TDS Meter EZ [HM Digital]

Ideal for all basic water testing applications. The best value meter in the world!
Regularly test to make sure your Reverse Osmosis Equipment is producing pure drinking water; when the TDS starts to climb over 20 ppm, you know it's time to change the membrane.

Features:

Economy model that is ideal for consumers.
Highly efficient and accurate due to its advanced microprocessor technology.
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.
Factory Calibrated: our meters are calibrated with a 342 ppm NaCl solution. Meters can be recalibrated with a mini-screwdriver.
Fun, translucent blue housing that's very strong and durable.
Includes a TDS chart sticker on the back of the meter that explains TDS values. -see other picture
