Conductivity Meters

CONDUCTIVITY/TDS/SALINITY/TEMPERATURE METER, hand held
Waterproof, portable conductivity meter with TDS, resistivity and three salinity
scales. This meter automatically recognises the probe type (two or four ring)
and allows the user to adjust the nominal cell constant.
Capable of performing all three stages USP <645> method required for EC mea-
surement of ultrapure water. Choose from seven memorised standards and
obtain up to a five-point conductivity calibration. For salinity (% range), C30­
5820 standard allows users to make a one-point calibration.
EC and TDS measurements are fully customisable and include: cell constant
selection, selection of linear or natural water (non-linear) or no temperature
compensation (for actual conductivity reading), configurable temperature com-
pensation coefficient range, choice of reference temperatures and a selectable
TDS factor. Features data logging transferrable to a PC with the supplied USB
cable and software.
