Horiba LAQUAtwin ORP Tester with 1 calibration point and temperature measurement (ORP-11)

LAQUAtwin ORP-11: The world's first pocket-sized ORP and Eh meter

Your mobile laboratory - for use on site: Ideal for water quality tests in swimming pools, environmental tests and many other applications.

HORIBA's unique compact meter integrates electrode, display and sample container to enable simple, effective on-site testing by direct measurement with a single drop. 

Versatile measurement: The only pocket-sized ORP meter that can measure not only the ORP value but also the Eh value (voltage measurement versus the standard hydrogen electrode or SHE)

Precision in every drop: The replaceable sensor with platinum disc enables measurements in samples as small as 0.3 ml (or 0.05 ml with sampling sheet).

Wide measuring range: With a measuring range from -1000 mV to 1000 mV, the meter ensures accurate readings over a wide range.

Simple automatic one-point calibration: The meter automatically recognises and calibrates the 225 mV standard solution included in the kit. The calibration can be adjusted with a different ORP standard solution.

Exceptional accuracy: With an accuracy of +/- 2 mV, the meter delivers precise results every time.

Auto Stable & Auto Hold measurement modes: To help users record stable readings, the meter displays a smiley face and can freeze the reading.

Temperature Compensation and Calibration: The meter displays temperatures up to 50.0 °C and allows for temperature compensation and correction through its calibration function.

IP67 rating: Water and dustproof meter with digital LCD display and backlighting

Complete package for ORP testing on the go: Each ORP-11 meter comes with a 225 mV ORP standard solution (14 ml), a cotton swab for polishing the platinum disc, a pipette, batteries and 5 sampling sheets.
