Application Notes

Here's how some of our customers used this product.

Detecting Trace Oxygen in Packaging

The Background: The customer, a medical device manufacturer, packages their product in nitrogen purged bags and randomly test this packaging to ensure that no oxygen has seeped into it. They need to replace their previous oxygen detector, a Bacharach Oxor III.

The Problem: The Oxor III is no longer available so the customer must find an affordable, highly portable replacement that utilizes a probe assembly which can be inserted into the packaging for testing.

The Solution: Since the customer had confidence in Bacharach products they selected the Bacharach Fyrite InTech with the O2 sensor only. Though it's a combustion analyzer, it offers accurate oxygen measurements in a portable unit and uses a probe assembly.
