September 16, 2008 Thank you for your habitual use of our MALCOM product.

　This is an important announcement for the user of our spiral viscometer on the viscosity measurement.

　It became clear that, when using the spiral viscometer for a long time, viscosity measurement value may be affected if the viscometer is used with worn inner and outer tubes (sensor portion). This is because prolonged viscosity measurement (*1) causes the inner tube and outer tube to wear and lose their original external dimensions due to abrasion, thus making it difficult to obtain correct measurement. This phenomenon is especially remarkable when using the solder paste (*2).

　When worn inner and outer tubes are used, correct viscosity value may not be indicated even if calibration is performed using the semi-standard calibration fluid (silicon calibration fluid) supplied by us.

　As a corrective measure against this problem, we established a service system where the wear on the customer's inner and outer tubes can be checked through comparison with the standard inner and outer tubes which we prepared newly for this purpose. For ensuring accurate and correct viscosity measurement, we ask you to undergo periodical wear inspection on the inner and outer tubes. Measurement can also be affected by the deformation and scar on the inner and outer tubes. This point should also be checked.

　For further details of this service, please make inquiry to our company.

*1 The operating time when the measurement accuracy is begun to be affected is under investigation. This phenomenon is noted on devices used continuously for measurement for several years.

*2 Thixotropic specimen containing materials that can abrade stainless-steel inner and outer tubes.

Target models:

1. PCU-5*
2. PCU-200 series
3. PC-1TL(type A)

* Production of PCU-5 is discontinued, and this service may not be applied depending on conditions.
