NS pH仪解决方案

pH meters play an important role in industrial process controls. Chemical facilities, biological research companies and civilian water treatment plants need accurate and reliable pH meters to monitor and improve water quality and safety. Nationals small packaging and reliable, efficient power management meet the requirement portable pH units have for operating over long periods of time without changing batteries. These products also can withstand wide temperature ranges, allowing the meters to be used in any environment.
Component Highlights

*Op Amps - extremely low input bias current under 2 picoamps.

*Microcontroller - RISC core with on-chip SRAM and Flash memory provides high computing bandwidth, and additional integration gives high I/O bandwidth and system expandability.

*ADC - high-speed, high-resolution converters keep system power dissipation low.

*DAC - high-resolution, wide dynamic range converters interface easily with microprocessors
