Portable PhotoIonization Detector for VOCs
|
The Portable Photoionization Detector PPID3 is a 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. |
Product Specification
Extended measuring rangeNewA new sensor unit allows three staggered measuring ranges up to 2 000 ppm (isobutene) with high resolution at low concentrations. |
Easy user interfaceA graphic display with intuitive user guidance, clear text instructions and step-by-step configuration support the ease of use. |
High performance PID lampThe ionisation source is a hollow cathode lamp with an energy of 10.6 eV. The Ceramic Discharge Channel ensures high stability and a longer lifetime of up to 15 000 hours and more. |
Acoustic and visual warning functionsThe Portable PID has an acoustic alarm and two ultrabright LEDs that warn when adjustable concentration values are exceeded. |
Simple calibrationOnly one calibration gas is required for the simple menu driven two-point calibration. |
Diverse charging optionsThe Portable PID is equipped with a standard USB-C connection and can be charged with any common USB-C wall adapter or car charger and has the option for wireless charging. |
Temperature / humidity compensationThe integrated humidity / temperature sensor measures the physical environment data in addition to the sensor signal and compensates their influence on the measuring result. |
