Oakton Waterproof Multiparameter
Testr™ 35-Series Pocket Meters
®
pH Testers
Save time and money—like three meters in one!
P
––Parameters include pH, conductivity, TDS, salinity, and temperature
––Compatible with a wide range of samples
––Long-life pH electrode and stainless steel pin-style conductivity sensor
––Save money by replacing sensor module
Advanced features include up to 5 point pH calibration with NIST or USA autobuffer recognition,
auto-shutoff, user-adjustable temperature coefficient, self-adjusting TDS and salinity factor,
and low-battery indicator. The IP67-rated housing floats if accidentally dropped into water.

Oakton® Waterproof pH Spear
Virtually impossible to clog
––Electrode junction is 200 times larger than standard electrodes
––Ideal for soft solids and semisolid materials like meats, cheeses, and fruit
Spear tip fits into
microcentrifuge tubes.
––Easily determine pH in test tubes and other narrow containers
The unique junction design provides increased electrolyte flow, resulting in greater contact
between sample and reference, ensuring fast, stable readings. The double-junction design
offers enhanced performance. Additional features include a hold function, auto-off function,
self-diagnostic error messages, and a three-segment battery-life indicator.
