Hanna HI8410 Dissolved Oxygen Controller with Extended Range

Description

Advanced Industrial Dissolved Oxygen Measurement System

The Hanna HI8410 Dissolved Oxygen Controller is an advanced, panel‑mounted industrial instrument designed for continuous monitoring and control of dissolved oxygen (DO) in a wide range of process environments. Engineered with precision, it enables reliable detection of oxygen levels from 0.0 to 50.0 mg/L or 0 to 600% O₂ saturation, accommodating diverse operational needs in sectors such as aquaculture, wastewater treatment, fermentation processes, beverage manufacturing, environmental water monitoring, and chemical production. Its fundamental structure incorporates a galvanic DO probe interface — specifically compatible with the HI76410/4 or HI76410/10 — which delivers long‑term stability with reduced maintenance requirements compared to polarographic sensors. Designed for installation in a DIN‑standard panel mount, the HI8410 features user‑friendly membrane keypad controls, a large backlit LCD, and a transparent splash‑proof cover, ensuring visual clarity and durability in industrial working conditions. With its robust build and easy‑access functionality, it stands as a premium choice for operators seeking accurate dissolved oxygen measurement and tight process control.

Fail Safe Alarm System Functionality

An outstanding hallmark of the HI8410 is its Fail Safe Alarm System, which safeguards both the equipment and the controlled process against operational failures. This feature actively detects abnormal conditions such as power supply interruptions or signal loss, which can otherwise compromise production quality or environmental compliance. When triggered, a red LED alarm indicator on the front panel immediately notifies the operator of a fault, enabling rapid response and corrective measures. The alarm relay is configurable between 0.5 to 5.0 mg/L oxygen limits, allowing precise threshold definitions for diverse applications. For example, in aquaculture, maintaining proper oxygen levels prevents fish stress and mortality; in fermentation, oxygen management ensures product consistency; in wastewater treatment, it sustains microbial activity for pollutant breakdown. By integrating this fail‑safe mechanism, the HI8410 reinforces operational confidence, meeting stringent industrial safety standards while minimizing downtime.

Automatic and Salinity Compensation Capabilities

The HI8410 excels in measurement accuracy thanks to automatic temperature compensation (ATC) and salinity compensation functions. Dissolved oxygen solubility and membrane permeability vary with water temperature; ATC actively adjusts readings from -5°C to 50°C, ensuring precise output across seasonal and process temperature fluctuations. Salinity adjustments — within the 0 to 51 g/L range — enable accurate measurements even in saline or brackish water environments, making the device ideal for coastal aquaculture, seawater-based cooling systems, and certain industrial chemical processes. These compensation capabilities are supported by a built‑in thermistor in the compatible galvanic probe, feeding real‑time data to the controller. Such integrated adaptability allows the HI8410 to provide dependable analysis for operators working in challenging conditions, from freshwater to seawater scenarios, without manual recalculation or auxiliary instrumentation. In practical terms, this means a laboratory‑grade accuracy standard applied in continuous plant operation.

Integrated Calibration and Diagnostic Features

Calibration of the HI8410 is a straightforward single‑point process in saturated air, enabling quick setup with minimal downtime while maintaining high accuracy. The embedded diagnostic test functions, operable via the front panel keys, help isolate possible malfunctions through targeted checks of sensor output, alarm status, and analog signal integrity. The controller supports manual hysteresis adjustment between 0.5 and 2.4 mg/L, effectively reducing signal oscillations and preventing relay chatter during borderline readings. This attention to functional diagnostics makes it considerably easier for plant technicians to troubleshoot without disassembling the unit. The combination of calibration simplicity and diagnostic depth ensures that HI8410 delivers consistent, reliable measurements, meeting process control requirements even in heavily industrialized settings. This makes it a preferred choice in facilities where instrument uptime directly correlates with production throughput.

Analog Output and Process Recording Options

Data traceability is critical in regulated environments — the HI8410 meets this requirement with 0 to 20 mA or isolated 4 to 20 mA analog outputs, allowing effortless integration into SCADA systems, chart recorders, or digital data loggers. The analog output enables real‑time DO trend recording, supporting process optimization, quality assurance, and compliance documentation. By simply connecting a recording device to the dedicated contacts on the front panel, operators can archive live measurements without interrupting controller operation. This is a significant advantage in sectors like food and beverage production, where DO levels influence product flavor stability, and in wastewater management, where environmental discharge permits may require continuous proof of oxygen levels. Through its recording capability, HI8410 bridges operational measurement with strategic data management.

Practical Applications Across Industrial Environments

The versatility of the HI8410 makes it applicable to numerous industries where dissolved oxygen management is vital. In aquaculture, the controller maintains oxygenated water to support fish health and growth rates. In municipal wastewater treatment, it ensures aerobic bacteria efficiency, essential for breaking down organic pollutants. In fermentation and brewing, it regulates oxygen to prevent undesired aerobic reactions. In cooling water systems, proper oxygen control reduces corrosion risks. Additional applications include environmental water studies, chemical manufacturing processes, and marine research facilities. The controller’s combination of precision, flexibility, and alarm safety translates into real operational benefits such as reduced product loss, extended equipment life, and enhanced compliance with environmental regulations. For all these sectors, sourcing original units is crucial — tpt24.com, the world’s leading online store for HI8410, guarantees authenticity, premium build quality, and reliable delivery to any country, making it the trusted procurement partner globally.

Design, Build Quality, and User Interface

Constructed with a flame retardant ABS enclosure and a transparent splash‑proof front cover, the HI8410 is engineered to withstand harsh plant conditions including high humidity (up to 95% non‑condensing) and temperature extremes (-10°C to +50°C). Its DIN panel‑mount installation is supported by supplied brackets, ensuring secure fitment in control panels. The membrane keypad is both tactile and durable, providing direct access to key functions such as measurement mode, alarm setting, salinity control, calibration, and diagnostic tests. The large, continuously backlit LCD enhances visibility in dimly lit environments, a feature highly valued in water treatment plants, industrial fermentation chambers, and offshore aquaculture stations. Together, these elements reflect Hanna’s commitment to producing top‑tier instrumentation that marries rugged design with intuitive operation, making the controller user‑friendly without compromising environmental resilience.

Electrical, Control, and Operational Specifications

Operating on 115 VAC ±10% (50/60 Hz) power, the HI8410 includes a dosing relay rated at 2A (240V maximum, resistive load) capable of 1,000,000 mechanical strokes, reflecting industrial endurance. The dosing control modes — OFF, AUTO, and ON — are selectable via a rear panel switch, allowing manual or automated process integration. The over‑dosing control is adjustable from 5 to 60 minutes, preventing oxygen surplus that could damage processes or waste resources. Analog current output is isolated for better interference resistance, while the enclosure dimensions — 141 x 69 mm — permit compact placement even in multi‑instrument racks. With a manageable weight of 1 kg, the unit is simple to mount and service. In all aspects, the HI8410 demonstrates the synergy of precise sensing, secure process control, and operator‑centric design, underscoring why it is a preferred solution in oxygen‑critical industrial systems worldwide.
