozone gas analyzer
Overview
EDK 7100p ozone gas analyzer of ETG Italy, based on Beer-Lambert Law for ultraviolet light sources. Ultraviolet light at the wavelength of 254nm is absorbed by O3 when passing through the sample chamber of O3 gas. The absorption value and the concentration of O3 follows Beer-Lambert Law. By measuring the change value of ultraviolet light signal before and after absorption and comparing with the reference light source, the concentration value of O3 was analyzed.
Characteristics
Second level response, quick measurement
Optional multipoint sampling (MPS)
Modular design, simple maintenance
High stability optical path system and UV light source
Long endurance operation(continuously for 12 hours)
Double light path nondispersive ultraviolet absorption spectroscopy
Good repeatability (2%), high reliability (IP54)
Automatic temperature and pressure compensation (built-in pressure and temperature sensor)
Simple operation (5.7 "touch screen), compact and portable(suitcase)
Application
Ozone monitoring and analysis in the process of scientific research and production of environmental gas, pollution source, meteorological climate, ozone preparation, petrochemical raw material gas, rubber material, papermaking, textile, pharmaceutical, essence and flavor, water treatment, medical and health, food and other industries
