Quantek 902P oxygen and carbon dioxide analyzer

Description

Quantek 902P oxygen/carbon diaoxide analyzer.  Was used a few hours in 2014 for a prototype project which was not discontinued and has been in storage since then.  Original invoice attached in images.  It will need a trip to Quantek for calibration and probably replaced t of the O2 sensor for an estimated 0 per a recent email from Quantek.  I fully believe this device will function perfectly with a small additional investment and serve you very with precision and reliability.
Manual is available as well as technical support from Quantek as this is still in current production.
