Phasing out portable 311 series and introduction new portable oxygen analyzer

Did you purchase a portable oxygen analyzer from the 311 series of the brand Teledyne Analytical Instruments in the past? Then please pay attention to the following message: 

This model has been taken out of production since 2018. This means that we cannot guarantee you that we are able to supply parts for the 311 series or repare it for you. We count on your comprehension in this matter. 

In 2014, Teledyne expanded its range of portable oxygen analyzers with the 3110 series. This digital meter was already developed in 2014 to eventually replace the analogue 311 series.

Improvements of the 3110 compared to the 311 series

First of all, the 3110 is a digital system, making it even easier to operate and calibrate; the correct scale is automatically selected and data is logged via a digital output. The 3110 is also supplied as standard in a robust carrying case. All conditions for certification are also met, such as an ATEX certificate. Optionally, the 3110 can be equipped with a sampling system consisting of a filter, volume control, pipes and connections mounted on the 3110.
