Benchtop Headspace Gas Monitoring of Individual Sealed Packs

The work horse of headspace gas analysers, for the accurate, fast analysis of O2 or O2/CO2 in the headspace of gas flushed packages. Using the latest Zirconia O2 sensor designed, built and tested by Dansensor and ideal for high volume testing. Robust and suitable for both the factory floor and laboratory use.

There are two versions available. For standard applications:

  • %O2 and %Balance – choose the Zirconia O2 version
  • %O2 and %CO2 and %Balance – choose Zirconia O2/CO2 version

For applications where alcohol, or carbon monoxide may be present, such as ground coffee, or some bakery and pharmaceutical products, an alternative electrochemical oxygen sensor is available:

  • %O2 and %Balance – choose the electrochemical O2 version
  • %O2 and %CO2 and %Balance – choose electrochemical O2/CO2 version

Operation Does not require an external computer, or tablet. Via the password protected 5″ touchscreen, the user can set up specific testing parameters & settings for each product, or group of products. Excellent traceability & result recall.

The Dansensor CheckMate 3 will hold up to 1000 products. The test results are date and time stamped. They will be subsequently logged in the internal memory, or can be exported via a LAN port, RS232, USB to Dansensor® CheckMate 3 PC software, or to Paperless QA software.

Advanced testing schemes requiring entry via an operator ID, batch number, production line and text input, are also selectable. A barcode scanner can be added, to speed up product and operator ID, if required.

A choice of different modes of operation can be selected to activate a test – automatic spot test, manual spot test, intermittent testing and continuous testing.

Sample volume size can be selected to a minimum of 3ml. This enables packages with minimum headspace, such as single portion and blister packs to be tested, using the small sample syringe kit.

Enhance operator safety and needle control in High Care Production by adding a SmartPen. Unique to the Dansensor CheckMate 3, the SmartPen has a retractable needle that is exposed only when the SmartPen is pushed on the test pack’s surface at the start of a test. It then retracts as the SmartPen is lifted off the sample pack.

Supplied with a five point calibration certificate, traceable to National Standards. The CheckMate 3 only requires recalibration and certification every 12 months, at the Tendring Pacific Service Centre. Easily arranged by taking one of our service contracts.

To help users get off to a confident start with their first CheckMate 3, we offer a low cost initial start up and training option, when purchased with the instrument.
