Appendix C: ESS-03 Toxic Sensors
Overview
The ESS-03 sensors are used to monitor levels of a variety of toxic gases.
This appendix describes the GX-6000’s ESS-03 sensors. It also includes
instructions to replace an ESS-03 sensor. Table 19 below lists the available
ESS-03 sensors.
Table 19: ESS-03 Sensor Specifications
NOTE: If you are attempting to detect chlorine, be sure the hose/probe does
not have a particle filter installed. Also be sure that the hose is not
longer than 30 feet.
Description
The ESS-03 is a smart sensor that stores sensor parameters including the
target gas, detection range, alarm points, and calibration settings in its
memory. So a sensor can be calibrated at the factory and shipped as a
replacement sensor without the need to calibrate the sensor when it is
installed as long as it is installed during the sensor’s valid calibration period
which is typically 3 months. In addition, you can change an existing ESS-03
