## Overview

The Oakton Conductivity and TDS Standard 1413 S is a 500 mL lab-grade calibration solution with a precise conductivity value of 1.413 mS, certified under ISO 9000 and traceable to NIST standards. It features printed calibration and temperature correction data on the bottle for quick, accurate use, supports a wide conductivity range, and offers a sealed shelf life of 1 year to ensure consistent, reliable sensor calibration for professional and industrial applications.

## Description

KCl, NaCl and 442 conversions printed on the bottle for ease of use (excluded on 60-mL bottle, but included in insert). Temperature corrections are printed on the bottle, with certified values listed in tables and referenced to 25°C (excluded on 60-mL bottle, but included in insert). Manufactured under ISO 9000 quality guidelines and traceable to NIST standards. If unopened, shelf life is 1 year. If opened recommended shelf life is 4 months. Conductivity options range from 1 µS/cm to 200,000 µS/cm

Review: This is the real stuff. I had a problem with a bad mix of a 1000ppm "calibration standard" NaCl solution when trying to calibrate my EC meter for home hydroponics. Sent it back and bought this. Comes sealed. Has a temperature/EC grid on the label so with a thermometer on hand, it makes calibrating an EC meter dead on accurate. This is laboratory grade. I'll be sticking with this product for calibrations.
Review: I used this once to calibrate a water quality sensor we had deployed at a field site. The second time we used the solution, there were black globes of mold growing in it. The standard was wildly off when we attempted to use it (silly to try this) and the solution was within the use date (hadn't expired yet). We stored the solution according to the label and we handled the calibration solution using gloves and on a clean surface. I have used many conductivity solutions and have never had this issue. Maybe it was just a one off, but I will be using a different conductivity solution from here on out. We can't afford to use poor quality calibration solutions to calibrate thousand $$ instruments while in remote places
