Hanna HI3818 | Carbon Dioxide (CO2) Chemical Test Kit (110 Tests)

Monitor the critical balance of your aquatic ecosystem with the Hanna HI3818, a comprehensive Carbon Dioxide (CO2) Test Kit designed for aquarists, fish farmers, and environmental researchers in Pakistan. Carbon dioxide is a vital parameter to control: in planted aquariums, it is the fuel for plant growth, but excess levels can suffocate fish. In natural waters, high CO2 often indicates pollution or decaying organic matter.

The HI3818 uses a simple Titration Method (drop count) to determine CO2 concentration. Unlike expensive digital meters, this chemical kit is cost-effective, easy to use, and requires no batteries or calibration. You simply add the reagent drop-by-drop to your sample until the color changes from colorless to pink. The number of drops used corresponds directly to the CO2 level.

This kit is versatile, allowing you to measure across three ranges (0-10 mg/L, 0-50 mg/L, and 0-100 mg/L), making it suitable for everything from delicate soft-water tanks to high-density aquaculture ponds. It comes with enough reagents to perform approximately 110 tests, offering exceptional value for regular monitoring.

Key Features of the Product

• Complete Testing Solution: Comes with everything you need: reagent bottles, two sample beakers, a calibrated syringe, and a clear instruction manual. No extra equipment is required.
• High Value (110 Tests): Includes enough chemical reagents to perform approximately 110 measurements, making the cost-per-test very low compared to digital alternatives.
• Simple Titration Method: Uses a standard phenolphthalein titration method. The distinct color change (clear to pink) makes it easy to read the endpoint visually.
• Three Measurement Ranges:
• Low Range: 0.0 to 10.0 mg/L (0.1 mg/L resolution)
• Medium Range: 0.0 to 50.0 mg/L (0.5 mg/L resolution)
• High Range: 0 to 100 mg/L (1.0 mg/L resolution)
• Compact & Portable: All components fit neatly into the rugged carrying case, making it perfect for field testing near rivers, lakes, or outdoor ponds.

Frequently Asked Questions (FAQs)

Q: Why is testing CO2 important?

A: In planted tanks, CO2 is fertilizer. You need to keep it around 15-30 mg/L for lush growth without gassing your fish. In fish farms, high CO2 (often from overcrowding) prevents fish from absorbing oxygen effectively, leading to stress or death.

Q: How accurate is this kit?

A: It is accurate to ±5% of the reading. For most aquarium and aquaculture applications, this titration method is the industry standard for accuracy vs. cost.

Q: What happens when I run out of chemicals?

A: You do not need to buy a new kit. You simply purchase the HI3818-100 Replacement Reagent Set from Kamadi Pakistan, which gives you another 110 tests.

Q: Is it safe for salt water?

A: Yes, the chemical reaction works in both fresh and saltwater. However, CO2 behaves differently in seawater (buffering), so ensure you understand the chemistry of your marine tank.

Q: Does it include a "Drop Checker"?

A: No. A "Drop Checker" is a passive glass device that stays in the tank for a rough estimate (Green/Yellow). The HI3818 is an Active Test Kit that gives you a precise numerical value (e.g., "22 mg/L") at that specific moment.
