The construction of these electrodes allows them to withstand the high 
temperature of sterilization and fouling caused by most biological 
media. These electrodes are rated for 40.5 psi @ 131°C (268ºF) and 
deliver long-term stability despite minimum maintenance.
Note: Optional PT100 or PT1K ATC (builtin temperature compensation) is available 
for PHE-5431-10 and PHE-5432-10; add 
suffix “-PT100” and “-PT1K” to model 
number and $40 to price.
