TDS / Conductifity Standard Solution 442-300 Myron L

TDS / Conductifity Standard Solution 442-300 Myron L

The TDS / Conductifity Standard Solution 442-300 Myron L is a high-precision calibration solution designed for accurate and reliable calibration of conductivity and TDS (Total Dissolved Solids) meters. Packaged in a 32 oz (quart-sized) bottle, this solution is prepared under stringent laboratory conditions using reagent-grade salts and high-purity deionized water with a resistivity of at least 5 megohms-cm.

The TDS / Conductifity Standard Solution 442-300 Myron L is part of Myron L’s proprietary 442 Natural Water Standard series, comprising 40% sodium sulfate, 40% sodium bicarbonate, and 20% sodium chloride—formulated to simulate the ionic content of natural fresh water sources. This makes it especially suitable for calibrating instruments measuring boiler water, cooling systems, municipal water supplies, wells, lakes, and similar applications.

Factory-calibrated and traceable to NIST (National Institute of Standards and Technology), the 442-300 solution ensures consistent and accurate readings with ±1% accuracy. Regular use of this standard solution is recommended to maintain instrument performance and compliance.
