  Features of T-Long TZ-1400S heat treatment furnace with RS485 port :


1.Temperature controller:

PID method is used to adjust up cool;
Can be set up to 30 litres of cooling process, with overheating and broken accidentally protection
For the accuracy of temperature control: DHS + / - 1 C
The furnace body equipped with RS485 communication interface
Can choose and buy one PC control module, can lower the temperature will rise and the temperature curve is imported into the computer, in order to achieve the remote control
At the same time the company can also act as purchasing agency for the customer computer, install the software in the computer, to provide customers with convenient, save time.

2.Control circuit:


Adopts digital display power regulator module, more powerful function. Heating and cooling are more stable and reliable. 


50/60HZ available:


3.Safe energy:


The furnace chamber is made of high strength,low density ceramic fiber insulation which can safe more energy.



4.Temperature uniformity:


According to the character of furnace liner and heating elements, we calculate the power and install heating

 elements reasonably. The temperature uniformity is ±5℃
