Frequently Asked Questions

Are YSI water quality meters waterproof?

Yes, YSI water quality meter kits are IP67-rated, offering protection against water ingress. It allows the meter to withstand immersion up to 1 meter for 30 minutes.

What is the measurement unit of the dissolved oxygen meter for water?

    Dissolved oxygen is typically measured in milligrams per litre (mg/L). Different levels of dissolved oxygen are listed below:
    • 0-2 mg/L: Not enough oxygen to support life.
    • 2-4 mg/L: Only a few fish and aquatic insects can survive.
    • 4-7 mg/L: Good for many aquatic animals, low for cold water fish.
    • 7-11 mg/L: Suitable for most stream fish.

How does temperature affect dissolved oxygen levels in water?

Warmer water temperatures result in lower dissolved oxygen levels due to decreased oxygen solubility. Elevated temperatures can also accelerate metabolic rates and biochemical reactions in water. Reduced dissolved oxygen levels can harm aquatic habitats and organisms, potentially leading to hypoxic conditions. Monitoring dissolved oxygen levels is essential to maintain water ecosystem health and habitat quality.
