Myron L Water Quality Test Calibrations and Buffer Solutions Hanna Instruments Water Quality Tester Calibration and Buffer Solutions

Conductivity Standard Solutions and pH Buffers are used for factory calibration of water quality testers. Regular use of these solutions is recommended to ensure specified instrument accuracy. Frequency of conductivity recalibration depends upon use, but once every month should be sufficient for an instrument used daily. pH models, depending upon use, should be recalibrated with pH 7 Buffer every 1-2 weeks, and checked with pH 4 and/or 10 Buffers at similar intervals.

Benefits of Calibration and Buffer Solutions

  • Easy to Use
  • Calibrating Water Treatment Instruments Regularly Ensures the Accurate Test Results
  • Myron L solutions are NIST Traceable 
  • Myron L Company Standard Solutions have an accuracy of ±1% based on values published in the International Critical Tables
  • pH Buffer Solutions 4, 7 and 10 are mold inhibited and accurate to within + 0.01 pH units @ 25°C

TDS Calibration Solutions by Myron L

442 Natural Water™ Standard Solution is NIST Traceable and is used in calibrating many test instruments. It is the best choice when measuring boiler and cooling water samples, city water supply, lakes, wells, etc. "442" refers to the combination of salts mixed with deionized water to comprise this standard: 40% sodium sulfate, 40% sodium bicarbonate, 20% sodium chloride. A combination of standard salts is necessary since natural water salt type and concentration can vary greatly by location.

ORP Standard Test Solutions by Hanna

ORP standard solutions allow you to test the precision of ORP electrodes. For example, by immersing the electrode in HI 7020 solution, you should read within the 200 to 275 mV range (@20°C/68°F). If the reading is outside the indicated interval, clean and condition your ORP electrode in HANNA® pretreatment solution.
