OVERVIEW
The D-phi Series redefines accuracy, reliability, and ease-of-use for pH sensors.
Avoid headaches and wasted money with features that eliminate common installation and maintenance problems. This pH sensor has an extremely stable differential electrode that resists dilution and debris build-up. It also has a fast response time (96% accurate in less than 5 seconds) and cannot be poisoned by chemicals. Lastly, the sensor is designed for 10+ years of service and the electrode never needs replacement.
There are two types of backends are available depending on the mounting requirements;
- D-phi-s – for submersion and standpipe mounting
- D-phi-i – for inline mounting
Features
- Linear 4-20mA output
- Simple to use and easy to calibrate
- Accurate over long distances
- Compatible with a wide variety and dataloggers, PLCs, SCADA, and IoT systems
- Differential electrode technology
- Refillable electrode that never needs replacement
- Chemical-resistant titanium and Delrin® housing (PVDF available)
- Built-in 0-50°C temperature sensor (secondary 4-20 mA output)
- 3/4″ or 1″ NPT backend (depending on model)
- Fully submersible to 100 psi and 150°F
- Dry storage
- Automatic Temperature Compensation (ATC)
- 600 VDC electrical isolation
- 2-wire connection with Reversible Input Protection
Applications
- Process control
- Wastewater
