Neptune Systems Lab Grade pH Precision Probe
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.
