HM Digital C342 TDS and EC Calibration Solution 90ml (3 fl oz) | Lab-Grade NaCl Solution for Accurate Meter Calibration

• NaCl calibration solution, available in 342 ppm or 1000 ppm
• Comes in lightweight HDPE plastic bottles
• Sealed with a coated foam liner
• 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 andTDS Meter Calibration Solution
• The C-342 is NaCl solution (342 PPM)

• Prepare the Meter — Ensure your HM Digital TDS or EC meter is clean. Rinse the probe with distilled or deionized water and gently pat dry with a lint-free cloth to remove any residue.
• Immerse in Solution — Pour a small amount of the HM Digital C342 calibration solution into a clean container or directly into the meter's calibration cup. Immerse the meter's probe into the solution, ensuring the sensor is fully submerged.
• Calibrate the Meter — Allow the meter to stabilize for a minute. Follow your specific HM Digital meter's calibration procedure, typically involving adjusting the reading on the meter until it displays the correct concentration (342 ppm) for the solution.
• Finalize and Store — Once calibrated, rinse the probe again with distilled water. Seal the C342 solution bottle tightly with its foam liner and store it upright in a cool, dry place away from direct sunlight to maintain its accuracy for future use.
