Pocket ORP and Eh Meter, 0.3 mL Sample Testing with Backlit LCD

Description

LAQUAtwin ORP-11 Pocket Water Quality Meter is designed for direct ORP and Eh testing from very small sample volumes, making it a practical choice for portable water quality measurement and routine laboratory use. HORIBA’s compact design integrates the electrode, display, and sample container into one handheld unit, allowing simple on-site testing from a single drop. With a minimum sample volume of 0.3 mL, or 0.05 mL when used with Sampling Sheet B, this meter helps reduce sample waste while supporting efficient day-to-day measurement.

This model measures both ORP and Eh, giving users added flexibility for oxidation-reduction potential testing. The platinum disk replaceable sensor supports direct measurement, while the wide ORP range of -1000 to 1000 mV with 1 mV resolution and ±2 mV accuracy supports dependable performance across a broad range of applications. One-point calibration with automatic standard recognition simplifies setup, and additional functions such as temperature compensation, temperature calibration, auto hold, auto stable mode, low battery indication, and automatic power off support user-friendly operation. With IP67 water and dustproof protection, backlit LCD display, and included accessories for portable use, LAQUAtwin ORP-11 is well suited for convenient small-volume ORP and Eh testing.
