F12 Toxic Gas Transmitter

ATi's F12 Toxic Gas Transmitter is designed to measure toxic gases and oxygen in hazardous locations requiring an Intrinsically Safe (IS) device. A non-IS version is also available for non-hazardous locations. Each version utilizes a digital communications protocol.


  • Accepts upt to 32 different gas sensors

  • Toxic & Ambient (Oxygen) Gas, Electrochemical Sensors

  • Loop-powered, or AC powered with relays

  • Auto-Test Sensor, "Self-Test" option

C12-17 Combustible Gas Transmitter

Water quality monitors for clean / drinking water and wastewater treatment applications.

We offer a measurement system for all your water monitoring requirements utilizing amperometric membrane and selective ion electrode technologies.  Many of our systems do not require reagents, thus reducing operating costs.

pH Monitor
Q46P/R pH/ORP Monitor

Measurement and control of pH is important in a wide variety of industries. Water and wastewater, boiler feed water, high purity water, food processing wash water, chemical plant cooling water, and many other aqueous systems require reliable pH monitoring.


ATI’s Model Q46P pH monitor provides the combination of durability, accuracy, and versatility required for virtually any pH monitoring or control application. The Model Q46R provides the same reliable monitoring for Oxidation-Reduction Potential (ORP) applications.


ATI’s Q46 platform represents the latest generation of monitoring and control systems. Control features have been expanded to include an optional 3rd analog output or an additional bank of low power relays. Digital communication options now include Profibus IP, Modbus RTU, or Ethernet IP variations.


ATi's C12-17 Combustible Gas Transmitter is a stand-alone gas transmitter designed to detect potentially hazardous concentrations of combustible gases in ambient air. Gases and hydrocarbon vapors such as methane, propane, butane, gasoline, toluene, hydrogen, and many others can be reliably monitored in process buildings, analyzer enclosures, pump stations, and gas compressor stations. In fact, anywhere gases or vapors may build up to explosive levels can be readily monitored using this transmitter.

C16 PortaSense II Portable Gas Leak Detector

One detector for many gases...

ATIs Series C16 PortaSens II Portable Gas Leak Detector is a versatile tool for performing regular leak checks in gas storage areas, around process equipment and piping, or in confined spaces prior to entry. Designed for easy one-hand operation, the gas detector contains an internal sample pump and a flexible sampling wand to allow pinpoint location of the source of leakage. A large character display insures that measured values are easily visible, and a back-light for the display insures readability in low or no light conditions.

pH Monitor
Q46H Residual Chlorine Monitor

ATIs Model Q46H/62-63 Residual Chlorine Monitor is an upgraded version of our proven Q45H Chlorine Monitor system for continuous monitoring of free or combined chlorine. Monitor capabilities have been expanded to include options for a third analog output or additional low power relays. Digital communication options for Profibus, Modbus, and Ethernet are available with this monitor.

The Q46H Chlorine Monitor (Analyzer, Transmitter) system uses a polarographic membraned sensor to measure chlorine directly, without the need for chemical reagents. When needed, automatic pH compensation may be added for increased free chlorine measurement accuracy. Systems are available to provide outputs for chlorine, pH, and temperature to allow easy Contact Time (CT) calculations.

Q46H systems are economical to purchase, easy to maintain, and provide long term accuracy and reliability for your chlorine monitoring needs.



If you spend money on reagents every month to run & maintain another manufacturer's monitor, you can afford to purchase a brand new ATi Q46H with less maintenance & operational costs.
