Litho-Kits
are available for the Ultrameter
II
6P (ULK),
512M5 ( CLK) and
M6/PH DS/pDS Meters (PLK).
ON-THE-SPOT
TESTING
The increasing
use of alcohol-free and alcohol-reduced fountain solutions
places greater importance on monitoring conductivity, pH and
temperature. The easy to-use Litho-Kit along with your Myron
L instrument allows the ability to take these important
tests. Litho-Kits are self-contained, quality control tools
for fountain solutions when purchased with the Ultrameter
II
6P or M6/pH Meter.

CONDUCTIVITY and
pH
Many of today's
fountain solutions are pH buffered, so only small changes in
pH are seen, even with large changes in solution strength.
Testing solution conductivity is an accurate way to measure
concentration. By using field-proven Myron L instruments,
the most precise etch/water mix can be quickly identified.
On-the-spot measurements will allow further fine tuning
during press runs.
Although
conductivity measurement is critical, controlling pH is also
imperative. The pH of fountain solutions can affect
sensitivity, plate-life, ink-drying, etc. Use of the Myron L
instrument to maintain
|
optimum pH and
conductivity will result in consistent, high-quality
printing.
TEMPERATURE
Because
alcohol-free solutions are less viscous, it is highly
recommended to regularly check the temperature during press
runs. The Litho-Kit includes an 20 mm/8 in. long-stem
thermometer to check the temperature of the solution in the
fountain pan
the most accurate place to test.
AS SIMPLE TO
USE AS 1-2-3
Step 1:
Draw sample from pan
with syringe.
Step 2:
Fill cell cup with syringe
contents.
Step 3:
Push buttons to read
conductivity and pH. |
