1 : When mount in 17 mm hole in panel, panel thickness can be up to 4 mm. 2 : Within 5 cm of sensor tip, can reach 250°C.
3 : Specify Option code /S, or Model K9424DB, for metal nipple.

Measurement cautions * 1 : Sensor should not be exposed to silicone vapor, silicon gas.
2
* 2 : Corrosive or flammable gases, halogens, Freon, or organic solvents may adversely affect sensor.
Box is to be filled with inert gas
If organic solvents in box, use sampling unit
Use sampling unit, remove alcohol / flux from furnace
Use sampling unit if organic solvents present
High temperatures, so use metal nipple K9424DB
Use OX102 with Hi/Lo Alarms, or OX100-3 (Lo)
Use sampling unit if disinfectant is alcohol-based

Usage cautions
Example: N2 reflow furnace
Temperature : 120-130°C
Gas flow : 1m/sec.
Environment : Alcohol / Rosin / Flux,
Oxygen 100 ppm
Compared with oxygen
meter it replaced,
Response was faster, so changes were
quickly detected
Easy maintenance for Sampling unit
(easy replacement of filter, activated carbon)

Example: Measuring oxygen
concentration in welding furnace
Temperature : Room temperature,
atmospheric pressure
Gas flow : 30 Nl/min. (N
Environment : Oxygen about 500 ppm in N
Low oxygen concentration in furnace:
safety precautions required
OX100 can detect atmospheric air leakage into
furnace which causes oxygen to rise to 200 ppm,
so can help with welding quality assurance.
