When it comes to growing plants, one of the most important factors to consider is the pH level of the growing environment. pH levels that are too high or too low can negatively impact plant growth and even kill the plants. That’s why it’s crucial to have an accurate and reliable pH meter to monitor and adjust the pH levels as required. One such pH meter is the Bluelab METCOM Combo pH Meter and today we will talk about its importance in your hydroponic journey and also how you can calibrate it.
What is the Bluelab METCOM Combo pH Meter?
Let’s start with the very basics.
The Bluelab METCOM Combo pH Meter is a compact, handheld device that measures pH, conductivity, and temperature in hydroponic and soil-based growing systems. This meter is designed to be easy to use and provides accurate readings in just a few seconds.
With its large, easy-to-read display and simple user interface, the Bluelab METCOM Combo pH Meter is an excellent choice for any grower who wants to monitor their growing environment and ensure that their plants are growing in the right conditions.

How Does the Bluelab METCOM Combo pH Meter Work?
If you are a science/technical student, then you might already know.
The Bluelab METCOM Combo pH Meter uses an electrode (as shown in the picture below) that is dipped into the growing solution. The electrode measures the pH and conductivity of the solution and sends this information to the meter.
In the above picture, there are two probes, left one for measuring pH and the right one for measuring EC or conductivity of the nutrient solution.
The meter then displays the pH level, conductivity, and temperature on its large, easy-to-read display. The meter also has a built-in temperature compensation feature that adjusts the readings to account for temperature changes.

Why is Accurate pH Measurement Important for Plant Growth in Hydroponics?
pH levels play a crucial role in plant growth and can greatly impact how well plants absorb nutrients. If the pH level is too high or too low, the plant may not be able to absorb all of the nutrients it needs to grow.
This can result in stunted growth, yellowing leaves, and even death. By monitoring the pH levels in your growing environment, you can ensure that your plants are growing in the right conditions and getting all the nutrients they need to thrive.
How to Calibrate the Bluelab METCOM Combo pH Meter
Calibrating the Bluelab METCOM Combo pH Meter is easy and can be done in just a few simple steps. You will need to prepare a pH 7.0 buffer solution and a pH 4.0 buffer solution, which can be purchased from hydroponic supply stores or online. Simply follow these steps:
- Turn on the meter and make sure that it is in calibration mode showing “CAL” on screen.
- Dip the electrode into the pH 7.0 buffer solution and wait for a few seconds until the meter stabilizes and displays a pH reading.
- If the reading is not exactly 7.0, adjust it using the “CAL” button on the meter.
- Rinse the electrode with distilled water and then dip it into the pH 4.0 buffer solution. Wait for a few seconds until the meter stabilizes and displays a pH reading.
- If the reading is not exactly 4.0, adjust it using the “CAL” button on the meter.
- Rinse the electrode with distilled water and store the meter in a clean, dry place.
Finally, you should test the meter to make sure that it is giving accurate readings. You can do this by measuring the pH of a known solution or by comparing the readings to another pH meter. If the readings are inaccurate, you may need to recalibrate the meter.
In conclusion, calibrating your Bluelab Combo pH Meter is a simple and straightforward process that will ensure that you are getting accurate readings. By following the steps that I told, you can ensure that your plants are growing in the right environment and that your pH meter is functioning correctly.
So take some time to calibrate your meter and ensure you get the most out of it. Happy growing!
