Get Better Accuracy. Oakton Instruments
offers the only TDS and conductivity
Testrs with ±1% full-scale accuracy.
This is the best accuracy available on
any pocket-sized Total Dissolved Solids
or Conductivity meter. This can make a
tangible difference for your application.
A Good Value. You also want a good
value when it comes to pocket-sized
instruments. Our drive for quality
and durability for our TDSTestrs and
ECTestrs is what inspires us to do
the extra things that may not even
be readily apparent. From our use
of custom thermoplastic housing
materials that offer superior chemical
and temperature durability, to our
self-diagnostic error messages to
help you immediately troubleshoot
calibrations, batteries and sensors.
Or, our application-specific micro-
processors that deliver superior
instrument reliability. All of these
things combine to give you a superior
product that delivers long-term value.
Lots of Options. Oakton Instruments
also gives you options offered by no
one else. We offer pocket-sized TDS
and EC Testrs that measure across
many ranges. We also offer a series
of testers that include built-in sample
cup sensors, and selectable °C/°F
temperature readout, a specially
designed tester for sodium chloride
solutions, and a series of traditional
“dip and read” meters.
More for Your Money. Better accuracy and
a higher-quality product featuring more
options. You get it all with the Oakton
TDSTestrs, ECTestrs, and SaltTestr.
