PEEK sensor offers a lower cost solution than previous versions for submersion applications. Sensor fits into the same space and has similar specs, making it a drop-in replacement for the existing sensor. Electrodeless sensor design measures accurately over a wide dynamic range and can be used in applications from 50(S to 1000mS. Electrodeless sensor design resists fouling, providing longer unattended service. Walchem Corporation 5 Boynton Road, Hopping Brook Pk. Holliston, MA, 01746
