High-temperature furnace
HTO-34
High-temperature furnace HTO-34
for material testing in air and a heating zone length of 30 cm
General Features
The high-temperature furnace HTO-34 is characterized by an excellent temperature distribution, which is achieved by its 3-zone version.Each zone can be controlled independently, allowing precise temperature control, especially when using an appropriate temperature controller.
The furnace is made more energy-efficient through the use of a lightweight, thermally insulating and asbestos-free aluminum silicate wool.
The housing of the furnace is made of stainless steel, which increases the longevity of the appliance.
In addition, the furnaces are already equipped to accommodate a length change sensor(HT extensometers) and diametrical HT extensometers through the cross slots at the front and rear. This makes it easy to integrate measuring devices for monitoring material changes.

Features
- Double-walled construction – convection cooling reduces the outside wall temperature.
- The furnace stands on furnace supports so that the furnace can be fully opened.
- The MSRA regulator uses transformers to provide the required high current and reduce the voltage. Thanks to the lower voltage, the oven's lifespan is extended.
- Folding furnace. Fast and easy sample loading of samples possible.
- 2 double Cross-slots (front and rear for additional diametral extensometers)
- Durable embedded horizontal heating elements.
- Furnace bore optimized for a wide range of adapters and test fixtures without causing large heat losses.
- Lightweight and asbestos-free insulation material to minimize power consumption.
- Stainless steel housing.
- All electrical connections are made to the MSRA controller.
- Front cutout allows access to high-temperature extensometers.
- Uniform temperature gradient through 3 independent heating zones.
- Five feed-throughs for thermocouples, one on the right and one on the left, three of which are in the middle heating zone.
- Movable thermocouple arrays for temperature are available as an option.
- Adjustable stainless steel latches for easy locking of the furnace holder during the test.
- Upper and lower end plates with tie rod cutouts are manufactured to fit the test device.
- OFF safety switch when opening the furnace.
- 2 cross-slot extensometer openings:
For length change extensometers and for diametrical extensometers.
Application
- Heating zone length of 300 mm.
- Suitable for high-temperature tensile tests, compression tests, cyclic fatigue tests and fracture mechanics tests.
- For tensile specimens B from M6 to M20 (according to DIN 50125).
- Load rods for tensile specimens up to M20 available.
