BlueLab PH Replacement Probe

Unfortunately pH Probes do not last forever as they age through normal use and will eventually fail. With good care and use (keeping the probe tip wet and cleaning once a month) you will extend its life.
 
The Bluelab pH Probe has a double junction reference which provides a longer life than many other pH probes and is a gel filled non-refillable probe, so apart from cleaning is maintenance free.

• Double-junction probe reduces reference contamination, extending longevity  
• Fully waterproof - not just water resistant  
• BNC connector allows use with all other compatible Bluelab products  
• 2-metre cable for measuring in hard-to-reach locations 
• Use the included storage cap with KCl to lengthen probe’s lifespan 
• Fast sensor response ensures quick and accurate measurements  
• Polycarbonate housing for long-lasting strength  
• Effective in solutions of 0.2 EC and above
