4HA7031L is a premium quality 1413 µS/cm conductivity standard that is prepared against a NIST traceable potassium chloride solution. Hanna conductivity solutions have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution. Hanna's line of conductivity standards have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened bottle.

2 meters of 1/4"OD-1/8"ID  tubing - Simdos^® 10

4.01 / 7.01 / 10.01 pH Value @25°C, (25 pieces X 20 mL Sachets). Each sealed sachet holds just the right amount of solution making every sachet as fresh as the day it was packaged! Perfect for use with testers and portable meters!
pH 4.01 buffer value is widely used in water purification plants, in the food industry, and wherever the pH is expected to be slightly acidic.

pH 7.01 is the most widely used among all buffer solutions. For this reason we have prepared it in a wider variety of sizes to meet your application needs.

pH 10.01 buffer solution is commonly used to calibrate equipment used for analyzing basic samples.

4HA700684P Cleaning Solution Sachets for Bread and Dough deposits contain cleaning solution specifically designed to eliminate impurities and residue deposits left by bread and dough samples. Clean electrodes ensure accurate calibration and measurements and can prolong the life of the electrode.

The 4HA70642L is a highly effective cleaning solution that is specially formulated for use with pH electrodes that become coated with cheese deposits. Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. Hanna's cleaning solutions eliminate impurities and residues that are left on the electrode surface after taking measurements of cheese.
