2.3 Response Test

Prior to use, the unit should first be tested for proper response. With the detector operating, the unit should be exposed to a sample of the target gas.The display should show an increasing concentration. If not, do not use it for field measurements.

2.4 Sample Inlet Port

The Honeywell EC-P2 is provided with a quick disconnect flexible extension wand. It will work with or without the wand. When using the extension wand, the internal walls must be kept dry. Water on the walls of the tubing can potentially absorb the target gas. To dry, allow the unit to pump dry, ambient air for 15 minutes.

2.5 Response/Recovery Time

Under normal conditions, the instrument will reach 90% of final value within two minutes. This is dependent on concentration and temperature.

Recovery time for the sensor depends on duration and concentration of exposure. Short exposures of concentrations at the lower end of the target gas range result in rapid recovery. Long exposures to levels above the middle of the target gas range or short exposures to levels exceeding the target gas range can extend recovery times to hours. Repeated exposures above the target gas range will reduce cell life and should be avoided.
