Ohaus pH Meter


Accurate Results Anywhere and Anytime You Need Them

After more than a century of perfecting the art of measurement through our durable weighing products,
OHAUS precision is now available in a line of pen meters that provide accurate measurement of pH,
oxidation-reduction potential (ORP), conductivity, salinity, and total dissolved solids (TDS). Starter pen
meters are the economical option when you are simply looking for meters that will provide accurate
measurement with no restriction.

Standard Features Include:
• Simple Operation in a Slim and Portable Design—Starter pen meters provide what should
be expected of a small pen meter: simple, fast, straightforward, no-frills yet highly accurate
operation time and time again.
• Durably Constructed to Withstand Wear and Tear Resulting from Repetitive use—
With durable plastic housing, a protective cap that safeguards the sensor and an automatic
shutdown feature to preserve battery life, the Starter pen meters can endure consistent use
in rugged environments.
• Waterproof Housing Protects the Meters in their Working Environment—
Equipped with a wrist strap that helps to prevent unintentional dropping, Starter pen meters
are constructed with an IP67 waterproof design that can prevent water damage
when accidentally dropped into liquid.

Convenient pH Testing

Two models with varying resolution and accuracy, ST10 and ST20 offer a convenient way
to measure pH, or the relative acidity or alkalinity of a sample at a given temperature.
The pH pen meters can be completely operated with just one hand, freeing up your
other hand to handle samples.
