Description
Portable pH / ORP / Ion / Temperature Meter – Jenco | Model 6250
The Jenco Model 6250 is a professional-grade portable pH/mV/Ion/Temperature meter designed for chemists and laboratory professionals requiring high-resolution ion and pH measurement in the field or laboratory. The 4.5-digit readout with programmable resolution to 0.001/0.1 pH and 1/0.1 mV provides analytical-level precision in a handheld format.
A defining feature of the 6250 is its direct ion concentration readout capability. After calibration with standard solutions, the meter displays ion concentration directly in the units of the calibration standards, eliminating manual calculation. This makes it particularly useful for ion-selective electrode work in water chemistry, environmental monitoring, food analysis, and industrial quality control.
The instrument features a splash-resistant watertight case with mechanical touch keys and audio feedback for reliable use in demanding environments. BNC connector for pH/mV/ion input and 8-pin DIN ATC connector ensure compatibility with a wide range of electrodes. RS-232C output enables IBM-compatible PC communication. High 50/60 Hz noise rejection protects measurement integrity in electrically noisy environments.
