Overview
The Horiba LAQUA 6010 is a rugged, handheld electrochemical analyzer engineered for field-deployable and routine laboratory measurement of pH, oxidation-reduction potential (ORP), and temperature in aqueous solutions. Based on potentiometric principle using a glass pH electrode and reference junction system, the instrument delivers traceable, stable readings compliant with standard electrochemical measurement protocols defined in ASTM D1293, ISO 10523, and USP . Designed for operational continuity in variable environmental conditions, the LAQUA 6010 integrates a microprocessor-controlled analog-to-digital conversion circuit with automatic endpoint detection and real-time drift compensation—ensuring high reproducibility across repeated measurements without recalibration between samples.
Key Features
- IP67-rated housing for dust and immersion resistance (up to 1 m for 30 min), enabling reliable use in outdoor monitoring, aquaculture ponds, food processing lines, and wastewater treatment sites.
- Intelligent electrode diagnostics: displays electrode slope (%), offset (mV), and response time—quantitative indicators aligned with U.S. EPA Method 150.1 requirements for sensor performance verification.
- Dual-mode temperature compensation: fully automatic (ATC) via integrated 10 kΩ thermistor probe or manual input (MTC) within –10.0 to 120.0 °C range.
- Two-point calibration with programmable buffer recognition (NIST-traceable options: pH 4.01/7.00/10.01 or DIN 4.00/6.86/9.18), supporting both single-slope and asymmetric calibration algorithms.
- Low-power architecture with auto-off after 10 minutes of inactivity; battery status indicator and audible alert at <15% remaining capacity.
- Tactile feedback via audible beep on keypress, enhancing usability with gloves or in noisy industrial environments.
- Non-volatile memory retains calibration coefficients, date/time stamp, and last-measured values—even after battery replacement.
Sample Compatibility & Compliance
The LAQUA 6010 is validated for direct immersion in liquid samples including freshwater, seawater, fermentation broths, pharmaceutical buffers, crude oil emulsions (aqueous phase), and beverage formulations. It supports measurement in non-aqueous or low-ionic-strength media when used with appropriate refillable double-junction electrodes (e.g., Horiba 9615S-10D). The device conforms to CE marking requirements under Directive 2014/30/EU (EMC) and 2011/65/EU (RoHS), and meets IEC 61010-1 safety standards for portable electrical equipment. Calibration traceability aligns with ISO/IEC 17025-accredited laboratories when paired with certified reference materials.
Software & Data Management
While the LAQUA 6010 operates as a standalone instrument, its RS-232 serial interface (via optional adapter cable) enables connection to PC-based data logging software such as Horiba’s LAQUA Connect. This facilitates export of timestamped datasets (pH, ORP, temperature, electrode diagnostics) in CSV format for audit-ready documentation. All calibration events—including date, buffer IDs, slope, offset, and temperature—are stored internally with GLP-compliant metadata. The instrument supports FDA 21 CFR Part 11–compatible workflows when deployed with validated software configurations and user access controls.
Applications
- Environmental monitoring: surface water, groundwater, and effluent pH/ORP profiling per EPA NPDES permit requirements.
- Aquaculture and hydroponics: real-time pond and nutrient solution management to maintain optimal biological activity.
- Food & beverage QA/QC: batch verification of acidified products, dairy pasteurization efficacy, and juice stability testing.
- Pharmaceutical manufacturing: in-process control of buffer preparation, cleaning validation rinse water, and bioreactor harvest pH screening.
- Petrochemical field analysis: corrosion potential assessment of cooling water systems and desalination feed streams.
FAQ
Does the LAQUA 6010 support automatic buffer recognition during calibration?
Yes—it identifies standard pH buffers (4.01, 7.00, 10.01 or 4.00, 6.86, 9.18) automatically when immersed, reducing operator error and improving calibration consistency.
Can the instrument store multiple calibration sets?
No—the LAQUA 6010 retains only the most recent two-point calibration; however, all parameters (slope, offset, date/time) are logged in non-volatile memory for review.
Is the temperature probe interchangeable or built-in?
It uses an integrated 10 kΩ NTC thermistor embedded in the electrode holder; external probes are not supported.
What is the recommended maintenance interval for the pH electrode?
Electrode performance should be verified before each use via slope/offset check; full reconditioning or replacement is advised when slope falls below 90% or offset exceeds ±30 mV at pH 7.00.
Does the device meet GLP/GMP documentation requirements?
Yes—when used with Horiba’s validated software suite and controlled calibration procedures, it satisfies core data integrity expectations for regulated environments under ALCOA+ principles.
