Other features


In comparison with CO-505 the meter has smaller display without backlight. There is no possibility to "hold" the reading on the display and no information about the reading stabilisation. Meter does not create calibration reports. In CPO-502 there is no possibility of viewing the electrode's buffer and slope. CCO-502 has no function of automatic calculations of the α coefficient for natural and ultra pure water.


The standard CPO-502 set includes CT2B-121 temperature sensor with Pt-1000B resistor, EPS-1 pH electrode for measurements in clean water. It should not be used in other types of liquids. Measurements in liquids with sediments should be made with use of IJ-44A pH electrode, which enables measurements in various samples of both pure and contaminated liquids and semi-solids. Its unusual construction („intermediate junction”) protects the real junction (diaphragma) of the electrode against clogging, ensures stable measurements in these types of liquids or semi-liquid mass, in which other electrodes stop working quickly. When properly handled, the electrode's lifetime is longer than the standard electrodes.
