Hanna HI9811-51 Portable pH/EC/TDS/Temperature Meter – Agriculture

The Hanna HI9811-51 is a rugged, portable multiparameter meter specifically engineered for agriculture, greenhouses, and hydroponics. It measures pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), and Temperature using a single 4-in-1 amplified probe (HI1285-51). Featuring manual analog calibration dials and a fixed 0.5 EC to TDS conversion factor, it is the ultimate field tool for managing liquid fertilizer solutions.

Streamline your crop nutrition management with the Hanna HI9811-51 Portable Multiparameter Meter. For commercial hydroponic growers and greenhouse managers across Pakistan, mixing the perfect liquid fertilizer is a daily challenge. You must balance the pH so plants can absorb nutrients, while simultaneously checking the EC/TDS to ensure the fertilizer isn't too weak or strong enough to burn the roots. Juggling three separate meters is inefficient and prone to error.

The HI9811-51 solves this by utilizing the HI1285-51 Amplified 4-in-1 Probe. You simply dip one probe into your nutrient reservoir to read pH, EC (up to 6000 µS/cm), TDS (up to 3000 ppm), and Temperature. Because greenhouses are filled with massive water pumps and HID lighting ballasts, standard meters suffer from electrical interference. The built-in amplifier completely shields the probe from this noise. Furthermore, it features "old-school" Manual Calibration Dials, allowing agronomists to quickly tweak the calibration using a screwdriver without navigating complex digital menus.

Key Features:

• 4-in-1 Efficiency: Measures pH, EC, TDS, and Temperature simultaneously, eliminating the need to buy and maintain separate meters.
• Amplified Noise Shielding: Guarantees dead-stable readings even when standing next to heavy 3-phase agricultural water pumps.
• Manual Analog Calibration: Front-mounted trimmer dials allow for rapid, physical calibration adjustment in the field.
• Automatic Temperature Compensation (ATC): The built-in sensor instantly corrects EC and TDS readings for thermal variations, ensuring accurate nutrient dosing.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI9811-51 in Pakistan?

A: Visit Kamadi.pk for current B2B and retail pricing. We supply authentic Hanna agricultural kits to farmers nationwide.

Q: Does the probe need to be refilled?

A: No. The HI1285-51 probe is a gel-filled, maintenance-free electrode. You only need to keep the tip clean and stored moist.

Q: How do I clean fertilizer off the probe?

A: We highly recommend using the Hanna HI700661 Agricultural Cleaning Solution weekly to dissolve the sticky mineral salts that coat the sensor.
