HORIBA PC110 & PD110 Portable Multi-Parameter Water Quality Analyzers

Overview

The HORIBA PC110 and PD110 are rugged, dual-channel portable water quality analyzers engineered for field-deployable precision in environmental monitoring, wastewater management, aquaculture, drinking water verification, and educational laboratory applications. Designed around electrochemical measurement principles—potentiometric for pH/ORP, conductometric for EC/TDS/resistivity/salinity (PC110), and galvanic (Clark-type) amperometric for dissolved oxygen (PD110)—these instruments deliver traceable, repeatable results under demanding real-world conditions. Each unit features a fully sealed IP67-rated housing capable of withstanding submersion at 1 m depth for 30 minutes, mechanical shock resistance validated per automotive-grade polycarbonate construction, and chemical resilience against ethanol, weak acids/bases, and hydrocarbon exposure—enabling rapid decontamination without compromising sensor integrity or housing longevity.

Key Features

• Ruggedized IP67 enclosure with polycarbonate housing—2× higher impact resistance than conventional ABS, certified to IEC 60529 standards.
• Ergonomic handheld form factor with integrated electrode hooks supporting simultaneous attachment of two sensors; optional rotating benchtop electrode stand enables stable single-handed operation.
• Extended battery life: >200 hours (PC110), >500 hours (PD110) on two AAA/LR03 alkaline or Ni-MH rechargeable cells; power consumption reduced by ~10% versus prior-generation portable meters.
• High-contrast 64 mm × 52 mm backlit LCD with diagnostic icons, stability indicators, slope monitoring (acidic/alkaline calibration curves), and real-time electrode status feedback.
• Intelligent measurement modes: Auto-Hold (freezes display upon signal stabilization) and Auto-Stable (continuous refresh with visual stability flag).
• Comprehensive data governance: 1000-point internal memory with date/time stamping, GLP/GMP-compliant audit trail, RS232C serial interface for direct PC transfer, and optional thermal printer support meeting FDA 21 CFR Part 11 requirements for electronic records.

Sample Compatibility & Compliance

The PC110 and PD110 are optimized for aqueous samples across natural waters (rivers, lakes, estuaries), treated effluents, potable supplies, industrial process streams, and marine environments. Both models accept industry-standard BNC and DIN-style electrodes—including HORIBA’s 93004-07 pH electrode (titanium/platinum-black reference system) and 93004-25 conductivity cell (k = 1.0 cm⁻¹). The PD110 integrates a factory-calibrated galvanic DO probe compliant with ISO 5814:2012 and ASTM D888–22 for dissolved oxygen determination. All calibration protocols support USA, NIST, and user-defined buffer sets; salinity and atmospheric pressure compensation algorithms align with ISO 7888 and EN 27888 standards. Device firmware and data handling workflows are designed to support ISO/IEC 17025-accredited laboratories and EPA Method-compliant field operations.

Software & Data Management

Data acquisition adheres to Good Laboratory Practice (GLP) and Good Manufacturing Practice (GMP) frameworks. Each stored measurement includes parameter values, temperature, electrode ID (if encoded), calibration history, operator ID (via optional input), and timestamp synchronized via built-in real-time clock. RS232C output enables direct integration with LIMS platforms or custom data aggregation software. Exported files follow ASCII-delimited format compatible with Excel, MATLAB, and statistical analysis tools. Calibration due-date alerts (configurable from 1–400 days), slope deviation warnings, and electrode impedance diagnostics ensure ongoing measurement validity. Firmware updates are delivered via HORIBA’s secure technical portal and maintain backward compatibility with legacy calibration certificates and audit logs.

Applications

• Regulatory compliance monitoring: EPA 150.1 (conductivity), EPA 150.2 (pH), ISO 10523 (pH in water), ISO 7888 (electrical conductivity), and ASTM D1293 (pH of water).
• Field-based environmental assessment: Stream health evaluation, wetland restoration tracking, stormwater runoff characterization, and coastal salinity profiling.
• Process control in water treatment: Coagulation/flocculation optimization, disinfection residual correlation (pH/ORP), membrane system feedwater monitoring (TDS/resistivity).
• Aquaculture and hydroponics: Real-time DO/pH/EC management to maintain optimal growth parameters for finfish, shellfish, and controlled-environment agriculture.
• Academic instruction: Undergraduate and graduate-level environmental science labs requiring robust, intuitive instrumentation with full metrological traceability.

FAQ

What calibration standards are supported?
The PC110 and PD110 support USA, NIST, and custom calibration buffers. Optional NIST-traceable standard solutions (pH 4.01, 7.00; conductivity 1413 µS/cm, 12.88 mS/cm) are available upon request.
Can the instruments operate submerged?
Yes—both models meet IP67 ingress protection: they remain fully functional after immersion in freshwater at 1 m depth for 30 minutes.
Is dissolved oxygen measurement temperature-compensated?
Yes—the PD110 applies automatic temperature compensation per ISO 5814:2012 using an integrated thermistor; barometric pressure compensation is also enabled to correct for altitude effects.
How is data security ensured during transfer?
RS232C communication supports hardware handshaking and configurable parity/error-checking protocols. When paired with HORIBA-certified thermal printers, output meets FDA 21 CFR Part 11 requirements for signed, time-stamped hardcopy records.
Are replacement electrodes and accessories available globally?
All consumables—including pH, conductivity, and DO sensors, calibration kits, carrying cases, and electrode stands—are distributed through HORIBA’s authorized global service network with documented shelf-life and lot-specific certification.
