Analytical Control Instruments GmbH (ACI) products

The photoionization detector module PIM CPN is an OEM module to detect volatile organic compounds with an ionization potential < 10.6 eV in standard version (optional 10.0 eV and 11.8 eV available). With its electronics and microcontroller as well as the combined humidity / temperature sensor, it provides a flexible and easy to use adaptation into your measurement system. The module comes with a built in linearization and temperature / humidity compensation and a full digital interface. The sensor chamber design comes with a barometric and flow sensor for later compensation and gas flow monitoring.

The Stationary Photoionization Detector SPID2 is a continuously measuring detector for volatile organic compounds (VOCs) with an ionization potential less than 10.6 eV. The use of new technologies for the excitation source and the sensor allows a high stability of measurement and longer maintenance intervals. An integrated active carbon filter and the circuit sampling an automatic fresh air setup and automatic calibration are controlled. The unit is designed and approved for use in explosive atmospheres. The SPID2 uses a high stable hollow cathode lamp with an energy of 10.6 eV as ionization source. This lamp provides with its ceramic discharge channel a highly stable UV output and a lifetime of 8,000 h (typically 15,000 hours and more). The special design of the sensor in conjunction with automatic feeding of pollutant-free air through an activated carbon filter results in longer maintenance intervals.

The PIDS3 – Smart Photoionisation Module Version 2 is an OEM module to detect volatile organic compounds with an ionisation potential less than 10.6eV. With its built-in electronics and microcontroller as well as a combined humidity/temperature sensor it provides a flexible and easy to use adaption into your measurement system.

The Portable PID is a new generation of portable Photoionization Detectors to detect volatile organic compounds (VOCs) with an ionisation potential less than 10.6 eV. It presents the known measuring properties from the PPM in an entirely revised, modern concept. The state-of-the-art PID technology in combination with the experience of two decades of instruments construction provides the professional user with an instrument for highest sensitivity and robustness. Designed for field use, the Portable PID can be used for person-related as well as stationary measuring tasks in which hazardous substance concentrations (gases, vapours) in air (working environment, inner rooms, soil air, environment) must be monitored.

The LAB PID is a stationary Photoionisation measuring system for permanent monitoring and measurement of a broad range of total volatile organic compounds (VOC). A hollow cathode lamp (10.6 eV) will be used as ionization source. This lamp provides a high stable light output and a guarantied life time for more than 5000 hours (typical up to 10000 hours).
