Description

  1. Graphite Conductivity Electrode: The use of a graphite conductivity electrode is a notable feature, as it offers greater accuracy by preventing contamination from salt deposits that can affect readings.

  2. Exposed Temperature Sensor: The exposed temperature sensor ensures fast response times and accurate temperature-compensated readings, which is essential for accurate pH and EC measurements.

  3. Large Dual-Level LCD: The large, easy-to-read LCD display allows users to easily view the measured values, making the device user-friendly.

  4. Automatic Shut-off: The automatic shut-off feature helps conserve battery life by turning off the device after a period of non-use, extending the battery's longevity.

  5. pH Electrode with Extendable Cloth Junction: The extendable cloth junction in the pH electrode enhances its lifespan and ease of maintenance. Additionally, the fact that replacement electrodes are available separately is beneficial for long-term use.

  6. Sturdy Snap-in Connector: The snap-in connector is designed for durability and reliability, minimizing the risk of bending or breaking pins.

  7. Accessories Included: The Combo Tester comes with essential accessories such as a protective cap, electrode removal tool, batteries, and instructions, ensuring users have what they need for successful operation.

  8. Battery Error Prevention System (BEPS): The BEPS feature prevents battery-related errors and extends the battery life, contributing to the overall usability of the device.

  9. Temperature Compensation and EC/TDS Conversion: The device compensates for temperature effects on pH and EC readings and allows users to select the EC/TDS conversion factor based on their specific needs.

  10. Measurement Ranges: The provided measurement ranges cover a wide spectrum, allowing users to measure various concentrations and pH levels relevant to soil and water solutions.

These features collectively make the Combo Tester a versatile tool for professionals and enthusiasts involved in agriculture, hydroponics, and other applications where precise nutrient management is essential for optimal plant growth. Users can benefit from the accurate measurements, ease of use, and portability offered by these innovative solutions from Hanna Instruments.
