- Lab Grade pH Probe (OPEN BOX) - Neptune Systems
Neptune Systems tested many probes until they found a manufacturer that would provide long life as well as consistent and accurate performance. Lab grade probes are held to tighter standards and use higher quality materials allowing a longer life, and holding calibration longer than standard grade probes.
- Replace a worn out pH probe
- Purchase a pH probe to add to your Apex Lite System
- Purchase a pH probe to use with your PM1 Extension Module
The Neptune Lab Grade pH Probe is great for any monitor or controller that requires a BNC style connection with a high-quality probe. If you are buying a new controller that doesn't include a probe like the Apex lite, adding a new tank and need another probe, or just replacing your worn out old probe look no further.
Lab Grade probes will hold calibration longer, and generally just last longer than standard grade pH probes.
Note: Calibration solution not included. We suggest ordering multiple packets of calibration solution to have on hand and calibrating every 60-90 days for reliable results.
