Centec Carbotec TR-PT

The CARBOTEC TR-PT is the ideal choice for the continuous monitoring of dissolved carbon dioxide levels in liquids. This instrument is meticulously designed to meet the demands of applications requiring maximum sensitivity and the highest level of accuracy. It is user-friendly and requires minimal maintenance.

Here's how the CARBOTEC TR-PT operates: The carbonated liquid under examination flows through the sensor head, also known as the measurement chamber. Multiple times per minute, the chamber is sealed, and its volume rapidly expands. This expansion generates a gas phase within the chamber. The substantial difference in partial pressure of CO2 between the liquid sample in the chamber and the gas phase prompts the carbon dioxide to move out of the sample and into the gas phase. This fundamental scientific principle is governed by Henry's Law. Within seconds, pressure equilibrium is established within the measurement chamber. The pressure at equilibrium corresponds to the CO2 content in the sample. The determination of the CO2 content relies on the measurement of pressure and temperature within the chamber.
