KOWA analysis items
!
Analysis of metal wear particles
This uses an ICP (Inductively Coupled Plasma) analyzer to
measure the density of metal wear particles in the oil.
!
Measurement of particle quantity
This uses a particle quantifier index measurement machine
to measure the quantity of iron particles of 5
µ
or more,
enabling early detection of failures.
!
Others
Measurements are made of items such as the ratio of water
in the oil, density of the antifreeze coolant, ratio of fuel in the
oil, and dynamic viscosity, enabling a highly precise diagno-
sis of the machine's health.
Oil sampling
!
Sampling interval
250 hours: Engine
500 hours: Other components
!
Precautions when sampling
"
Make sure that the oil is well mixed before sampling.
