HM Digital Pro COM-300 pH TDS EC Temp Meter

Description   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. Features Variable Applications The COM-300 allows you to test water samples used in different applications, such as hydroponics, water treatment, and laboratory usage. Easy to Read The COM-300 features a large LCD that makes checking the meter easier, despite its compact form factor. Energy-Saving To help you save on power, the COM-300 shuts down after being idle. Battery-operated You can run the COM-300 with a pair of AAA batteries.
