Description
3 Channel System: Control Unit with Temperature Measurement, incl. Software Software
The Gelnorm®– Geltimer PTC-3 evaluates all factors which influence the gel time of reaction resins such as type and quantity of hardener, accelerator, inhibitor, filler, pigments, as well as temperature and moisture. The instrument is extremely easy to operate and normally needs no maintenance.
The principle of measurement of Gelnorm®– Geltimer is simple: A stamper made of aluminium or stainless steel performs an up-down cycle in a test tube filled with resin. When the point of gelation is reached, the test tube is pulled up by the stamper. This stops the clock which was started at the beginning of the experiment and the gel time can be read of.
With the probe temperature system the exothermic reaction can be measured. With the optional temperature controller PTT-3 and electric heating Block GT the sample mixture can be heated up and controlled.
