BlueTechFins - Nitrite Sensor (NO₂⁻)

Measures nitrite ion (NO₂⁻) concentrations to detect this highly toxic intermediate compound that can harm aquatic organisms even at very low levels (0.1-0.5 ppm).

• Health Monitoring: Prevents fish stress, illness, and mortality from nitrite poisoning
• Biofilter Assessment: Tracks nitrification process and bacterial colony health
• System Management: Guides water changes, feeding rates, and stocking densities
• Early Warning: Detects system overload or biological filter failure

• Prevents "brown blood disease" in fish
• Supports healthy biofilter establishment
• Enables proactive management before crisis situations
• Reduces fish mortality and production losses

Installed in culture tanks, biofilter outlets, and recirculation systems for continuous monitoring and immediate alerts when unsafe nitrite levels are detected.
