pH / Conductivity / Temperature
• PTTestr 35 (Eutech PCTEST35-01X441505 / Oakton 35425-05)
pH / Total Dissolved Solids / Temperature
• PCSTestr 35 (Eutech PCSTEST35-01X441506 / Oakton 35425-10)
pH / Conductivity / Total Dissolved Solids / Salinity / Temperature

Getting Started:

Your instrument has been factory calibrated and usually works well out of the box. However, after
best accuracy.
Your Testr begins in the measuring mode that was previously used. Just prior to measurement or
when switching modes, you will see the setting associated with each parameter i.e.) pH (buffer

sensor (pictured here) in warm tap water or pH buffer for 10 minutes or so. A
brief rinse with deionized (DI) water is OK, but avoid soaking or storing in
