EVAL-CN0359-EB1Z

EVAL-CN0359-EB1Z is an evaluation-board for CN0359 fully automatic high performance conductivity measurement system. Completely self-contained, microprocessor controlled, highly accurate conductivity measurement system ideal for measuring the ionic content of liquids, water quality analysis, industrial quality control and chemical analysis. Board comes preloaded with the code required to make the conductivity measurements. The circuit automatically detects either 100 ohm or 1000 ohm platinum (Pt) resistance temperature devices in 2-, 3-, or 4-wire configurations, allowing for added flexibility when measuring the temperature of the liquid. The circuit generates a precise AC excitation voltage with minimum DC offset to avoid a damaging polarization voltage on the conductivity electrodes. The amplitude and frequency of the AC excitation is user-programmable.

• User interface consists of an LCD display and an encoder push button
• Circuit can also communicate with a PC using a USB-to-UART bridge if desired
• Operates on a single 4V to 7V power supply
