Temperature Controllers
|
-
6 digital temperature controllers for controlling each heating zone
-
PID automatic control with 30 programmable segments for precise control of heating rate, cooling rate and dwell time.
-
Built-in overheating & broken thermocouple protection.
-
Over-temperature protection and alarm allow for operation without attendant(s).
-
+/- 1 ºC temperature accuracy.

Optional:
-
The furnace may be operated by PC by installing a control module. Please order an MTS-02 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 .

European Temperature Controllers (optional upgrade) |
-
1 heating channel
-
1 program of 8 or 24 segment
-
Alarm Relay: Form 'A' and Form ‘C’ built-in
-
Digital Communications: RS485
-

Application Notes |
-
The tube furnaces with mullite tube are designed for use under vacuum and low pressure < 0.02 Mpa
-
Never use graphite crucible and the alumina tube.
-
Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
-
The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
-
Vacuum pressures may only be safely used up to 1300°C for all mullite tube furnaces:
-
Customized long heating zone up to 1200 mm L with 700 mm uniform temperature zone ( +/- 5°C) ,1800mm mullite tube is available upon request;
|
Warranty |
-
One year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products page).
-
ATTENTION: Any damages caused by the use of corrosive and acidic gases are not under the coverage of Kejia One Year Limited Warranty.
|
Compliance |
-
CE Certified
-
NRTL (UL61010) or CSA certification is available upon request at extra cost.
