HM Digital - Hand Held TDS Meter

HM Digital - Hand Held TDS Meter

TDS (total dissolved solids) meters are essential for monitoring the performance of your R.O. system.

According to HM Digital; Total Dissolved Solids are minerals, salts, metals etc. dissolved in a given volume of water. TDS is measured in mg per unit volume of water (mg/l) or parts per million (ppm).

HM's range of TDS test equipment starts with the HMTDSEZ, an economy model for basic water testing applications (0 - 9990 ppm). The meter is factory calibrated with 342ppm NaCl solution & it can be re-calibrated with a mini-screwdriver.

We have access to a wider range of TDS meters for more esoteric applications. Please call us on 01704 531556 for further details.
