YOUR LITHO-KIT™ GUIDE
CONDUCTIVITY AND pH: HOW THEY CAN HELP YOU The Myron L instrument which is the "heart" of your kit is either a conductivity instrument or a conductivity/pH instrument. Both are industrial-quality instruments for professionals. Reliable even in demanding conditions, they feature electrodes mounted inside a cell cup for maximum protection. Details of specifications and operation can be found in the instruction manual in each kit. Conductivity is the ability of a solution to pass an electrical current.
Because contaminants in water are often ionized, conductivity has long been recognized as a good overall indicator of water quality. Portable conductivity instruments and/or in-line conductivity monitor/ controllers are normally included in industrial reverse osmosis and deionization water treatment systems. If the system in your plant did not include a Myron L portable instrument, the instrument in your Litho-Kit™ can be used to check: 1. System Efficiency 2.
. As the press run continues, observe the changes in pH and conductivity. When printing problems such as plugging or scumming begin, the dampening solution is probably contaminated. Record your findings in the press log book and remix a fresh batch of solution. 6. If alcohol is used in your fountain solution, it should be added after the solution has been mixed to the desired conductivity range. Alcohol has no conductivity, and it dilutes the solution conductivity value.
