Portable Meter Dissolved Oxygen – HORIBA LAQUA PD210-K
The Portable meter Dissolved Oxygen LAQUA PD210-K by HORIBA is your all-in-one solution for accurate field measurements of dissolved oxygen, pH, ORP, and temperature. Designed for reliability and precision, this rugged dual-channel meter delivers lab-quality results wherever you need them.
Dissolved Oxygen (DO) Measurement: Accurately measure DO concentration in ppm (mg/L) and % saturation, with 0.01 mg/L or 0.1% resolution.
Comprehensive Compensation: Automatically compensates for salinity, temperature, and atmospheric pressure to ensure precise DO readings.
Flexible DO Calibration: Supports up to 2-point calibration for optimal accuracy.
Advanced pH Calibration: Choose between 5-point calibration (NIST/USA buffers) or 6-point calibration (DIN buffers) with automatic adjustment.
Temperature Control: Features both automatic/manual temperature compensation and calibration.
ORP Capability: Optional ORP electrode calibration available (ORP electrode sold separately).
Smart Display: View offset, average slope, and real-time measurements on a bright monochrome LCD (50 x 50 mm) with a white LED backlight.
User-Friendly Functions: Auto log up to 500 data points, programmable auto shut-off (up to 30 minutes), auto hold, and calibration alarms (up to 90 days).
Durable Design: IP67 waterproof and dustproof rating, shock- and scratch-resistant with a non-slip grip—ideal for tough field environments.
Convenient Connectivity: Includes a phono jack for easy software upgrades via computer.
Battery Powered: Operates on 2 x AA batteries for maximum portability.
Complete Kit: Includes pH and DO electrodes with integrated temperature sensors, calibration solutions, electrode adapter, and a sturdy carrying case.
Warranty: 3-year warranty for peace of mind.
