2-ElectrodeResistivity
Transmitter

Model Q45C2
ATI’s 2-Electrode Resistivity Transmitter provides the reliable and accurate low-level
measurements required for such high-purity water systems. Monitors provide large,
easy-to-read LCD displays with a second display line for indication of temperature or
other operational information. For those applications where results in resistivity units
are preferred, Q45C2 monitors can be programmed to display readings in Meg-ohm
units instead of microSiemens.
The monitor employs 2-Electrode conductivity sensors with low cell constants
to provide continuous measurements from 0-20 to 0-2,000 microSiemens. The
2-Electrode sensors are specifically designed for use in ultra-pure water and
nonfouling applications. The sensors are available in several mounting configurations
including 316SS compression fittings or sanitary-style. These sensors may also be
mounted submersion-style or in a hot-tap configuration.
