COMPATIBILITY & APPLICATIONS

Designed for Water Quality Professionals

The Myron L 4PII Ultrameter II is engineered for professionals who demand accuracy in challenging environments. Since 1957, Myron L instruments have been trusted in reverse osmosis systems, deionization plants, cooling towers, boiler water testing, irrigation management, hydroponics, wastewater treatment, desalination facilities, and ultrapure water control for medical dialysis equipment. User-adjustable temperature compensation (up to 9.99%/°C) and customizable conductivity-to-TDS conversion ratios ensure precision across diverse water chemistries. Optional wireless download module enables seamless data transfer. Non-volatile memory retains all calibrations and stored samples even during battery replacement. Includes operation manual, pocket instruction card, certificate of compliance, and 9V battery.

💧 Factory calibration with NIST traceable solutions means the Myron L 4PII arrives ready for field use. For applications requiring documentation, request the optional certificate of traceability and NIST reference standards at time of purchase.
