Starter 300 Ohaus ST300C-G Conductivity

The Starter 300 Ohaus ST300C-G Conductivity is a compact, handheld instrument engineered to deliver precise and reliable conductivity, total dissolved solids (TDS), and temperature measurements. Designed for professionals who need dependable performance both in the laboratory and in the field, this device combines accuracy, convenience, and durability in one easy-to-use package.

Key Features

The ST300C-G offers a wide measurement range from 0.01 μS/cm to 199.9 mS/cm for conductivity and 0.1 mg/L to 199.9 g/L for TDS, covering applications from ultrapure water testing to high-salinity solutions. It also measures temperatures between 0°C and 100°C, ensuring accurate analysis across a variety of environments. The instrument achieves ±0.5% accuracy in conductivity readings and ±0.3°C in temperature, making it ideal for demanding analytical and industrial applications.

Equipped with the Ohaus STCON3 electrode (included), the meter ensures fast response, excellent sensitivity, and stable long-term performance. Its LCD display provides clear, easy-to-read results, while the intuitive one-point calibration process allows quick setup and minimal maintenance. In addition, the automatic temperature compensation (ATC) feature continuously adjusts readings to account for temperature changes, ensuring consistent accuracy in every measurement.

Powered by four AAA (LR03) batteries, the ST300C-G offers up to 250 hours of continuous operation, providing long-lasting reliability in fieldwork and laboratory use. Weighing only 0.35 lb (0.16 kg) and measuring 6.69 × 1.38 × 3.54 in (170 × 35 × 90 mm), the device is lightweight, ergonomic, and highly portable—perfect for on-the-go testing and routine inspections.
