Ohaus Starter 300 pH Portable Meter - Product Description

Reliable Precision in a Compact, Field-Ready Design

The Ohaus Starter 300 pH Portable Meter brings over a century of OHAUS measurement expertise to portable water analysis, delivering convenience, reliability, and durability in one compact design that goes wherever your work takes you. This practical pH meter is engineered for professionals who need accurate, dependable measurements in field and laboratory environments without the complexity of advanced systems. Featuring intelligent auto buffer recognition with four different buffer groups, the ST300 simplifies the calibration process and helps users avoid common errors that can compromise measurement accuracy. The durable IP54-rated ABS housing protects the meter from dust and water splashes, while the included wrist strap and meter stand provide secure handling during field operations. Powered by four AAA batteries that deliver an exceptional 500 hours of continuous operation, this meter ensures you have the power you need for extended field campaigns without frequent battery changes.

Simple Operation with Smart Features for Efficient Workflow

Designed with user-friendliness at its core, the ST300 combines a straightforward calibration process with automatic temperature compensation to deliver fast, accurate results every time. The clear LCD display provides easy-to-read measurements of pH (0.00 to 14.00), oxidation-reduction potential/ORP (-1999 to 1999 mV), and temperature (0 to 100°C) with high accuracy specifications of ±0.01 pH, ±1 mV, and ±0.5°C. The built-in 30 KΩ NTC temperature sensor enables precise automatic temperature compensation across the full measurement range, ensuring reliable results regardless of sample temperature variations. For efficient data management, the 30-measurement memory library stores critical data for future reference and quality control documentation, while one-touch recall of the last calibration data allows users to quickly verify meter performance and maintain measurement confidence in the field. The three-point calibration capability provides flexibility to optimize accuracy across your specific pH range of interest, making the ST300 an ideal choice for environmental monitoring, aquaculture, wastewater analysis, agricultural testing, and educational applications.
