Available Cable Lengths
4-meter (12-foot) cable: Ideal for smaller ponds and shallow monitoring applications.
10-meter (30-foot) cable: Perfect for deeper ponds and bottom-water sampling in large systems.
FAQ
Q: How often should I calibrate?
A: Calibrate before each use or at least weekly for best accuracy.
Q: What's the difference between cable lengths?
A: Only cable length differs. Choose 4-meter for ponds up to 10 feet deep, or 10-meter for deeper systems.
Q: Can I use this in saltwater?
A: Yes, the manual salinity compensation allows use in both freshwater and brackish water.
Q: What's the ideal oxygen level for koi?
A: Most pond fish thrive above 6-7 mg/L. Levels below 4 mg/L cause stress.
Q: What does it measure?
A: Dissolved oxygen in mg/L (equivalent to ppm) and water temperature.
