Features
- Highly sensitive Photo Ionization Detector
- Range 0...40 or 0...200 ppm isobutylene
- Resolution 0,01 ppm or 1 ppm isobutylene
- 2 × 4-20 mA or 0-10 V, RS485
Description
Volatile Organic Compounds transmitter E2618-PID is a member of new PluraSens® family of multifunctional measurement instruments.
The instrument utilises highly sensitive photoionization detectors (PID) with extremely low minimal detection levels. The transmitter exhibits sensitivity to compounds with ionization potential less than 10.6 eV, i.e. to most solvent vapors.
Two analog outputs and RS485 digital interface with industry standard Modbus RTU protocol can be used to connect the transmitter to safety or building automation systems.
