Description
Product Overview
The Myron L 4PII Conductivity Meter is engineered to deliver precise measurements of conductivity, resistivity, total dissolved solids (TDS), and temperature across a broad range of applications. Featuring an intuitive auto‑ranging system, the instrument automatically selects the optimal measurement range, eliminating the need for manual adjustments and reducing user error. Adjustable temperature compensation allows users to fine‑tune the meter for specific sample temperatures, ensuring that readings remain accurate regardless of environmental fluctuations. The device also includes a customizable conductivity/TDS ratio, giving professionals the flexibility to match industry‑specific standards and reporting formats. Constructed from a rugged polymer housing, the meter measures 8 × 3 × 3 inches and weighs just one pound, making it portable enough for field work while maintaining the durability required for demanding industrial environments. A built‑in date and time stamp records each measurement, facilitating traceability and compliance with quality‑assurance protocols. The 4PII model, first released in 2010, continues to be a trusted solution for laboratories, water treatment facilities, and environmental monitoring teams worldwide.
