1 Specialty pH & ORP Sensors .. Model Q22 The Q22 Specialty pH/ORP sensors are designed for use with allnon-ATI analyzer systems and generic panel meters, allowingthese end users to utilize the same robust features of the stan-dard ATI Q25 sensors. The sensors are classified as eitherUniversal or Loop-Powered, depending on the output Universal sensors emulate standard, non-amplifiedcombination sensors and are designed to interface with allnon-ATI pH/ORP analyzers. The sensors require no powersupply as the preamplifier is powered by an internal lithiumbattery. The pH sensor outputs a mV signal in the range ofeither -500 to +500 mV or 0 to 2 VDC; both are linear over the0 to 14 pH range. The ORP sensor outputs a mV signal thatranges from -1000 to +1000 mV. These sensors may be used asreplacement sensors for use with all non-Quantum analyzers.

2 The Loop-powered sensors require an external 7-30 VDCpower supply and provide a 4-20 mA output signal for directconnection to generic panel meters, data acquisition sys-tems, or other devices that accept a current input. The sen-sor includes integral temperature compensation of the pHsignal, so no temperature output is provided. The sensoroutput is uncalibrated, therefore, the receiving instrumentmust be capable of providing user calibration of the pH orORP signal on a periodic Sensor:The reference element is asecond glass pH electrode immersed in a reference buffersolution. This glass reference system allows the sensor tobe used in applications that poison conventional pH orORP or 316SS Sensor Body Construction: All sensorhousings are constructed of either PEEK , a highperformance thermoplastic that provides outstandingmechanical strength and chemical resistance, or 316stainless steel.

3 Replaceable Sensor Saltbridge: A large volume, dualjunction saltbridge is used to maximize the in-service timeof the sensor. The replaceable saltbridge allows for easyand inexpensive sensor regeneration. Integral Preamplifier:The integral preamplifier isencapsulated in the body of the sensor. This creates a lowimpedance signal output which ensures stable readings inharsh environments, and maximizes the distance betweensensor and analyzer. Multiple Electrode Types: Sensor electrodes are user-specified to ensure measurement reliability and maximumsensor lifetime. The type of pH electrode can be selectedfor optimal performance.
