Utilize for firing test in any scientific fields!
Suitable for heating under vacuum/inert gas atmosphere!

Under the condition that high vacuum region is not indispensable

●Many numbers of samples needing for heat treatment with vacuum/gas
●MATRIX is built for between combination components and combination quantity.
●Along with MATRIX, samples are prepared and sequentially implementing heat
 treatment,so that respective property can be evaluated.

<< One of the biggest features of VF-5000 >>


Furnace with excellent heat efficiency
Realized high heat efficiency, speedy heating and max. 1100℃ reach, by one-unit molding embedded heater in ceramic fiber plate, which has excellent thermal insulation property.
Auto-vacuum/Gas replacing function
By achieving auto-programming control for vacuuming and gas supply, troublesome vacuum before heating, gas replacing and atmosphere during heating can be controlled.
Only vacuum auto-operation and manual operation are also achievable.
Adopts large color touch panel
Easy operation is attainable such as respective program input by adopting 7-inch color touch panel. Specific name can be defined as in inputted program. Visual confirmation is available as graph display for progressing status of process.
Data log function equipped in standard
Temperature data log at heating stage can be stored in USB memory (CSV file).
Attainable program storing (backup) and reading via PC.
Safety design
Heater current is always monitored and detect over-current and/or disconnection.
By isolated temperature monitoring element, heater current is directly shut down when abnormal high temperature occurs. Other functions are equipped, such as thermocouple disconnection, vacuum abnormality and furnace up/down part abnormality detection.
Hearth Up/Down function
As furnace hearth part can be up/down moving, it can easily handle with the object to be heated. No need to attaching/detaching flanges as in tubular furnace. Especially when firing times are increased, workability is drastically improved.
Replacing/Flow gas exchange signal Relay contact point, 4 points
At the time of gas replacing process in auto-running, contact point is ON at designated step. By using this signal, trigger signal as replacing gas exchange or ratio alteration timing can be executed.
Connecting external vacuum gauge
The unit is usually operated only with built-in vacuum sensor. When vacuum rate is measured at high accuracy, external vacuum gauge can be connected at connecting port.
(External vacuum gauge and piping are optional.)

Cautions ※Only inert gases (nitrogen, argon) are applied as replacing and flow gas. Unable to use oxidation/reduction gas, dangerous explosive/corrosive gas and conductive gas.
※Need to countermeasure of diffusion protection for powder sample heating. (ex. Power should be put on the crucible with the cover.)
