Pressure/Level: The CS450 pressure transducer has a static accuracy of ±0.1% FS, 0-60°C. Options include a higher accuracy version (±0.05%) and a titanium body for harsh conditions. Radar Level: The CS475 is a low-maintenance level sensor that is ideal for areas where submerged sensors can be damaged. pH: The CS525 is a rugged ISFET pH probe which is suitable for nearly any liquid pH-monitoring application--from the lab to harsh field sites.
