Compact Tube Furnaces


	R 50/250/12 single-zoned	R 100/750/13, three-zone control with H100

Over-temperature limit controller

R 50/250/12 - R 120/1000/13

These compact tabletop tube furnaces with integrated control systems can be used universally for many processes. Equipped with a standard working tube of C 530 ceramic and two fibre plugs, these furnaces have an unbeatable price/performance ratio.

Tmax 1200 °C or 1300 °C
Housing made of sheets of textured stainless steel
Outer tube diameter of 50 to 120 mm, heated length from 250 to 1000 mm
Working tube of C 530 ceramic including two fibre plugs as standard equipment
Type S thermocouple
Solid state relays provide for lownoise operation

Additional equipment

Over-temperature limit controller with manual reset for thermal protection class 2 in accordance with EN 60519-2 as temperature limiter to protect the oven and load
Charge control with temperature measurement in the working tube and in the oven chamber behind the tube, please see page 63
Three-zoned design with HiProSystem control (heated length from 750 mm, for 1300 °C models)
