Overview
This is Neptune Systems' pH 7.00 calibration fluid, the mid-point reference solution used to calibrate the pH probe on your Apex controller so it reads accurately.
Used alongside the pH 10.00 solution, it forms the second point of a proper two-point calibration, which is what keeps your Apex's pH readings trustworthy over time.
Key features
- Precision-buffered to pH 7.00
- Purpose-made for Neptune Systems Apex pH probes
- Ready to use straight out of the bottle
Who it's for
Apex owners who want accurate pH monitoring and dosing decisions based on reliable data, across any tank size.
Setup & tips
- Use in combination with the pH 10.00 solution for a full two-point calibration
- Rinse the probe with RO/DI water between the two solutions to avoid cross-contamination
- Don't reuse solution that's been poured out and left exposed — start with a fresh sample each time
- Store the bottle sealed and away from direct sunlight to preserve accuracy
