The water hardness meter allows you to check the level of water contamination with inorganic substances. The meter is calibrated in "ppm" - parts per million, which is the most popular method in the world for determining the amount of chemical compound particles dissolved in water. The less contaminated the water is, the lower its electrical conductivity will be. Raw, unfiltered water can have a rating of up to 200 PPM or higher.

The EC conductivity of water can be considered as an indicator of its salt content; waters containing few ions have low electrical conductivity, while, for example, seawater has very high conductivity. The commonly used unit of water conductivity is μS/cm (= micro-Siemens/cm). Freshwater or lake water should have a conductivity between 300 and 1200 μS/cm.

• The controller is characterized by high measurement accuracy. 
• The measurement result is read on a clear LCD screen. You will immediately check if the water is safe for drinking and other uses. 
• The operation of the controller is surprisingly simple - just immerse the electrode in the water and the measurement result appears immediately on the reader.
•  Built-in physical function buttons for easy use of the device. 
• The HOLD function stores the measurement result and the SHIFT function changes the TDS/EC measurement mode 
• A practical case is included - protects the device from damage.
