Ohaus Starter ST20 Pocket pH Meter

The Ohaus Starter ST20 Pocket pH Meter offers 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 operated with just one hand, freeing up your other hand to handle samples.

Simple operation in a slim and portable design. The ST20 pocket pH meter provides 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 meter in its 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.
