Ph Buffers - Sartorius PT-15 Mode D'emploi

pH Buffers

The temperature coefficient of pH calibration buffers 4.00, 7.00, 10.00 and 4.01, 6.86,
9.18 are stored inside the instrument.
The buffers used to calibrate the instrument must exhibit the same temperature
characteristics as the stored values.
