4Performance characteristics
Newly integrated digital electronic circuit with high control accuracy, stable and reliable performance, capable of reaching0.01Temperature control accuracy of ℃.
It has self diagnostic function upon startup, stopwatch function (convenient for stable flow), running timer function, power-off storage protection function, keyboard locking function, anti power mutation interference function, networked data communication and remote control function.
The design of the injection system * can achieve lower detection limits.
Optional automatic/Manual gas six way injection valve injector, headspace injector, thermal analysis injector, cracking furnace injector, methane converter, automatic injector.
Program heating and precise control of furnace temperature for stable balance are faster and more efficient.
