## Overview

The Oakton AO-00653-23 is a 500 mL conductivity and TDS calibration standard with a precise 23 µS/cm value, designed for professional lab and field use. Manufactured under ISO 9000 guidelines and traceable to NIST standards, it features printed conversion and temperature correction data for quick, reliable calibration of conductivity instruments.

## 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 degree 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 conductivity options range from 1 µs/cm to 200, 000 µs/cm ideal for laboratory and field analysis all Oakton conductivity and TDS standards are traceable to NIST standard reference materials solutions help you calibrate conductivity instruments to ensure accuracy standard values given at 25 degree C use when readings are expected to be around 23 µs/cm.

Review: EC/TDS - I use this solution to calibrate my ec/TDS meter. You put a bit in a container and calibrate. Easy to use. Product arrived fast and without damage.
Review: Apology and correction - I was expecting data sheet however the data that I thought was missing was printed on the back of the label. Happy with the product which was delivered same day as promised. Will buy again
