Hanna HI98198 Optical Dissolved Oxygen Meter (Opdo™)

The Hanna HI98198 is a premier, rugged portable Dissolved Oxygen meter utilizing advanced Optical DO (Opdo™) technology. It eliminates the need for fragile membranes and electrolyte solutions entirely. Featuring an IP67 waterproof body, a built-in barometer, and an RFID-enabled Smart Cap that lasts a full year, it automatically calculates DO, BOD, OUR, and SOUR. It is the ultimate low-maintenance diagnostic instrument for environmental fieldwork, WASA inspectors, and massive commercial aquaculture farms.

Eliminate the frustrating maintenance of standard DO probes forever with the Hanna HI98198 Optical Dissolved Oxygen Meter. When WASA engineers and aquaculture managers in Pakistan test harsh environmental water or highly polluted ETP aeration basins, standard (polarographic) DO probes are a nightmare. The delicate PTFE membranes tear easily, the electrolyte fluid constantly needs refilling, and the probe requires a 15-minute electrical 'warm-up' before it can take a single reading.

The HI98198 revolutionizes field testing by utilizing Fluorescence Quenching Optical Technology. There are no membranes to stretch and no liquids to refill. You simply twist on a solid Smart Cap containing a luminescent dye. The meter emits a blue LED, and the oxygen in the water reacts with the dye optically, delivering instant, incredibly stable readings without requiring the water to be flowing. The cap features an integrated RFID Chip that tells the meter exactly when the cap expires (after one year of use). Housed in an indestructible IP67 Waterproof casing and featuring a 4000-point USB-C data log, it is the most reliable DO meter ever built for the field.

Key Features:

• Zero Membrane Maintenance: Completely bypasses the fragile, time-consuming PTFE membranes and electrolyte filling solutions used in standard DO meters.
• Flow Independent: Optical technology does not 'consume' oxygen during the test, meaning you get perfect readings even in completely still, stagnant water.
• Built-in Calculations: Automatically calculates Biological Oxygen Demand (BOD), Oxygen Uptake Rate (OUR), and Specific Oxygen Uptake Rate (SOUR) directly on the screen.
• Smart Cap Technology: The built-in RFID reader tracks the exact manufacturing date and first-use date, automatically warning the technician when the 1-year lifespan of the cap is complete.

Frequently Asked Questions (FAQs):

Q: What is the price of the Hanna HI98198 in Pakistan?

A: Visit Kamadi.pk for a formal corporate quotation. We supply this flagship optical meter to major WASA authorities and corporate aquaculture farms.

Q: Does it have an internal barometer?

A: Yes. The meter features a built-in barometer to automatically compensate DO readings for changes in atmospheric pressure, eliminating the need for manual altitude charts.

Q: HI98198 vs HI9146: Which should I buy?

A: The HI9146 is a classic polarographic meter that requires membranes, warm-up time, and careful maintenance. The HI98198 is an Optical (Opdo) meter that is instantly ready, incredibly rugged, and essentially maintenance-free.
