Gel-Filled Plastic pH Electrodes Long & thin

Rugged and versatile

• Extra long and thin: body measures 7 in. long (178mm); only 0.25 in. (6mm) in diameter
• Rugged polymer construction for handheld use
• Filled with gelled 4M KCl saturated with AgCl electrolyte; never needs refilling
• Endcap seal keeps membrane moist and ready
• Porous ceramic single junction

Fast and accurate

• Accuracy, ±0.05pH at 25°C (77°F)
• Efficiency, >95%
• Sodium Ion error, <±0.05pH at 25°C (77°F)
• Response time, 30 seconds

• Aqueous samples in the classroom or in the field
• Anywhere rough handling and breakage are problems, and maintenance is difficult
• Small samples in long, narrow vessels
