pH Electrode – Lab Grade
Accurate and durable pH electrode, in ‘Lab Grade’ that can be connected to the PM1 module.
Buy this electrode if you:
Want to replace a worn out pH electrode. A Lab Grade pH electrode lasts approximately 24 months.
Want to use a 2nd pH electrode in your system (for example for a calcium reactor). Buy a PM1 module here.
Have a spare electrode on the shelf.
Lab Grade electrodes last longer, give more accurate readings, stay calibrated longer and need to be replaced less often.
