ISFET solid-state pH sensor plus reference and ATC probe—in one tough epoxy body

  • Use directly with accumet™ AR, AB15, AP15P or BASIC
  • Replaces fragile glass pH-sensing membrane with rugged, solid-state Ion-Selective Field Effect Transistor (ISFET)
  • Reference cell contains gelled Ag/AgCl electrolyte, for high performance with low maintenance
  • Porous junction provides extra-long service
  • Built-in temperature probe for accurate measurements in a minimum of space
  • Durable epoxy body takes all the rough handling you can dish out
  • Nonglass sensor remains unscathed, even by abrasive soil samples encountered in environmental testing
  • Gives you high reproducibility, excellent stability and fast response time without risk of breaking a glass body or delicate glass bulb
A cost-effective solution for high-risk applications
  • For aqueous solutions, viscous samples, even semisolids
  • For situations where breakable glass electrodes could be hazardous—food, beverage and pharmaceutical processing, for example
  • Ideal both for rapid, routine, high-workload measurements and for reliable measurement of difficult samples in environmental, pharmaceutical, food and beverage applications
  • Rapid, reproducible results even in thick, glutinous samples: simply wipe unbreakable sensing element to remove sticky, viscous substances—even peanut butter and bread dough—to eliminate sample carryover

For use with a variety of meters

  • accuFet electrode 13-620-755 with DIN connector is for use with accumet Research (AR) and accumet Basic (AB) benchtop models—no adapter needed
  • accuFet electrode 13-620-758 with mini-DIN connector is for use with discontinued BASIC series meters directly
  • accuFet electrode 13-620-AP20 with waterproof Twist-lock connector is for use with discontinued accumet portable meters AP25 and AP15
