HM Digital Pro COM-300 pH TDS EC Temp Meter

The HM Digital COM-300 allows you to keep track of the water quality used in gardening in a more portable package.

Designed for hydroponic growers, the COM-300 allows you to track pH, EC, TDS, salinity, and temperature levels in different applications so that your plants grow on the best medium.

Non-hydroponic growers will benefit from the COM-300, as you can use this device in laboratory applications.
