HM Digital TDS Hand-held Tester TDS-EZ
Handheld TDS Tester by HM Digital TDS-EZ
This digital TDS pocket tester by HM Digital is used for measurement of Total Disolved Solids or TDS (mg/L) in water. The TDS reading of water in a cup collected from the RO faucet will allow you to monitor the RO membrane performance and the TDS of your tap water for comparison. If product water reads high TDS (compared to values of a new membrane), this means the RO membrane stopped working and it is time to change it.
It is a digital meter with an easy-to-read LCD screen.
Ideal for residential systems but can be used also for water produced by commercial systems. Accurate due to its advanced microprocessor technology.
Using the Hold Function, it saves measurements for convenient reading and recording.
Using the Auto-off Function, the tester shuts off automatically after 10 minutes of non-use to save batteries.
