Printing ink viscosity problems
eliminated
Thanks to the Viscolite 700 portable viscometer from Hydramotion, ink viscosity problems are a thing of the past for a world-leading manufacturer of plastic identification tags
Measuring viscosity with the Viscolite is simplicity itself: the solid-rod probe is simply dipped into the ink and the measured viscosity is immediately displayed on the read-out unit When the plastic tag production engineers saw the Viscolite being used by the technicians who installed the printers, they were impressed by its convenience and ease of use

Shipping channel navigable depth and mud metering
The Hydramotion MudBug is a safe, easy-to-use system for determining the navigable depth of a shipping channel by making reliable real-time measurements of the density of the silt or fluid mud
"It was a simple decision to buy our own," commented one.
The identification tags are printed with MEK solvent-based ink using a patented laser marking technology.
Operators check the printing machines regularly and make the necessary adjustments to keep the viscosity set between 3.4 and 3.8 cP, adding ink or make-up fluid (thinning agent) as required.
Controlling the viscosity of the ink is essential, because if the viscosity is not correct the ink drop cannot be charged properly and the printing machine will misprint.
With the company's high-volume production this can be costly.
The fully-portable Viscolite is factory-calibrated to traceable international standards, making it ready for use straight out of the box without requiring calibration or set-up by the user.
An integrated temperature sensor enables measurements to be taken ad hoc and corrected to a reference temperature, enabling operators to check ink viscosity instantly at the working temperature of the machine (29C).
The benefits to the company have been immediate.
"We haven't had any down time due to viscosity issues and we can now perform our own preventative maintenance and ink head calibrations," said the engineer: "The performance of the Viscolite 700 has been great and the service from the people at Hydramotion has been outstanding.
All our previous viscosity problems have been eliminated". Request a free brochure from Hydramotion ...
