The new generation of portable photoionization measuring devices.

The Portable PID handheld is a new generation of portable photoionization detectors for the detection of volatile organic compounds (VOCs) with an ionization potential < 10.6 eV, which presents the measurement properties known from the PPM in a completely revised, modern concept. The ultra-modern PID technology, combined with the experience of 20 years of measuring device construction, offers the professional user a measuring device with maximum sensitivity and robustness. Designed for field use, the Portable PID is suitable for both personal and stationary measuring tasks where hazardous substance concentrations (gases, vapours) in the air (working environment, indoor, soil gas, environment) need to be monitored. Equipped with a long-life VUV hollow cathode lamp (10.6 eV), the Portable PID covers a large measuring range of 0 - 2,000 ppm (ISOBUTEN equivalent).
The Portable PID meets all the requirements of a modern, low-maintenance and user-friendly photoionization measuring system.

Product Specification

Extended measuring range

A new sensor unit allows an extended measuring range of up to 2 000 ppm (isobutene) with high resolution even at low concentrations.

Easy user interface

The high-contrast, graphical 3.5-inch colour TFT display with intuitive user guidance, clear text instructions and step-by-step configuration supports the ease of use even in bad lighting.

High performance PID lamp

The ionization source is a high stable hollow cathode lamp with an energy of 10.6 eV. With its ceramic discharge channel, the stability is improved and a longer service life of up to 15 000 hours and more will achieved.

Acoustic and visual warning functions

The Portable PID has an acoustic alarm and two ultrabright LEDs that warn when adjustable concentration values are exceeded.

Temperature / humidity compensation

The integrated humidity / temperature sensor measures in addition to the sensor signal the physical environment data and compensates their influence on the measuring result.

Large data memory

The data memory permits storage of more than 60 000 data records. Additionally, a separate storage is available for manually saved measuring data. A free PC software enables evaluation and logging of the saved data.

Response factors

Response factors for more than 250 gases are stored in the device. Additionally, the user can expand them by up to 20 customer-specific response factors.

Diverse charging options

The Portable PID is equipped with a standard USB connection and can be charged with any common USB wall adapter or car charger.

Easy calibration

The Portable PID is calibrated with 100 ppm Isobuten at delivery. Calibration can be adjusted or repeated when required.

Stationary detector for VOCs

The Stationary Photoionisation Detector SPID3 is a continuously measuring detector for volatile organic compounds (VOCs) with an ionisation potential < 10.6 eV. The use of new technologies for the light source and the sensor enables a high stability of the measurement and longer maintenance intervals. Automatic purging and automatic calibration are controlled via an integrated activated carbon filter and the sampling circuit. The device is designed for operation in potentially explosive atmospheres.
