Looking for a portable but precise conductivity measurement to fulfil USP 27 regulations on pure water?
For this purpose WTW, Weilheim, Germany, offers the Cond 340i, a precise hand held conductivity meter. It is a instrument including memory, datalogger and RS 232 interface with all features to perform conductivity measurements for every application. For USP measurements the temperature compensation can be switched off, a special routine enables the instrument to check the cell constant of the conductivity probe. But the meter only measures as well as the sensor. The combination of a precision instrument with a precision conductivity cell gives the maximum safety for your measurement!
WTW offers two types of USP-kits including LR 325/01 sensor, flow-thru vessel, 5 µS/cm standard solution and NIST-traceable resistors according USP 27 regulations.
