·Features
1. the temperature control accuracy can be precise to 0.01 oC by the new integrated digital electronic circuit with high control precision and reliable performance.
 
2. It has the functions of self-diagnosis for boot, stopwatch (for determining the flow), timer operation, storage protection for power off, keyboard locking, anti-interference, network data communication and remote control.
 
3. It can gets lower limit of detection by unique injector system design.
 
4. You can choose automatic/manual gas six-way valve injector, headspace injector, thermal desorption injector, cracking furnace injector, methane conversion furnace and auto-injector.
 
5. the program heating and the furnace temperature precision can be controlled stable and fast.
 
6. Optional detectors are FID, TCD, ECD, FPD, NPD and PDHID. All detectors can control the temperature individually. FID is easy to assemble and disassemble for cleaning or changing the nozzle. TCD stable time is ≤20min.
