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.
