QSE-303 Quik Salinity Testing System

Part of Quest’s Qleen-Line Products

Meets the criteria defined in the Pasteurized Milk Ordinance, PMO, for testing the holding time on a pasteurization system.

Reliably & Accurately Test Your Pasteurization Holding Time!

QSE-303 Meter
The quest Qleen Start Valve eliminates the need for a start conductivity probe, providing more accurate, reliable, and consistent results.

How It Works:
A technician opens the valve. Upon opening, the valve releases a pressurized salt solution, starts the test, and begins keeping time. The test concludes when the salt solution is detected by the probe at the end of the holding tube. Each test is performed individually and the results are recorded by the technician.

This system has consistently performed more quickly and reliably than the leading competitor’s system.
