TDS Conductivity Standard Solutions 442 – 30 Myron L

TDS Conductivity Standard Solutions 442 – 30 Myron L

TDS Conductivity Standard Solutions 442 – 30 Myron L is a specially formulated calibration solution designed to ensure the accuracy and reliability of conductivity and Total Dissolved Solids (TDS) measurements. Manufactured by Myron L Company under strict quality control using reagent-grade salts and high-purity deionized water (resistivity ≥5 megohms-cm), this solution is traceable to NIST (National Institute of Standards and Technology) and conforms to values published in the International Critical Tables.

This 442 – 30 solution contains a blend of salts (40% sodium sulfate, 40% sodium bicarbonate, 20% sodium chloride) that simulates the ionic composition of natural fresh water. It is particularly suited for low-conductivity calibration requirements, making it ideal for laboratory, environmental, and water treatment applications. Available in a quart-sized (32 oz) bottle, it is ready to use and essential for maintaining the precision of Myron L handheld instruments and other conductivity meters.

features

1. accurate nist-traceable calibration
   Formulated to ±1% accuracy and traceable to NIST standards for trusted calibration.

2. low-conductivity standard
   With a conductivity of 30 µS/cm and TDS of 30 ppm (442 scale), it is ideal for simulating freshwater conditions.

3. natural water equivalent formulation
   Uses the 442 formula (40% Na₂SO₄, 40% NaHCO₃, 20% NaCl) for more realistic calibration results.

4. stable and consistent performance
   Ensures long shelf life and calibration reliability over time, with no mixing required.

5. convenient packaging
   Supplied in a user-friendly quart (32 oz) plastic bottle, ready for direct use.

6. compatible with various instruments
   Suitable for all Myron L meters and compatible with other conductivity and TDS measurement devices.
