Description
The Mettler Toledo FiveEasyPlus FP20 pH/mV meter is a reliable, user-friendly benchtop meter designed for pH and mV (redox) measurements in laboratory or educational environments. This unit comes with a glass electrode and the RS-P25 compact printer.
The FP20 offers a pH range of –2.00 to 16.00 with 0.01 resolution and ±0.01 accuracy, plus an mV range of ±2,000 mV with ±1 mV accuracy. Temperature measurement covers –5 to +105 °C with automatic or manual compensation. It features an intuitive interface with a clear LCD display and simple menu-driven operation.
Built-in RS-232 and USB ports allow easy connection to a printer or PC. The RS-P25 printer uses standard 57.5 mm paper rolls and prints GLP-compliant records at 2.3 lines per second. This combination offers a dependable solution for routine laboratory measurements and documentation.
