LAQUAtwin ORP-11: The World’s First Pocket-Sized ORP and Eh Meter

  • Versatile Measurement. The only pocket-sized ORP meter that can measure not only ORP value, but also Eh value (voltage reading vs. the Standard Hydrogen Electrode or SHE)
  • Precision in Every Drop. The replaceable sensor, featuring a platinum disk, enables measurements in samples as little as 0.3 ml (or 0.05 ml with sampling sheet).
  • Wide Measurement Range. Covering -1000 mV to 1000 mV, the meter ensures accurate readings across a broad spectrum.
  • Easy One-Point Auto Calibration. The meter automatically recognizes and calibrates the 225 mV standard solution included in the kit. Customize calibration using other ORP standard solution.
  • Exceptional accuracy. With an accuracy of +/- 2mV, the meter delivers precise results every time.
  • Auto Stable & Auto Hold Measurement Modes. Assisting users record stable readings, the meter displays smiley indicator and can freeze the reading.
  • Temperature Compensation and Calibration. Displaying temperatures up to 50.0°C, the meter allows for temperature compensation as well as correction through its calibration function.
  • IP67 Rating. Waterproof and dustproof meter with digital LCD and backlit display
  • Complete Package for On-the-Go ORP Testing. Each ORP-11 meter comes with a 225 mV ORP standard solution (14 ml), an abrasive cotton swab for platinum disk polishing, dropper, batteries, and 5 sampling sheets.
