HM Digital (TDS-EZ) TDS Meter-Monitor for "Total Dissolved Solids"

Ideal for all basic water testing applications. The best value meter in the world! This meter reads the "Total Dissolved Solids" (TDS) in the water. TDS refers to any "salts" or charged ions in the water. It is not meant to check for specific items like "Lead" but rather get a general reading of ALL the ions in the water.  

• Economy model that is ideal for end-users.

• Hold Function: saves measurements for convenient reading and recording.
• Auto-off function: the meter shuts off automatically after 10 minutes of non-use to conserve batteries.
• Measurement Range: 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking 'x10' image.
• Display: large and easy-to-read LCD screen.
