Model Q - Gas Monitors and Water Quality Monitors

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.

2 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. 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.

3 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.

4 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.
