Model:
  • Selective measurement of total package oxygen from cans and bottles
  • Results in down to less than four minutes
  • Self-cleaning and minimum maintenance
  • Modular extensions for up to 50 industry specific measurement parameters
  • O2 ingress detection at the source for consistent filler performance
  • One-touch measurement and automatic cleaning
  • Modular integration for analysis of up to 50 parameters
  • Optional 360° status light for monitoring measurement progress
  • Selective CO2 analysis upgrade for expanded requirements 

TPO 3001 and 5001 precisely determine total oxygen in beverages by selectively measuring headspace and dissolved oxygen directly from cans, glass, or PET bottles. Designed for use right at the filling line, these advanced total package oxygen (TPO) meters ensure consistent filler performance and protect your product’s shelf life, taste, and appearance. Paired with Anton Paar’s proven selective CO₂ measurement method, the modular TPO meter series delivers fast, accurate results and seamlessly integrates into the most powerful multiparameter systems on the market.

Key features

Pinpoint oxygen ingress where it occurs

The TPO meter series brings laboratory accuracy directly to the production line, delivering precise, repeatable TPO results – including both headspace and dissolved oxygen – within minutes. By identifying where oxygen ingress occurs, it helps maintain consistent filler performance and minimize production waste. A robust IPX3-protected design ensures reliable operation even in harsh environments. For unmatched accuracy, the TPO meter series can be equipped with optional selective CO2 measurement, based on Anton Paar’s trusted principle refined over more than 20 years.

Fast, automated, and intelligent self-monitoring

Designed for efficiency and ease of use, the TPO meter series combines speed, automation, and intelligent control for consistent results at the filler. With one-touch measurement functionality, it delivers TPO results in down to four minutes. Fully automated sensor cleaning after every run and continuous self-monitoring of key handling parameters – such as package positioning and gas and water supply status – ensure reliable, error-free performance. Operators receive instant on-screen guidance when deviations occur, and the optional 360° status light tracks measurements and instrument condition from any angle.

Effortless comparison of CO₂ results

CO₂ concentration values are automatically compensated to a user-defined reference temperature to ensure directly comparable and reproducible results. This intelligent function eliminates the need to manually adjust  or regulate sample temperature  before measurement, saving valuable time and minimizing operator effort while maintaining consistent precision and reliability.

All your beverage parameters: Connected, traceable, digital

Developed by the market leader in multiparameter beverage analysis, the TPO meter series integrates seamlessly into the industry’s most powerful multiparameter measurement platform, enabling the analysis of over 50 product-release parameters from a single package. Full compatibility with AP Connect, Anton Paar’s lab execution system, ensures efficient digital data handling, providing traceable, organized, and easily accessible measurement results across production and laboratory networks.
