Hanna HI83099 Advanced Portable COD & Multi-Parameter Photometer

Overview

The Hanna HI83099 is an advanced portable photometer engineered for precise, field-deployable chemical oxygen demand (COD) and multi-parameter water quality analysis. It operates on the principle of colorimetric absorption spectroscopy using a stable tungsten-halogen light source and precision narrow-band interference filters—optimized at 420 nm, 525 nm, 575 nm, and 610 nm—to eliminate spectral overlap and maximize assay specificity. Unlike single-wavelength benchtop units, the HI83099 dynamically selects the optimal wavelength based on the selected parameter and range, ensuring compliance with standardized test methods including USEPA 410.4 and ISO 15705 for COD determination. Its integrated optical architecture—comprising silicon photodiode detection, temperature-compensated signal processing, and SMD-based microcontroller logic—delivers high reproducibility across ambient conditions (0–50 °C, 30–95% RH, non-condensing). Designed for environmental laboratories, municipal wastewater operators, and industrial process control teams, the HI83099 eliminates the need for multiple dedicated analyzers by consolidating 36 critical water quality parameters into one rugged, handheld platform.

Key Features

• Triple-range COD measurement capability: Low Range (0–150 mg/L), Medium Range (0–1500 mg/L), and High Range (0–15000 mg/L), all compliant with EPA 410.4 and ISO 15705 protocols
• Dichromatic LED-driven optical system with automatic wavelength selection—no manual filter changes required
• IP67-rated enclosure for dust and temporary water immersion resistance, validated for field use in harsh outdoor or plant-floor environments
• Onboard GLP-compliant data management: 200-stored results with date/time stamp, sample ID, operator ID, and method identifier
• USB interface supporting direct export to CSV-compatible software (e.g., Excel, LIMS) without proprietary drivers
• Integrated real-time clock, backlight-adjustable LCD, and programmable auto-shutdown (10-minute idle timeout)
• Flexible power options: long-life 9V alkaline battery or universal AC/DC adapter (230 VAC input, 12 VDC output)

Sample Compatibility & Compliance

The HI83099 supports standard 13 mm round glass or plastic cuvettes and is compatible with all Hanna-certified reagent kits—including HI93754A-25 (COD-LR), HI93754B-25 (COD-MR), and HI93754C-25 (COD-HR)—which employ the dichromate oxidation method under acidic reflux conditions. Sample matrices include raw influent, secondary effluent, industrial discharge, surface water, and treated potable sources. All 36 pre-programmed methods adhere to internationally recognized analytical standards: Nesslerization for ammonia (HI93700-01/HI93715-01), DPD for free/total chlorine (HI93701-01/HI93711-01), TPTZ for low-range iron (HI93746-01), and SPADNS for fluoride (HI93729-01). The instrument’s firmware is validated for traceability under ISO/IEC 17025-accredited laboratory workflows and supports 21 CFR Part 11–compatible audit trails when paired with Hanna’s HI780 Data Manager software.

Software & Data Management

Data integrity is maintained through built-in GLP functionality: every stored measurement includes a timestamp, user-defined sample ID, and method code. USB connectivity enables seamless transfer of datasets to Windows/macOS systems without third-party utilities. Exported files follow ASTM D5116-compliant formatting—each row contains parameter name, concentration, unit, method reference, and uncertainty estimate (±10% for COD-LR). Optional HI780 Data Manager software provides trend visualization, statistical summary (mean, SD, CV%), and report generation aligned with ISO 17025 documentation requirements. Calibration logs—including zero-point verification history and date-stamped recalibrations—are retained independently and exportable for internal audits or regulatory review.

Applications

The HI83099 serves as a primary analytical tool across regulated and non-regulated water monitoring domains. Municipal wastewater treatment plants deploy it for daily influent/effluent COD profiling and nutrient tracking (NH₃-N, NO₂⁻-N, PO₄³⁻). Industrial hygienists use it to verify pretreatment compliance for electroplating (Cr⁶⁺, Ni²⁺), food processing (Cl₂ residual, COD), and pharmaceutical manufacturing (TOC proxy via COD-HR). Field technicians rely on its portability for stormwater outfall screening, landfill leachate assessment, and agricultural runoff analysis. Educational institutions utilize its intuitive interface and broad parameter coverage for undergraduate environmental chemistry labs, satisfying curriculum requirements for AP Chemistry and ABET-accredited environmental engineering programs.

FAQ

Does the HI83099 perform digestion internally?
No. The HI83099 is a photometer only; sample digestion must be conducted externally using a certified heating block (e.g., HI839800) prior to measurement.
Can it store calibration curves for custom reagents?
No. Only factory-loaded, Hanna-validated curves are supported to ensure method compliance and regulatory defensibility.
Is the instrument suitable for saline or high-TDS water?
Yes—provided appropriate matrix-matched blanks are used and interferences (e.g., chloride in COD assays) are mitigated per EPA 410.4 guidelines.
What is the warranty and service support structure?
Hanna Instruments provides a 2-year limited warranty, with authorized service centers in >60 countries and NIST-traceable calibration certificate options upon request.
How is traceability maintained for ISO 17025 accreditation?
Through GLP logging, external calibration with NIST-traceable standards (e.g., SRM 2028 for COD), and documented metrological validation per ISO/IEC 17025 Clause 6.4.
