Calibration Buffer Solutions-Hanna Instruments
Maximum accuracy is high on the agenda here at Hanna. Browse our Conductivity Calibration Solutions specifically produced for Conductivity meters and electrodes. Hanna conductivity electrodes can be calibrated in just a few minutes, wherever you are working, thanks to our range of conductivity solutions in different forms and values. Sachets, for instance, could be very useful out in the field as well as the laboratory.

Each label shows the product batch number, expiry date, and a conductivity/temperature correlation table. EC value is calculated at 25C. HI770710P is a set of premium quality pH 7.01 and 10.01 calibration buffers produced in accordance with ISO 3696/BS3978 standards using high purity salts, deionized water, certified weight-checked balances, and Class A glassware in a temperature controlled environment monitored with certified thermometers. Reported values are accurate to +/- 0.01 pH @ 25°C and are traceable to NIST Standard Reference Materials (SRMs).

Convenience of individual packaging
• Ideal for users that do not calibrate frequently
• Ideal for field use due to portability
• Every sachet is as fresh as the day it was packaged
• Light block packaging prevents oxidation from UV light that could alter the buffer value

Each sachet marked with lot number and expiration date.
• Hanna buffers are specially formulated to have an expiration of 5 years from manufacture for an unopened sachet.

Light block packaging
• Prevents any oxidation from UV light that could alter the buffer value.

Color coded label for easy pH buffer value identification.
• Easy to identify different buffer values
• Solution does not contain any dyes that may stain the reference cell of a pH electrode
