Similar to 36235 series but these furnaces feature three stage, PID control with ten programs (programs 1-9 are general, three-stage programs; program 10 is a continuous hold at a set temperature). The program linking feature allows you to run two, three-stage programs sequentially. Use the seven-day delay to program the completion day and time. Temperature range is 50 to 1100°C with control accuracy of ±5°C. Temperature uniformity is ±8°C. Time range is 00:00 to 99:59 hours.
