3. Maintenance and Storage

  1. Rinse the electrode after use
  2. Turn off the device
  3. Store the electrode dry

What Is a Combo Measuring Device?

A combo pH and EC measuring device is a device designed specifically for measuring electrical conductivity (EC) and pH value in solutions. It is commonly used in areas such as agriculture, aquaculture, hydroponics, pond maintenance, as well as in the food industry and environmental monitoring.

These devices are typically compact, portable, and easy to use. They feature an electrode that is immersed in the solution to measure electrical conductivity and acidity.

Furthermore, they offer a variety of features, such as the ability to switch between Celsius and Fahrenheit or an automatic shut-off function. Ideally, the electrodes are replaceable to ensure a long lifespan.

To effectively utilize the combo measuring device for pH and EC, it is important to regularly clean and calibrate it. By using a combo pH and EC measuring device, you can easily and efficiently monitor these two properties of a solution and make targeted corrections with the appropriate acids, bases, and fertilizers.

What Are the Advantages of Such a Device for Hydroponics?

  1. Measurement of Both Key Parameters: With a combo measuring device, you can easily and quickly measure both pH and EC values without the need for two separate devices.
  2. Time Savings: Since both values can be measured quickly with one device, you save time that can be invested in other gardening tasks.
  3. Precise Measurements: Modern combo measuring devices are equipped with high-quality electrodes that enable very precise measurements.
  4. Easy Handling: The device is easy to use; you just need to immerse the electrode in the solution and read the values.
  5. Compact Size: Combo measuring devices are typically very compact and easy to transport.
  6. Robust Housing: Many combo measuring devices have a robust housing that protects against shocks and damage.
  7. Simple Calibration: Many combo measuring devices can be calibrated easily.
  8. Cost-Effective: Compared to the cost of two separate devices, combo measuring devices are generally cost-effective.
