METTLER TOLEDO US and Canada
Features Overview
– Plug and Measure functionality
– Integral high-performance
measuring circuit
– Robust digital output signal
– Calibration data stored internally
– System calibration in-line
UniCond conductivity / resistivity sensors for the METTLER TOLEDO Thornton M800
and M300 ISM provide exceptionally wide measurement ranges due to their
advanced built-in measuring circuit. The on-board measuring circuit eliminates
interference from leadwire resistance and capacitance. Only digital signals go back
to the transmitter. Advanced measuring techniques further contribute to superior
accuracy over the expanded range.
