Appendix D: PID Sensors
Overview
The PID (photo ionization detector) sensors are used for applications where high
sensitivity is needed to monitor ppm levels of VOCs (volatile organic compounds). This
appendix describes the EAGLE 2’s PID sensors and includes instructions to use an
EAGLE 2 that has a PID sensor installed. It also includes instructions to maintain and
replace a PID sensor.
Table 13: EAGLE 2 PID Sensor Specifications
Description
Two types of PID sensors can be used with the EAGLE 2, a low range (high sensitivity)
sensor and a high range (low sensitivity) sensor (see Table 13 for specifications). The PID
sensor is installed in a single sensor flow chamber which is located in the area next to the
standard 4-sensor flow chamber. This area can accommodate up to three single sensor
flow chambers. Figure 27 below illustrates a typical PID sensor location in front of the
pump. The PID flow chamber may also be installed in one of the other two sensor
chamber locations depending on the particular version of the EAGLE 2. Some PID
instrument configurations do not include the 4-sensor flow chamber.
