Hanna HI9147 | Portable Galvanic Dissolved Oxygen Meter (Aquaculture Specialist)

Optimize your aquaculture yield and protect your stock with the Hanna HI9147, a rugged Portable Dissolved Oxygen (DO) Meter designed specifically for fish farming and environmental monitoring in Pakistan. While standard DO meters often require a frustrating 15-20 minute "warm-up" period before they can be used, the HI9147 features a superior Galvanic Sensor. This technology allows you to turn the meter on and take an accurate reading instantly, saving critical time when checking multiple ponds or tanks.

The HI9147 is built for the "wet and wild" conditions of hatcheries. It is water-resistant and features a backlit LCD, ensuring you can read oxygen levels clearly even during early morning or late-night checks. Crucially for brackish water farming (like shrimp), the meter allows for Manual Salinity and Altitude Compensation, ensuring that your oxygen readings are corrected for salt content and elevation—factors that significantly alter oxygen solubility.

Supplied with the durable HI76409 Galvanic Probe (available with various cable lengths), this meter is the industry standard for fish farmers who need a "grab-and-go" solution that just works.

Key Features of the Product

• Instant Ready (Galvanic Probe): Unlike polarographic probes that need warm-up time, the galvanic sensor is always polarized and ready to measure the moment you switch it on.
• Designed for Aquaculture: Rugged, water-resistant casing protects the electronics from splashes, humidity, and wet hands common in fish farming environments.
• Manual Salinity Compensation: Allows you to adjust the meter for salt water (0 to 51 g/L), ensuring accurate DO readings in shrimp ponds and brackish creeks.
• Altitude Compensation: Vital for users in northern Pakistan or elevated regions, allowing correction up to 4000 meters to account for lower atmospheric pressure.
• Backlit LCD Display: A bright backlight makes it easy to record data in low-light conditions, such as indoor hatcheries or night-time monitoring.
• Simple Maintenance: The probe uses easy-to-replace HDPE membrane caps (HI76409A/P) and electrolyte solution, making routine maintenance quick and inexpensive.

Frequently Asked Questions (FAQs)

Q: Why is a Galvanic probe better than a Polarographic one?

A: Speed. A Polarographic probe needs 15-20 minutes to "polarize" (warm up) every time you turn the meter on. A Galvanic probe (like in the HI9147) has no warm-up time. You turn it on, and it reads immediately. This is huge for field workers visiting multiple sites.

Q: Can I use this for seawater?

A: Yes. The HI9147 has a manual Salinity Compensation feature. You can dial in the salinity (in ppt) so the meter calculates the correct oxygen level for salt water (salt water holds less oxygen than fresh water).

Q: How often do I need to calibrate?

A: For critical aquaculture, we recommend a simple 100% Air Calibration daily. It takes seconds: just hold the probe in moist air and adjust the "100%" trimmer knob until the screen reads 100%.

Q: Is the probe cable length customizable?

A: The HI9147 is typically sold with a specific cable length attached (e.g., HI9147-04 has 4 meters, HI9147-10 has 10 meters). You must choose the model with the correct cable length at the time of purchase as it is hard-wired.

Q: What maintenance does the probe need?

A: Change the electrolyte solution inside the cap once a month and replace the membrane cap every 2-3 months (or if it gets damaged/fouled).
