3. Installation
3.1 InstallationLocation
The OX400 is a measuring instrument intended to be installed indoors. Install and operate it in a
location that meets the following conditions in order to ensure the best performance.
(1) Location where there is no corrosive gas.
(2) Indoor location where there is no mechanical vibration.
(3)Locationthatisnotexposedtodirectsunlightandradiantheat.
(4) Location that is free of dust and dirt particles.
(5) Location with a room temperature of 0 to 40°C and no condensation.

• The OX400 is a measuring instrument intended to be used indoors. Do not install it in a location
thatisexposedtodirectsunlight,wind,andrain.
• DonotusetheOX400inalocationthatmaybesubjecttovibrationsandimpact.Doingsomay
cause destruction and damage to the internal sensor.
• Do not apply a pressure of 30 kPaG or more to the gas inlet. Doing so may cause destruction of
the suction pump and damage to the sensor. Be sure to reduce the sample gas pressure to the
atmospheric pressure level before introducing it.
• Besuretousemetalpipingforthegaspiping;particularlywhenhandlingoxygenconcentration
in 1 vol % or less. Use of piping materials such as polyethylene, vinyl, rubber, and plastic may
causesignicanterrorsinmeasurementsbecauseoftheirlargeoxygentransmissionand
absorption rates.
• The presence of corrosive gas components (H

, HF, and the like) or potentially
toxicelements(Si,Sn,Cd,Te,As,P,andthelike)inthesamplegasmaycausedeteriorationof
thesensor.Besuretoremovethemwithanactivatedcarbonlterorthelikeinthepreviousstep
of the OX400 before introducing the gas.
• The presence of combustible gas in the sample gas may cause errors in measurements

lterorthelikeinthepreviousstepofintroducingthesamplegasintotheOX400.
• Make sure the temperature of the sample gas is 50°C or less.
• Be careful because the presence of water droplets in the sample gas may cause damage to the
sensor.
• Keepthesupplygasowrateandpressureasconstantaspossiblewhileintroducingthegas.
• Keep the sample gas outlet open to the atmosphere during operation. If a gas line must be used
for discharge gas, use a gas line with a connector that has the largest possible diameter in order
to prevent back pressure.
