Description
HM Digital Hydromaster HM200 Portable - pH TDS EC Temp Meter
The HM Digital HydroMaster HM200 allows you to keep track of the water quality used in gardening in a more portable package.
Designed for hydroponic growers, the HydroMaster HM200 allows you to continuously track pH, EC, TDS, salinity, and temperature levels in your water tanks so that your plants grow on the best medium.
Non-hydroponic growers will benefit from the HydroMaster HM200, as you can use this device in laboratory applications.
Features

Programmable Sensors
The HydroMaster HM200 allows you to set alerts when parameters go below or above the limit you set the sensors to detect.
