HANNA INSTRUMENT

If you take measurements in alkaline environments, now you can use buffer solutions at pH 9.18 in addition to the pH 10 buffer. This means better accuracy and versatility, especially with microprocessor pH meters, which can be calibrated at both pH 9.18 and pH 10.

pH 9.18 Buffer Solution

All pH 9.18 solutions show the batch number, the expiration date and have a pH/temperature correlation table on each bottle. HI 5091, HI 6091, HI 70009C, HI 7009L/C and HI 8009L/C are provided with a certificate of analysis. Traceability with NIST Reference Standard HANNA instruments buffer solutions are prepared using very pure chemicals, in closely controlled laboratories, and with pH meters calibrated with NIST references.
