pH sensor: 0 to 14
ORP sensor: -1500 to +1500 mV
Temperature Range
32 - 212 °F (0 -100 °C)
Operating Pressure
Hemi-bulb: 0 to 250 psig (0 to 17.24 barg)
Flat-bulb: 0 to 100 psig (0 to 6.89 barg)
Max Operating Pressure
(at retraction or insertion)
21 in. tube 64 psig (4.41 barg)
36 in. tube 35 psig (2.41 barg)

Features

  • Superior chemical resistance allows pH sensor and ORP sensor to withstand applications containing chlorine dioxide and a wide variety of organic solvents and oxidizing agents
  • Minimum maintenance due to robust reference technology helps ensure accurate pH/ORP measurement even in coating, fouling and poisoning processes
  • Helical reference pathway hinders reference poisoning and cracking resistant glass for a long pH/ORP sensor life
