Myron L Company 4PII 5948.004 Multi-Parameter Water Quality Meter

The Ultrameter II 4P is a waterproof and buoyant, water quality meter that analyses for conductivity, total dissolved solids (TDS), resistivity and temperature. Both Ultrameter II models deliver performance of +/-1% of reading (not merely full scale). This high level of accuracy has been achieved through advanced four-electrode conductivity cell technology, which eliminates polarisation 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.

The 4PII is equipped with fully automatic or user-adjustable temperature compensation (can be disabled), and a user-adjustable conductivity/TDS conversion ratio for greater accuracy when measuring solutions not in the microprocessor. The auto-shutoff maximizes battery life to more than 100 Hours or 5000 Tests. The non-volatile microprocessor provides datalogging (100 points) and data back-up (all calibrations & memory data are retained during battery change), and the built-in IR port allows for convenient data download with the uDock accessory (included). These instruments are easy to calibrate in the field.
