DSC205 Dissolved CO2 Sensor In Water CO2 analyzer For Aquaculture
Overview
DS205 is a gas detection module based on the NDIR infrared
absorption principle, which is suitable for detecting the concentration of carbon dioxide in
aqueous solution. DS205 adopts optical cavity, imported light source and dual-channel
detector to achieve spatial dual optical path reference compensation. DS205 has a good
selection Optional, no oxygen dependence, long life.
DS205 has UART, 485, IIC digital output, analog voltage output and
PWM frequency output mode, which is convenient for customers to choose
applications; DS205 provides zero calibration, sensitivity calibration and clean air calibration
commands, and provides customers with a manually calibrated MCDL pin, which is convenient
for customers Relative zero calibration of the sensor module when using outdoor
free flowing clean air. DS205 adopts convection diffusion
ventilation method and protective cover, which can not only
accelerate the gas convection diffusion speed, but also protect the
ventilation membrane. Detachable structure, easy to clean the
sensor outer tube.
DS205's unique waterproof structure can be removed for easy maintenance and
cleaning. DS205 can be used to measure the concentration of dissolved CO2 gas in water,
and it can also be used to monitor the concentration of CO2 in high temperature and
high humidityenvironments.
