Hanna HI9146 Portable Dissolved Oxygen Meter – Polarographic

The Hanna HI9146 is a highly precise, microprocessor-based portable Dissolved Oxygen meter utilizing a laboratory-grade Polarographic probe. It delivers elite accuracy (±1.5% F.S.) for demanding industrial and environmental applications. Featuring an Auto-Endpoint mode to freeze stable readings, Altitude/Salinity compensation, and a Battery Error Prevention System (BEPS), it is the standard compliance instrument for WASA authorities and wastewater treatment facilities.

Achieve absolute laboratory-grade precision directly on the factory floor with the Hanna HI9146 Polarographic Dissolved Oxygen Meter. While the instant-on galvanic meters are favored by fish farmers, environmental scientists and industrial engineers managing massive Effluent Treatment Plants (ETPs) in Pakistan require a higher standard of regulatory compliance. To ensure the biological scrubbing microbes in a wastewater aeration basin are functioning, the oxygen data must be legally defensible.

The HI9146 utilizes a highly refined Polarographic Measurement System (Clark-type sensor). While it requires a brief polarization time upon startup, it rewards the operator with unmatched stability, precision, and an incredibly long probe lifespan. The meter features an Auto-Endpoint Mode that automatically freezes the digital reading on the backlit LCD the moment the measurement fully stabilizes, ensuring that untrained technicians don't record the data prematurely. It is the ultimate tool for heavy industrial environmental auditing.

Key Features:

• Clark-Type Polarographic Probe: The global engineering standard for highly precise, repeatable dissolved oxygen measurements in complex industrial wastewater.
• Auto-Endpoint Freezing: Eliminates human error by automatically locking the display when the chemical reading is mathematically stable.
• Altitude & Salinity Compensation: Allows technicians to manually adjust the atmospheric and saline variables to ensure flawless oxygen saturation calculations.
• Battery Error Prevention (BEPS): Automatically shuts down the meter if battery voltage drops too low, preventing the recording of corrupted QA data.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI9146 in Pakistan?

A: Check Kamadi.pk for competitive B2B rates. We support commercial municipal teams and ETP operators with officially certified Hanna diagnostic tools.

Q: HI9147 (Galvanic) vs HI9146 (Polarographic): Which should I buy?

A: If you are a fish farmer needing instant, rapid checks across 20 ponds, buy the HI9147. If you are an industrial engineer monitoring a chemical aeration basin who needs maximum probe lifespan and lab-grade stability, buy the HI9146.

Q: What is the calibration process?

A: It features a simple one or two-point calibration. You can calibrate to 100% simply by holding the probe in saturated air, and to 0% using Hanna's HI7040 zero oxygen solution.
