Micro Volume pH Monitor UP-100


Redevelops HORIBA's founding pH measurement technology using new ultra-small capillary electrode. HORIBA's UP-100 affords ultra-low sample consumption of just 500 uL/measurement, enabling continuous pH monitoring for a variety of critical manufacturing processes that include Semiconductor (Cleaning, Etching and Plating); Chemical Manufacturing, Bio, Pharm, Food Processing, etc.
Designed for 6 month continuous operation without operator intervention for minimizing downtime


  • Consumes only 500μL/minute, Maximum 30 mL/hour.
  • Real-time measurement
    One minute measurement interval (minimum)
  • Includes internal storage of standard solutions for automatic calibration and replenishment of KCl
