HI3810 | Hanna Dissolved Oxygen Test Kit 0.0-10.0 mg/L

Ensure the survival of your aquatic life with the Hanna HI3810 Dissolved Oxygen Chemical Test Kit, a portable and reliable monitoring solution for aquaculture, environmental research, and water treatment in Pakistan. Dissolved Oxygen (DO) is the single most critical parameter in water quality; low levels can lead to immediate fish kills, while high levels can cause gas bubble disease.

The HI3810 utilizes the Modified Winkler Titration method to measure Dissolved Oxygen levels from 0.0 to 10.0 mg/L (ppm) with a resolution of 0.1 mg/L. Unlike expensive digital meters, this kit uses a simple chemical reaction that turns the sample yellow, followed by a drop-by-drop titration until the color disappears. It is fully self-contained in a rugged carrying case, requiring no batteries or calibration, and includes reagents for approximately 110 tests, making it the standard choice for field biologists and fish farmers.

Frequently Asked Questions:

• Q: Is this easier to use than a digital meter?

  • A: It requires a bit more manual work (counting drops) than a digital probe, but it is cheaper and maintenance-free (no membranes to replace, no electrolyte to fill, no calibration required). It is excellent for spot checks in the field.

• Q: How does the test work?

  • A: You add reagents to the sample bottle to "fix" the oxygen, which creates a yellow precipitate. You then dissolve this precipitate with acid and titrate with Sodium Thiosulfate until the solution turns clear. The amount of titrant used equals the DO concentration.

• Q: Can I buy refill reagents?

  • A: Yes. Once you have used the included reagents, you can purchase the HI3810-100 replacement reagent kit (110 tests) to continue using the original glass bottle and calibrated hardware.
