Myron L Ultrameter II

Simplifies and streamlines lab, industrial, remote field tasks with a ±1% performance reading.


The Ultrameter II simplifies and streamlines lab, industrial plant, and remote field location tasks. Just fill the cell cup, push a parameter key, and take the reading. Temperature compensation and range selection are both rapid and automatic. The Ultrameter II is a true one-hand operation instrument.

Ultrameter II 6PFCe models deliver a performance of ±1% of reading (not merely full scale). This high level of accuracy has been achieved through advanced four-electrode conductivity cell technology, a unique pH/ORP sensor, 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.*
