EC150 instruments sold prior to July 2017 were sold with
scrubber bottles that contained strong oxidizing agents.
Avoid direct contact with the chemicals inside the bottles.
Also ensure your work area is well ventilated and free of any
reactive compounds, including liquid water. Store used
chemical bottles in a sealed container until disposal.
Replacing Scrubber Bottles
1.
Twist the scrubber bottle covers of the upper and lower arms counter
clockwise until they detach (they should loosen by hand).
2.
Remove the EC150 chemical bottles from inside the covers, and
replace them with new bottles (pn 32897) with the lid of the bottle
pointing toward the snouts of the analyzer (see FIGURE
Before opening the covers, have the chemical bottles ready so that
the time the internal volume of the analyzer is exposed to the
environment is minimized.
3.
Screw the covers back on the arms. Do not overtighten.
4.
Allow the sensor to equilibrate for at least 24 hours (longer if in high
humidity).
5.
After 24 hours, perform a zero-and-span procedure. If readings
continue to be suspect, the sensor may need to be recalibrated at the

below).
The chemical bottles should be disposed of according to local and federal
regulations. For more information, Safety Data Sheet (SDS) forms for the
chemicals are included in Appendix
(p. E-1)
