The Myron L UltraMeter II 4PII model delivers performance of 1% of reading (not merely full scale). This high level of accuracy has been achieved through advanced four-electrode conductivity cell technology and powerful microprocessor-based circuitry. With displayed values of up to 9999, the full four-digit LCD ensures resolution levels never before possible in such affordable instruments. Factory calibrated with NIST traceable solutions, each UltraMeter II may be supplied with both certification of traceability and NIST traceable solutions for definitive calibration.*

*NOTE: NIST certificates are optional and an extra charge. This product is also available with bluDock™ technology. See more model options below.
