Hanna BL7916-1 pH Controller and Pump

Description

Integrated pH Meter and Dosing Pump

The Hanna BL7916‑1 pH Controller and Pump is a precision instrument that combines two advanced functionalities into one compact enclosure — a professional‑grade pH meter and a proportional chemical dosing pump. This combination allows operators to maintain precise pH levels in process applications where chemical addition is necessary to achieve a specific set point. By integrating measurement and dosing in one housing, the BL7916‑1 eliminates the need for separate monitoring and pumping devices, thus reducing installation complexity and saving valuable space. The front‑panel control layout facilitates immediate access to all operating features and adjustments. Its design is engineered for durability, ensuring dependable performance in demanding industrial or commercial environments. This product is globally recognized for its reliability and is available with an authenticity and quality guarantee from tpt24.com, the world’s leading online store for Hanna instruments, delivering anywhere in the world regardless of your location.

Easy Installation with Rugged Base Mounting

Ease of installation is a notable design advantage of the BL7916‑1. The unit is built on a rugged base with integrated mounting holes that securely anchor the device in place, whether in a plant, laboratory, or water treatment facility. All controls, input connections, dosing assemblies, and output terminations are located on the front panel, making installation straightforward and ongoing maintenance minimal. The installation process is made simpler thanks to the inclusion of discharge and suction valves, LDPE tubing, a 7‑meter feed length, and a power cord, all supplied as standard equipment. This inclusive set ensures that users can install and operate the controller immediately without needing additional components. It is well‑suited for facilities where access to the installation area is restrictive and where quick setup is advantageous to process continuity. Purchasing from tpt24.com secures not only the complete installation kit but also the assurance of receiving an authentic, high‑quality product with worldwide delivery.

Wide Range of Industrial Applications

The Hanna BL7916‑1 finds broad application in industries requiring precise pH regulation. It is extensively used in metal plating facilities where accurate pH control is essential for coating uniformity and surface treatment reactions. In wastewater treatment plants, it provides accurate chemical dosing to neutralize effluents before discharge. In general water treatment systems, whether municipal or industrial, it ensures that water meets required chemical balance standards. In swimming pools, the BL7916‑1 can maintain safe and comfortable pH levels, protecting both swimmers and equipment. Its proportional dosing capability makes it ideal for processes involving slow‑reacting chemicals, avoiding overdosing and costly corrections. By controlling dosage rates as the measured pH value approaches the set point, the system optimizes chemical usage. Professionals seek the BL7916‑1 for these applications not only for its technical precision but because purchasing through tpt24.com means securing authentic performance equipment, guaranteed and delivered globally.

Proportional Dosing for Chemical Efficiency

Central to the BL7916‑1’s operation is its proportional control function. This advanced feature modulates the pump’s stroke rate, slowing the dosing sequence as the monitored pH nears the target set points. This prevents overdosage and chemical wastage, which is particularly important when using expensive or environmentally sensitive reagents. Proportional dosing reduces the likelihood of severe process disturbances and ensures smoother, more gradual chemical additions that align with the natural response time of the process chemistry. Such control eliminates unnecessary and costly process corrections and is crucial for maintaining equilibrium in systems with slow chemical reaction kinetics. This intelligent dosing approach is a primary reason operators prefer the BL7916‑1 over conventional controllers. Acquiring this instrument through tpt24.com ensures you benefit from these dosing efficiencies with a model that is rigorously tested and supplied with quality assurance worldwide.

Reliable Pump Action with Minimal Mechanics

The BL7916‑1 employs a positive displacement solenoid pump mechanism with very few moving parts. This design significantly increases reliability compared to motor‑driven pumps with rotating parts, gears, or cams, which are prone to mechanical wear and failure. The absence of complex mechanical linkages means less downtime, lower maintenance costs, and greater operational stability. The solenoid approach ensures consistent dosing accuracy, regardless of chemical viscosity or system backpressure. Fewer mechanical components translate into smoother operation over extended service intervals. Users in continuous‑process industries benefit from this design because it maximizes uptime and minimizes intervention. When sourcing this model from tpt24.com, customers receive genuine Hanna equipment with guaranteed mechanical integrity, shipped securely worldwide.

Data Recording via Isolated Output

For enhanced process documentation and troubleshooting capability, the BL7916‑1 is equipped with a galvanically isolated 4‑20 mA recorder output. This allows operators to connect a chart recorder, data logger, or SCADA system directly to the unit for permanent performance records. The isolation prevents interference between systems and ensures signal integrity. By providing real‑time data capture during pH regulation tasks, operators can validate process compliance, detect anomalies promptly, and store evidence for regulatory or internal reporting. The front‑panel access to output contacts makes integration quick and efficient. Documentation is indispensable in industries where compliance with environmental or safety standards is mandatory. tpt24.com supplies the BL7916‑1 with full adherence to these specifications, guaranteeing accurate and reliable output functionality for global users.

Auxiliary Dosing for System Integration

The BL7916‑1 features auxiliary dosing contacts, allowing operators to connect supplementary devices such as mixers or priming pumps. These auxiliary devices activate only when the primary dosing pump is engaged, ensuring synchronized operation and preventing unnecessary energy consumption or wear. Such capability enables integrated chemical preparation systems where mixing, priming, and dosing steps are coordinated for efficiency and precision. This feature also supports complex dosing sequences in multi‑stage chemical treatment scenarios. By streamlining peripheral device activation, the BL7916‑1 reduces operational overhead while ensuring process integrity. Professionals sourcing from tpt24.com gain access to this advanced integration capability in an authentic, certified device, with expedited worldwide delivery.

Technical Performance and Environmental Tolerance

Technically, the BL7916‑1 offers a measurement range from 0.00 to 14.00 pH with a resolution of 0.01 pH and an accuracy of ±0.01 pH at 20°C. It offers user‑selectable acid or base dosing, handles isolated contacts rated at 2A, and withstands around one million strokes in service. Calibration is supported via offset and slope trimmers, giving operators fine control over measurement accuracy. The device operates in environments from 0°C to 50°C, up to 95% non‑condensing relative humidity, and requires 40W from a 110/115V supply. Measuring 221 x 142 x 181 mm and weighing around 5 kg, it balances compactness with mechanical robustness. Its design elements are specifically tailored for industrial resilience.
