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.

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.

The 4HA6221 Advanced pH/ORP Benchtop Meter is a streamlined benchtop meter with a large touch screen display, comprised of housing and an integrated pH / ORP measurement module. Compact and easy to operate, the benchtop meter is delivered with Hanna's 4HA1131B double junction combination pH electrode, together with 4HA7662-TW temperature probe.

Measure pH/MV (pH) or mV / Rel.mV (ORP) with temperature. Features 5-point pH Calibration capacity with automatic recognition for standard or custom buffers.
