Stareter Pen Meter Ohaus ST20S Salinity Meter

The Stareter Pen Meter Ohaus ST20S Salinity Meter is a high-precision and portable instrument designed for accurate measurement of salinity and temperature in laboratory, aquaculture, and field applications. Because it features automatic temperature compensation (ATC) and rugged waterproof construction, this meter ensures stable, reliable, and fast readings even under challenging environmental conditions.

Features

• Dual Measurement Function: Measures both salinity (0.0–80.0 ppt) and temperature (0–99°C) for comprehensive solution analysis.

• High Accuracy and Resolution: Provides ±1.5% accuracy for salinity and ±0.5°C accuracy for temperature, with a fine resolution of 0.1 ppt.

• Automatic Temperature Compensation (ATC): Automatically corrects readings based on temperature changes, ensuring precise results in varying conditions.

• Single-Point Calibration: Allows quick, simple, and reliable calibration for consistent measurement performance.

• Clear LCD Display: The large, easy-to-read screen shows both salinity and temperature values simultaneously.

• Automatic Power-Off: Shuts down automatically after six minutes of inactivity to conserve battery life.

• Extended Battery Life: Operates up to 200 hours with four AG13 batteries (included), suitable for long-term field or lab use.

• Waterproof and Dustproof: With IP67 protection, the ST20S can withstand water immersion and harsh environments.

• Lightweight and Portable: Compact pen-style design (110 g) with a wrist strap for easy and safe handling during testing.
