2-Zone Thermal Shock Test Chamber

TS 2-zone series hot cold thermal shock test chamber is available in small capacity and large capacity to meet different testing requirements. The specimen automatic transferred from cold chamber to hot chamber by basket. The basket slides vertically and smoothly through rails, to make the specimen is exposed to the two chambers.

Thermal shock test chamber has upgraded to touch-screen controller with Ethernet, you are easy to operate over network.

Key Feature

  • Smooth sample elevator transfer between cold chamber to hot chambers
  • Temperature recovery time less than 15 minutes
  • Programmable color LCD touch screen controller
  • Mechanical compression refrigeration system
  • Casters, shelf, and cable port are standard
  • Lamp inside of chamber
  • Ethernet and USB (option)
  • Large viewing window
  • Adjustable and removable sample shelves
  • Safety protection system
  • CE mark, ISO17025 calibration

Refrigerating system

  • Refrigerant: environment friendly R404 refrigerant
  • Closed-type and low-noise rotor compressor
  • Refrigeration mode: machinery compression single-step refrigeration (air-cooled condenser) and machinery compression dual cascade system refrigeration
  • R404 refrigerant: environmental protection refrigerants

Control system:

  • Touch-type temperature and humidity programmable controller
  • Operating interface: LCD display
  • Temperature and humidity controller: touch-type LCD controller 
  • Setting mode: touching type
  • Running mode: setting-up running and programmed running
  • Program: 100 groups in 100 segments
  • Resolution: temperature: ± 0.1 ; humidity: ± 1%RH
  • Input: platinum thermal resistance
  • Control mode: PID control
  • Communication function: LAN network interface
  • Additional function: alarm and display function, power-off protection function, upper limit temperature alarm function, timing function (auto start and auto stop), self-diagnosis function, curve record and display function, paperless record, USB data export, tele-monitoring and so on.
  • It can execute 100 STEP X 10 PATTEM mode.
  • Each section can be grouped and executed in crossing way.
  • The execution time for each section can be set up between 0-999H plus 59min.
  • For setting up for each group, it can circulate within 1-999 in part or entirely for option.
  • In execution, it can select group circle picture or section execution picture and can know the remaining time for execution.
  • It has power-off function. After power recovery, it can complete the remained test.
  • It can select single-section control or multi-section programmable control.
  • The screen has backlight time control function and it can adjust the backlight brightness.
  • For executing single-section control, it can change the execution value at will. The memory-type multi-function control has automatic control output functions, such as heating heater and humidifying heater for electromechanical solenoid valve for different groups of refrigerating compressors and so on.
