Oakton AO 00653 18 Conductivity Standard 1413 - Accurate Conductivity Measurement Solution for Precise Analysis Review

Exceptional results from day one. After I put it to the test, the readings were consistently reliable and accurate. The convenient packaging allows for easy access and storage, making it a hassle-free addition to my lab equipment.

Oakton 1413uS Standard ordered, arrived on 03/01/21 and the solution had an expiration date of 03/25/21, less than a month later. I had to ship it back to get a refund so I had to drive 10 miles to a UPS store to have it delivered and get a $20 refund. Needless to say I won't do it again.

These solutions that have been sent to me have a very short date as they expire in January 2022, they will not arrive supplied with a certificate of analysis or with traceable certificates of calibration as the reference material should I try to contact the supplier to ask for an explanation and it was difficult for me. You've reached the liquid level near the label, I doubt it's 500ml
