CO2 Sensor InPro5500i/Var. Type N

In-Line CO2 Measurement in Beverages. The InPro 5500i Varivent is a thermal conductivity CO2 sensor that is optimal for monitoring carbonation levels for beer and soft drink quality control. Its ISM technology simplifies handling and reduces sensor lifetime costs.

Maintain Beverage Quality Control

This CO2 sensor helps ensure final products meet your standards. It provides reliable, accurate CO2 measurements in carbonated beverages and beer.

Durable Performance and Easy Handling

The InPro 5500i has no moving parts, helping to prevent downtime. The simplified membrane cap design allows for fast maintenance.

Intelligent Design and Diagnostics

The CO2 sensor has built-in protection during CIP/SIP, and its predictive diagnostics protect the integrity of your m

Easy to Handle and Maintain

This CO2 sensor uses a membrane body concept to dramatically limit maintenance time. The inner body, a pH electrode, can easily be replaced on site.
