Testing and Validation
Technology and design developed by TE
Connectivity have been tested with the sensor
package exposed to saltwater, chlorine water,
and diiodomethane (methylene iodide, MI) gas.
Diiodomethane exposure has been shown as the
harshest test. The figures below illustrate the drift
in signal output of the sensing element concerning
the diiodomethane and chlorine water exposure.
The drifts are considered very limited. Additionally,
the drift in offset can mainly be explained through
the presence of the humid environment rather than
the diiodomethane in it. Another accelerated life
test, at 85°C and in 85 percent relative humidity
(RH), showed the same drifts in offset and span, as
plotted alongside the diiodomethane results.

CHLORINE TESTING (FIGURE 7)
Test Conditions and Procedure:
• Samples fully submerged in a chlorine solution
at 60°C for 6 hours
• Dried in a temperature/humidity chamber at
60°C and 60% RH for 18 hours
• Test and record data
• Repeat steps 1–3 until 40 cycles are completed
• Repeat steps 1–4 at increasing levels of chlorine
concentration (from 20ppm to 100ppm)
• Samples were compared with standard
packaged sensors (not enhanced for harsh
media).
