The HM Digital HydroMaster HM500 allows you to keep track of the water quality used in gardening.
Designed for hydroponic growers, the HydroMaster HM500 allows you to continuously track pH, EC, TDS, and temperature levels in your water tanks so that your plants grow on the best medium.
Non-hydroponic growers will benefit from the HydroMaster HM500, as you can use this device in laboratory applications.
The HydroMaster HM500 allows you to set alerts when parameters go below or above the limit you set the sensors to detect.
Need round-the-clock monitoring? The HydroMaster HM500 allows you to run the sensors for continuous usage so that you get alerted of any changes in your water system.
The HydroMaster HM500 allows you to store up to 20 measurement readings to help you look into trends and make any adjustments.
The HydroMaster HM500 features a large touchscreen that makes checking readings and navigating the interface more accessible.
To help you save on power, the HydroMaster HM500 shuts down after being idle for five minutes.
You can run the HydroMaster HM500 with its built-in rechargeable battery or an AC power source.
