Temperature Controller
|
• PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired,
current limiting resistor.- • 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
- • Please click here to learn why SCR is more accurate than SSC (Solid state relay).
- • Built-in over temperature alarm and protection allows for operation without an attendant.
- • +/- 1 ºC temperature accuracy.
- • RS485 Communication Port.
- • Optional:
- • The furnace may be operated by PC by installing a control module. Please order an MTS-01
control module at extra cost. - • If you order the PC control module together with the furnace, we will install and test it before
shipping. We recommend you to order a computer (laptop) from us to avoid software installation
problems. For more information please click here.

Tube Materials: | High purity Al2O3 ceramic, Purity > 99.9% |
Processing Tube |
• Premier Grade alumina tube made in the USA- • ID: 44 mm x OD: 50 mm x 1000 mm length
- • Four fibrous ceramic tube blocks are included for blocking heat radiation from inside tube
(Ceramic blocks must be fully inserted into the furnace chamber before heating). - • Quartz blocks (optional) are ideal for cleaner processing environment and higher vacuum efficiency.
  
|
Sealing Flanges
|
• One pair sealing flange with double silicone high-temperature O-ring is included.- • Two SS needle valves and one dial vacuum gauge are installed with flange for immediate use.
- • Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^-5 torr by turbo
molecular pump. Please click the picture below to see flange assembling details.
|
Fitting Ports
|
• Standard 1/4‘’ Barbed fittings with needle valves.- • For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4"
Swagelok® Tube Fitting, please click underlined to order. - • Optional: In order to increase the throughput and achieve high vacuum, you may replace the standard
barbed hose fitting with the KF25 adapter, please click the underlined to order. - • Optional: You may also consider using the parts in below to increase the vacuum efficiency
