Myron L 442-150 TDS Conductivity Standard Solution

Myron L 442-150 TDS Conductivity Standard Solution

The Myron L 442-150 TDS Conductivity Standard Solution (150 ppm, 32 oz) is a precision-formulated calibration solution designed to simulate natural water composition for accurate instrument calibration. It is ideal for use in applications involving water samples from boilers, cooling systems, city supplies, lakes, and wells. The “442” standard represents a proprietary salt mixture—40% sodium sulfate, 40% sodium bicarbonate, and 20% sodium chloride—crafted to mimic the conductivity characteristics of natural fresh water sources. This ensures reliable, repeatable results when calibrating conductivity and TDS meters.

features

1. natural water mimicry
   Based on the 442 blend, the solution closely replicates the ionic properties of natural fresh water, ensuring relevant calibration for environmental and industrial samples.

2. versatile application
   Suitable for calibrating instruments before analyzing a variety of water types including boiler water, cooling water, municipal water supplies, lakes, and wells.

3. high accuracy and reliability
   Delivers calibration accuracy of ±1%, maintaining confidence in the precision of TDS and conductivity measurements.

4. ready-to-use solution
   Comes pre-mixed and colorless in a convenient 32 oz (quart) bottle for easy application in lab or field environments.

5. NIST-traceable
   Manufactured under strict quality conditions, using reagent-grade salts and deionized water, and traceable to NIST standards for assurance in quality and performance.

6. broad instrument compatibility
   Designed for Myron L meters and compatible with most standard conductivity/TDS meters used across industry, environmental monitoring, and research.
