PXS-CO2 type water carbon dioxide concentration meter

1、 Overview of Carbon Dioxide Concentration Meter in Water

The PXS-pCO2 water carbon dioxide concentration meter is designed to measure the carbon dioxide content in aqueous solutions. It is suitable for quality monitoring of power plant water (such as steam, condensate, boiler feedwater, etc.) and can also be used in higher education institutions, scientific research structures, food production institutions, and other departments to measure the carbon dioxide concentration in natural water, industrial products, industrial wastewater, and other water.

2、 Characteristics of Carbon Dioxide Detector in Water

The PXS-CO2 carbon dioxide concentration meter adopts microcontroller technology, making operation simple and convenient, and the digital display intuitive and correct.

The instrument has manual temperature compensation and automatic temperature compensation functions (when the temperature electrode is connected, the instrument enters automatic temperature compensation and displays the current temperature; when the temperature electrode is not connected, the instrument enters manual temperature compensation and displays the manual temperature setting value). The temperature electrode is an optional key, and if the user needs it, they need to specify it when placing an order.

In addition to displaying pCO2 values, the instrument also has the function of displaying carbon dioxide concentration values [CO2].

The instrument has a beautiful and lightweight appearance.
