Use the HM Digital TDS Calibration Solution (342 PPM) to periodically re-calibrate your HM Digital TDS meter or HM Digital Water Quality Tester. This HM Digital TDS Calibration Solution is also known as Water Tester Solution and TDS Meter Calibration Solution. The C-342 is NaCl solution (342 PPM). The C-342 solution comes in lightweight bottle, sealed with a coated foam liner. The C-342 bottles are a convenient 3 oz. (88 ml) size. The Calibration Solution bottles have a convenient wide mouth, allowing a user to simply insert the meter into a stable bottle.

Instructions

  1. The calibration solution composition should match the conversion factor of the meter. HM Digital's TDS-3, for example, uses the NaCl conversion factor, so a NaCl calibration solution should be used
  2. HM Digital's COM-100 uses one of three selectable conversion factors (NaCl, 442 or KCl), so any of these three types of calibration solutions can be used for the COM-100
  3. Note - Some brands do not print the calibration solution composition on the label. Though NaCl is the most common, it is always recommended to contact the calibration solution manufacturer for verification
  4. Calibration Solution Values All of HM Digital meters can be calibrated to any point within the range of the meter. For example, the TDS-4 has a range of 0-9990 ppm. Therefore, it can be calibrated to any point within that range
  5. For best results, a meter should be calibrated as close as possible to what will be tested. For example, if the water you are testing is always around 150 ppm, then the meter should be calibrated as close to 150 ppm as possible
  6. All HM Digital meters are factory calibrated. Typically, with proper care and normal usage, HM Digital TDS and EC meters will retain their calibration for at least a year. Only calibrate a meter if you are sure you need to
  7. HM Digital calibration solutions have a shelf life of approximately 1 year unopened. Once opened, HM Digital calibration solutions have a shelf life of approximately 6 months, if properly stored and not contaminated. Store in a cool, dry place
  8. Contamination can occur if dipping a meter in water or a second calibration solution with a different value, and then dipping that meter back into the first calibration solution
