Manumesure proposes a complete range of calibration solutions for measuring pH, redox potential and conductivity. With the aim of meeting your needs as closely as possible, the range comprises certified standard solutions which can be traced to the SI units system.
The PPD26 pH-meter/millivoltmeter is ideal for routine measurements and teaching purposes. This instrument is
extremely simple to use: just 4 rotary buttons control both calibration and
measurements.
