We service and intend to continue to service the
EPS WVTR meters produced for over 30 years, alongside our modern
Versaperm permeability instruments.
The older simpler WVTR instruments still
require regular maintenance, for example the electronics to be
calibrated. Electrolytic cells are refurbished and recoated as
The modern highly automated instruments are
designed to be as robust and reliable as their manual counterparts,
but still require regular maintenance and calibration. While as
much as possible is automated or included in the normal operating
procedures, calibration may require site servicing
Upgrades are available for many aspects of the
instruments, although it is often more economical to trade in
the older instruments and purchase a newer model.
Monitoring software for the digital WVTR
meters is also available, which can be used to replace chart recorders
