Quantek QU-901 Headspace Oxygen Analyzer

Quantek QU-901 Headspace Oxygen Analyzer เครื่องวิเคราะห์ออกซิเจนในบรรจุภัณฑ์

Oxgygen Analyzer for Food Packagers
Built-in pump & Sensor (Sampling pump: Internal, with adjustable timer)
Easy to Use with Rechargeable Batteries
Calibrates with room air
The expected electrochemical sensor life is typically 5 years, unlike other analyzers with an electrochemical sensor that last 1-2 years.
The sensor is unaffected by high levels of background gases such as nitrogen or carbon dioxide, and unaffected by trace hydrocarbons.
