HI-83305-02 Multi-parameter Photometer & pH Meter for Boilers and Cooling Towers

The HI-83305-02 Multi-parameter Photometer & pH Meter, supplied by GAPS Water Treatment, is a state-of-the-art benchtop instrument individually designed for the unique challenges of boiler and cooling tower water management. Combining photometric and pH measurement capabilities in one compact unit, it streamlines essential testing while guaranteeing highly accurate, repeatable results for professional water quality programs.

Advanced Optical System – Precision You Can Trust

This meter features an advanced optical system that stands out among benchtop photometers. High-efficiency LEDs, narrow band interference filters, a focusing lens, and both silicon and reference detectors work together to minimize interference from environmental changes or cuvette imperfections. This unparalleled design ensures that your photometric readings remain precise, consistent, and reliable, every time.

Full-spectrum Analysis for Industrial Systems

Equipped with 30 programmed methods to measure 18 critical water quality parameters, the HI-83305-02 is tailored for the rigorous demands of both boiling and cooling tower systems. It covers vital measurements such as oxygen scavengers—which are key for removing residual dissolved oxygen and preventing corrosion of steam-generation equipment—and silica, a main factor in deposit formation that can reduce system efficiency. Monitoring these and other important factors like ammonia, iron, chromium, and phosphate is essential for preventing corrosion, scaling, and microbial fouling while ensuring your system operates at peak performance.

Dual Measurement Functionality

To optimize space and increase testing efficiency, the HI-83305-02 not only performs photometric analyses but also functions as a professional digital pH meter. Its digital pH/temperature electrode input allows quick and reliable pH measurement, with calibration data conveniently stored in the probe for easy hot swapping and accurate, temperature-compensated readings.

Absorbance Mode and Calibration

An absorbance measurement mode empowers users to validate system performance (using CAL Check standards) or develop their own concentration-versus-absorbance curves—a valuable tool for laboratories, advanced tech users, and educators interested in the Beer-Lambert Law.

Robust Features for Industrial Use

• Built-in Reaction Timer: Ensures accuracy for time-sensitive photometric procedures.
• Good Laboratory Practice (GLP): Tracks calibration logs, including date, time, buffers, offset, and slope—enabling traceability and compliance.
• Data Logging: Stores up to 1000 photometric and pH readings, all easily exportable via USB for fast record-keeping and analysis (.CSV format).
• Rechargeable Lithium-Polymer Battery: More than 500 photometric measurements or 50 hours of continuous pH measurement per charge, ideal for field and benchtop work.
• User-friendly Display and Controls: Intuitive navigation with a backlit 128 x 64 Pixel Graphic LCD display for easy use in any environment.
• Comprehensive Connectivity: Two USB ports for efficient data transfer and flexible powering options.

Designed for Real-world Boiler and Cooling Tower Applications

The HI-83305-02 is engineered for the day-to-day realities of water treatment. Its ability to precisely monitor oxygen scavengers significantly reduces the risks of corrosion, while accurate silica measurement protects against scaling—a major cause of maintenance downtime and lost efficiency. Additional critical tests—including for ammonia, chromium, iron, and phosphate—allow you to keep water chemistry balanced and extend the operational lifespan of expensive equipment.
