Portable Dissolved Oxygen Meter DO Tester with Replaceable Probe ATC 0-20mg/L Wa

Product Description

Why does your fish pond/seafood require a dissolved oxygen meter?

Low dissolved oxygen can cause floating heads, decreased appetite, growth arrest, and even death in fish and shrimp.
This dissolved oxygen meter helps you monitor dissolved oxygen levels in real-time, avoiding losses caused by water quality issues.

⭐ Core functional advantages

● Dual mode reading: mg/L+% saturation

✔ Mg/L (ppm) mode - suitable for fish ponds, hydroponics, and aquariums
✔ % Saturation - used for scientific research, testing, or professional breeding farms

● Automatic temperature compensation (ATC) 0-50 ° C

Changes in water temperature can affect dissolved oxygen, and this instrument can automatically calibrate to ensure stable and reliable readings.

● High sensitivity replaceable probe (with protective cover)

The probe adopts professional electrochemical sensing technology:
✔ fast response
✔ High accuracy
✔ Long service life
✔ Replacing the probe does not require replacing the entire machine, resulting in lower costs

● Battery powered, portable

4 x AG-13 (1.5V) button battery is sufficient for use, making field/fish pond visits more convenient.
For transportation safety, the package does not contain batteries. Please install batteries before use

🟢 Correct usage method

✔ During measurement, it is necessary to cover the probe with a protective cover (correct)
✘ Do not open the protective cover for bare probe measurement (incorrect)
The protective cover already contains a permeable membrane, which is a necessary structure for DO measurement.
