📏 Calibrate like a pro — precision you can trust, results you can flaunt!
This 2-pack conductivity standard set offers precise 2-point calibration with NIST traceable potassium chloride solutions at 100 μS and 1413 μS. Designed for professionals demanding accuracy, it includes TDS cross-reference values, a free Certificate of Analysis, and temperature vs conductivity tables. Ideal for verifying meter linearity across typical working ranges, it ensures reliable, audit-ready measurements for water testing, hydroponics, and aquaculture. Each 250 mL bottle expires 1 year after manufacture, maintaining peak calibration integrity.

It is useful for quickly calibrations
It is useful for quickly calibrations. I used it to be sure if my new HANNA conductivity meter was well calibrated. It was very important to take the decision for to chance the membranes in a reverse osmosis in a water treatment plant. Excellent product. Good and cheap.

Good product, crummy plastic cap broke to easily
The cheap cap broke when I dropped the bottle about a foot onto a countertop. I had to purchase a plastic container to salvage the product period but otherwise it works fine or I would have given it five stars because it is what I expected and the value was okay for the price and to save me from going to a store.

Half expired, Biopharm considers reasonable.
Did not like buying an item that one of the bottles only had 6 months left from expiration, Stable or not, selling an item halfway through its shelf life is not cool, yet Biopharm felt it was okay, even after I talked with them.

Water with known ppm
For a million dollars. Does what it’s supposed to do, just have to sell my house to calibrate my meter.
