By providing both manual and automatic dosing modes, it supports routine operations, rapid troubleshooting, and preventive maintenance. Users can fine‑tune a programmable setpoint to activate the dosing relay above or below target pH, ensuring optimal chemical balance in varied solutions. Beyond technical excellence, it is a cost‑effective integration for modern process lines. As the global leader in authentic Hanna Instruments supply, tpt24.com guarantees delivery to any country with full warranty assurance and quality verification, making it the premier destination for acquiring genuine BL981411 mini controllers without compromise.

Rugged Design with Fire Retardant Protective Housing

Durability and protection are central to the BL981411 design philosophy. The casing is constructed from fire‑retardant material, shielding internal circuitry from both environmental and operational hazards. The unit’s mechanical integrity is enhanced by precision‑machined installation brackets, allowing easy sliding insertion into control panels for stable, vibration‑free mounting. Fitted with a large, clear LCD display, the controller provides immediate at‑a‑glance readings of pH values, dosing status, and alarm conditions. All critical control points—such as calibration and setpoint adjustments—are accessible through front‑panel trimmers, push‑buttons, and a three‑position dosing mode selector (OFF, Auto, ON). LED indicators further support status monitoring: green for measurement mode, orange/yellow for active dosing, and blinking red for overtime or alarm events. By integrating intuitive ergonomics with rugged mechanical design, Hanna ensures that the BL981411 withstands the rigors of industrial demands while retaining simplicity for everyday operation.

Adaptive Dosing Relay with Overdose Protection Features

The dosing relay in the BL981411 is engineered for precision actuation and overload safety. Configurable for acid or alkaline dosing, it responds intelligently to measured deviations from the user‑defined setpoint. In acid mode, the relay activates when pH exceeds the setpoint; in alkaline mode, activation occurs when pH drops below it. The relay’s capacity supports a maximum load of 2A, with built‑in fuse protection to prevent damage from connected pumps or valves. For enhanced safety, a selectable overdose protection system can halt dosing when activation continues beyond a preset window adjustable between 5 and 30 minutes. This prevents chemical imbalances and equipment wear arising from continuous dosing in fault conditions. Furthermore, a control override function allows immediate manual switching of dosing to OFF or constant ON, making it easier to conduct maintenance or emergency adjustments. Such dosing intelligence ensures consistent process quality with minimal manual intervention.

Easy Peripheral Connection for Seamless System Integration

Designed to streamline installation and interoperability, the BL981411 integrates quick‑connect terminal blocks to handle multiple system interfaces. Power supply terminals accommodate both the BL981411‑0 model (operating via included 12 VDC adapter) and the BL981411‑1 model (115 or 230 VAC 50/60 Hz). Sensor connectivity is straightforward: the BNC port accepts standard pH electrodes, while separate matching pin terminals help counter ground loop interference—eliminating erratic readings and potential sensor damage. Dosing relay contacts are isolated for secure pump or valve control, and wiring lugs are recommended for all external cabling to preserve connection integrity. Recommended probes include Hanna’s HI1001 PVDF body pH electrode, optimized for continuous flow‑through monitoring in industrial lines. By providing a platform for rapid integration of measurement, dosing, and communications hardware, the BL981411 reduces startup times for process engineers and limits system downtime when components are replaced.

Versatile Applications Across Industries and Environments

The Hanna BL981411 Mini pH Controller fits seamlessly across a broad spectrum of pH control applications. In water treatment plants, it maintains pH stability in filtration stages, neutralization tanks, or chemical dosing lines. Food and beverage producers implement the controller in production cycles to preserve flavor profiles, avoid spoilage, and ensure regulatory compliance. Aquaculture operations depend on stable pH for fish health and ecosystem balance, using the BL981411 for continuous monitoring and dosing in hatcheries or grow‑out systems. In chemical manufacturing, precise pH regulation is critical in synthesis reactions, cleaning processes, and waste treatment. Laboratories employ it for controlling pH in experimental setups, titration systems, or pilot plant equipment. The portability, panel‑mount capability, and compact footprint mean installation is possible even in constrained spaces, making it attractive to operators with limited panel real estate who still require accuracy and flexibility.

Intuitive Calibration and Setpoint Adjustment Capability

Operational simplicity is a highlight of the BL981411, allowing inexperienced technicians and seasoned engineers alike to calibrate and adjust parameters swiftly. Manual calibration is facilitated through the CAL trimmer, with procedures typically performed in pH 7.01 buffer solution to align readings precisely. The setpoint adjustment range spans the entire 0.0 to 14.0 pH scale, empowering users to tailor control thresholds to diverse chemical processes. The MEAS key returns the controller to measurement mode, while the SET key, paired with its trimmer, modifies target thresholds. After adjustments, the system automatically returns to normal operation—though manual return is available via MEAS key press. This method reduces calibration drift and ensures dosing actions begin only under stipulated conditions, safeguarding both chemical balance and equipment longevity. With real‑time LCD feedback during these actions, operators gain confidence in the instrumentation’s reliability.

Technical Specifications and Dimensional Details Highlighted

The BL981411 delivers specifications carefully aligned with real‑world process control needs. Measurement capabilities include a 0.1 pH resolution and ±0.2 pH accuracy at 25°C (77°F), leveraging an input impedance of 10^12 Ohm to maintain stable readings under challenging electrical environments. The dosing relay supports 250 VAC or 30 VDC loads up to 2A, ensuring compatibility with a wide range of dosing systems. The overtime protection system’s adjustable window from ~5 to 30 minutes adds preventive assurance for sustained dosing control. Physical dimensions measure 83 × 53 × 99 mm (3.3 × 2.1 × 3.9 inches), with operational weights of 200 g for the BL981411‑0 and 300 g for the BL981411‑1. Supplied accessories include mounting brackets, a transparent protective cover, and an instruction manual. These detailed specifications underscore the product’s ability to balance compactness, capability, and operator convenience for critical pH monitoring tasks.
