Bluelab METCOM Combo Meter Product Review

The Bluelab METCOM Combo Meter is an excellent portable tool that takes measurements of pH, conductivity, and temperature within a solution.

This is important because the correct pH, conductivity and temperature levels of nutrient solution are important for healthy and successful growth.

Are you experiencing issues with yellow leaves and slow growth? The Bluelab Combo Meter will soon tell you if the vital parameters are within the plant’s requirements.

The Bluelab Combo Meter has two probes, a Bluelab pH Probe and a Bluelab Conductivity/Temperature Probe.

To take a reading, simply place both probes both into the solution and your reading will be displayed on the screen.

The Bluelab Combo Meter doesn’t require a power supply to operate, therefore readings can be taken anywhere to manage your crop’s requirements.

This pH probe’s calibration instructions are supplied on the back of the meter.

After 30 days, the calibration indicators will disappear which is useful because it lets you know that calibration is due.
