AP300 pH/Redox Sensor
Brand: ABB GroupThe AP300 sensor is the perfect starting point for pH or redox (ORP) measurements.
Economical in outlay, yet powerful enough for the majority of standard applications, these PPS (Ryton) and PVDF-bodied sensors operate to 105° C (221° F) and 6 bar (90 psi).
Backed by a gel-filled, no maintenance electrolyte, bulb and flat-glass versions ensure rugged performance and exceptional resistance to in-line coatings.
With flexibility of mounting methods, the range provides uncomplicated, effective technology enabling on-site customization.
Features- Long life
- large PTFE junction provides resistance to fouling
- double junction with gelled electrolyte provides better-defined junction potentials, creating an inherently-stable reference junction that is resistant to poisoning
- High accuracy
- specially formulated, low sodium-error glass for accuracy at high pH
- temperature sensor positioned perfectly to compensate for measurement and reference element temperature, ensuring rapid compensation and process temperature tracking
- High reliability
- operates up to 105° C (221° F) and 6 bar (90 psi) @ 25° C (77° F)
- fouling-resistant flat glass available
- High flexibility
- suitable for a wide range of applications
- available for insertion, immersion, flow-through and hot-tap
- standard- and blue-glass options
- bulb and flat-glass options
- Economical
- cost-effective
- long life
- highly reliable
