Portable pH/ORP meter LPRPM-A11

Overview

Portable pH/ORP meter LPRPM-A11 with high precision can improve temperature measurement accuracy through manual temperature calibration. It measure pH, mV, ORP, temperature of the sample. Equipped with built-in system menu helps in customize selection of up to 9 functional parameters. The unique calibration due reminder alerts user to calibrate the pH meter regularly. The Multi-mode power solution ensures smooth instrument usage. Its complied in accordance with GLP standards.

Features :

  • Measurement pH range: (-2.00) to 20.00 pH
  • pH accuracy: ± 0.002 pH up to three decimal points
  • Auto calibration recognition using 1 to 5 point calibration for pH mode
  • 1 point offset calibration for ORP mode allows to adjust the display value to a known standard
  • The mV measurements (relative & absolute) for accurate ORP readings
  • Automatic end point locking system for stable measurement (browsing & recording)
  • Automatic electrode slope display helps user decide whether to replace the sensor
  • Extended memory can store up to 500 sets of measurement data
  • Built-in clock automatically notes the date, time
  • USB communications interface sends data to PC
  • One touch reset automatically recovers the meter to factory default settings
