Other Buffers Provided

Temperature dependence values of the solutions marked in bold are stored in the memories of 66 and 77 series meters. During calibration the value of the solution used, is automatically corrected according to the actual temperature.
Buffers of pH 3.56 4.01 6.87 7.41 9.18 are primary IEC (NBS) buffers, 1.68 is the primary IEC (NBS) standard for peripheral pH area, 10.01 is supplementary IEC (NBS) standard, 6.00 7.00 10.01 10.90 11.88 12.83 are standardized against IEC by a SEOJ 212 glass pH electrode.
Buffers are compatible with recognized international certified reference material for pH meters by the manufacturer Merck KgaA, 64271 Darmstadt, BRD, with furnished proof of certificates from the Institute for Technical Standardization, Metrology and State Testing. Values are at 25 0C. It is possible to provide each buffer individually.
