It is a simplified electronic device. Two separate working stages. The first program was developed especially for fast castings and has the features of temperature rise, stabilization time control and audible warning at the end of the cycle (repeat function). The second program is best suited for conventional castings and can offer up to three temperature thresholds with increased gradients and retention times that can be pre-adjusted to specific requirements. Software security for up to 100 hours delayed startup and shutdown. Highest reading accuracy and temperature control at each operating stage. Integral alumina heating chamber providing high-level primary and secondary insulation.
