Description

Technical Overview: Hanna HI9811-51 Portable Multiparameter Meter

The Hanna HI9811-51 is a specialized, water-resistant portable pH/EC/TDS/temperature meter engineered for high-precision water quality analysis. This digital multiparameter water meter simplifies laboratory and industrial workflows by integrating four essential testing functions into one compact device. It eliminates the need for multiple instruments, allowing professionals to monitor water quality with efficiency and accuracy.

Advanced Sensor Technology for Precision Measuring

At the heart of the Hanna HI9811-51 is the HI1285-51 multiparameter probe. This probe features a robust polypropylene body that houses an amplified pH electrode, an amperometric EC/TDS sensor, and a built-in temperature sensor. The pre-amplified design of the Hanna pH meter electrode prevents signal interference from electrical noise, humidity, or external electromagnetic fields commonly found near pumps and motors.

• Temperature Range: 0.0 to 70.0 °C (±0.5 °C accuracy)

• Calibration: Manual, 1-point offset (pH) and 1-point slope (EC/TDS)

• Temperature Compensation: Automatic from 0 to 70 °C (β = 2%/°C)

Industrial Use-Case: Empowering Bangladesh’s Sector Performance

In the industrial landscape of Bangladesh, consistent water quality is a critical factor for success. The Hanna HI9811-51 serves as an indispensable tool across various sectors, ensuring that production lines remain compliant and efficient.

Greenhouse and Hydroponic Management

Modern agriculture in Bangladesh relies heavily on hydroponics. The Hanna TDS meter and Hanna EC meter functions allow growers to monitor nutrient solution concentrations precisely. By maintaining optimal conductivity levels, users can prevent plant stress and maximize crop yield, making it the best multiparameter meter for hydroponics in Bangladesh.

Water Treatment and Environmental Monitoring

For facilities involved in boiler feed water, cooling towers, or general wastewater treatment, the HI9811-51 Hanna Instruments device provides reliable, real-time data. Its waterproof design and durable probe construction ensure it performs consistently in demanding field conditions, serving as a trusted industrial water testing equipment asset.

Maintenance and Calibration Guide

To ensure long-term accuracy, proper maintenance of your water analysis probe is essential. Regular calibration keeps your readings within strict quality standards.

How to Calibrate Hanna HI9811-51

1. Preparation: Use fresh calibration solutions. Place the probe in the specific buffer solution, ensuring it is submerged 4 cm deep.

2. pH Calibration: Press the pH key. Use the offset trimmer (knob) to adjust the reading to match the temperature-corrected value of the pH 7.01 buffer.

3. EC/TDS Calibration: Press the EC or ppm key. Use the slope trimmer (knob) to adjust the reading to 1413 µS/cm or the equivalent TDS value.

4. Frequency: Calibrate monthly, after probe replacement, or after measuring aggressive chemical samples.

Prolonging Probe Life

• Storage: Always store the probe in HI70300 storage solution to keep the junction moist.

• Cleaning: If readings become unstable, soak the sensor in a specialized cleaning solution (e.g., HI700661) for 5 minutes.

• Inspection: Check the cable for cracks and ensure the DIN connector is free of corrosion.
