What is a PID?
Short answer: PIDs detect VOCs. Long Answer: A photoionization detector (PID) uses an ultraviolet (UV) light source to break-down gases into positive and negative ions (ionization). During this process, molecules are excited by the UV light, which results in the temporary loss of an electron and the formation of a positively charged ion – thereby electrically charging the gas. These charged particles then produce a current that is measured by the PID and displayed on the meter in parts per million (ppm) or parts per billion (ppb).
Prepare for Your Rental Order
Here are a few questions to help prepare for your next PID rental:
-
Do you need to datalog?
-
Will you need a 10.6 eV or 11.7 eV lamp?
-
Will you need to calibrate the PID during the rental?
-
Do you need wireless capabilities?
