These highly accurate sensors utilize a preamplifier to ensure stability over longer distances, and to eliminate potential noise problems thereby ensuring accurate repeatable readings.
In addition, these reliable sensors feature an integral temperature sensor to ensure accurate and rapid automatic temperature compensation.
Several choices of sensors are available, in 1/2" MNPT or 3/4" MNPT, depending on the demands of the application. The basic pH sensor utilizes the standard round glass electrode with a single reference junction. The basic ORP sensor utilizes a Platinum electrode with a single reference junction.
NOTE: Heavy Duty "F" model sensors may be installed in ANY direction including inverted.
SPECIFICATIONS
Temperature Compensation: Integral temperature sensor provides automatic TC to 25°C between 0 - 100°C/32 - 212°F.
Pressure/Temperature Limits: P72S: Intermittent use up to 50 psi/690 kPa 100°C/212°F. High Temperature models available.
Cable: 5 wire, 24 ga. shielded, 10 ft./3 meters standard. 25 and 100 ft./8 and 30 meter lengths available.
Material: 1/2" MNPT: CPVC body. 3/4" MNPT: Ryton®** body.
Dimensions: P72S typical: overall length 165 mm/6.5 in., body 127 mm/5 in., electrode length 19 mm/.75 in.
NOTE: All pH and ORP sensors are life limited. For this reason, it is recommended that extra sensors be kept on hand for all process applications. To obtain the maximum life, ALWAYS store sensor in pH/ORP Sensor Storage Solution when not in use. DO NOT allow sensor to dry out.
