Q22PX pH / ORP Universal Sensors

ATi’s Q22 specialty pH/ORP universal sensors are designed for use with all non-ATi analyzer systems and generic panel meters, allowing end-users to utilize the same robust features of the standard ATi Q25 sensors.

Replace unreliable sensors & cut maintenance costs

ATi’s Q22 PX universal or loop powered sensors emulate standard, non-amplified combination sensors and are designed to interface with all non-ATi pH/ORP analyzers. The universal sensors require no power supply as the preamplifier is powered by an internal lithium battery. The pH sensor outputs a mV signal in the range of either -500 to +500 mV or 0 to 2 VDC; both are linear over the 0 to 14 pH range. The ORP (Oxidation Reduction Potential) sensor outputs an mV signal that ranges from -1000 to +1000 mV.

These sensors may be used as replacement sensors for use with all non-ATi analyzers. The Loop-powered sensors require an external 7-30 VDC power supply and provide a 4-20 mA output signal for direct connection to generic panel meters, data acquisition systems, or other devices that accept a current input. The sensor includes integral temperature compensation of the pH signal, so no temperature output is provided. The sensor output is uncalibrated, therefore, the receiving instrument must be capable of providing user calibration of the pH or ORP signal on a periodic basis.
