Ohaus Starter ST300D-G Portable DO (Dissolved Oxygen) Meter Kit

Ohaus Starter ST300D-G Portable DO Meter Kit - Product Description

Instant-On Galvanic Technology for Rapid DO Measurement

The Ohaus Starter 300D DO Portable Meter brings over a century of OHAUS measurement precision to portable dissolved oxygen analysis, offering convenience, reliability, and durability in one compact design that adapts to wherever your work takes you. Featuring an advanced galvanic electrode that can be used immediately after being powered on, the ST300D eliminates the typical warm-up wait time associated with traditional dissolved oxygen meters, allowing you to begin testing instantly and maximize productivity in the field. This innovative electrode technology provides accurate DO measurements across a comprehensive range from 0.00 to 45.0 mg/L (ppm) and 0 to 400% saturation with ±1% accuracy, making it suitable for a wide variety of aquatic environments from oxygen-depleted waters to supersaturated conditions. The durable IP54-rated ABS housing protects the meter from dust and water splashes during field operations, while the included wrist strap and meter stand ensure secure handling during sample collection. Powered by four standard AAA batteries that deliver an impressive 250 hours of continuous operation, the ST300D provides extended field performance without the interruption of frequent battery changes.

User-Friendly Design with Intelligent Temperature Compensation

Engineered for straightforward operation without compromising measurement quality, the ST300D combines a simple calibration process with automatic temperature compensation to deliver fast, accurate results in real-world field conditions. The integrated 30 KΩ NTC temperature sensor monitors sample temperature from 0 to 50°C with ±0.3°C accuracy, automatically adjusting DO readings to compensate for temperature effects and ensuring reliable measurements across varying environmental conditions. The clear LCD display presents all measurement data including DO concentration in multiple units (mg/L, ppm, or % saturation) and temperature in an easy-to-read format, allowing operators to quickly assess water quality parameters at a glance. For efficient data management and quality control verification, the 30-measurement memory library stores critical readings for future reference and regulatory documentation, while the convenient one-touch recall function allows users to instantly access the last calibration data to verify meter performance and maintain measurement confidence throughout extended field sessions. The two-point calibration capability ensures optimal accuracy across your specific operating range, making the ST300D an ideal choice for environmental monitoring, aquaculture management, wastewater treatment, stream studies, and educational applications.
