Thermal Shock Chambers 3-Box / Three Box Hot and Cold Temperature Air Impact Testing Machine
  • 1. Vertical Type 3-Box Test Chambers Structure:

    High and low temperature box circulation process automatic control, time maintain and time conversion is adjustable, Stainless steel internal chamber(AS),  Multi-form recording and equip with  multiple safety protection measures and devices, Perfect protection alarm function: When a short circuit, leakage, over temperature in chambers; Compressor overpressure, overload, oil pressure, water-break and other abnormal condition, the screen instantly displayed automatically fault reason and provides excluded methods. When found that the input voltage instability, with emergency stop device, hot and cold shock structure moving time in 10 seconds, Cold and hot shock temperature recovery time in 5 minutes, can be in line with the MTL, IEC, JIS, GJB specifications, etc.

    2. Extensible device:

    (1) Temperature Recorder;

    (2) Ln2 rapid cooling control system;

    (3) RS - 232 communication interface device can simultaneously with personal computer local area network on-line monitoring and recording.

    3. Functions

    (1) With high temperature, low temperature area and test area three parts, adopt a unique break hot structure and the well effective of heat and cold storage; With cold and hot wind road into test specimen for a cold and hot shock testing.

    Temperature range: - 20 ℃ -- 200 ℃;

    Test Chamber Size: 300 * 350 * 450 mm;

    (2) Micro-computer large LCD (320 * 240 dots) with both Chinese and English display control system;

    (3) High program memory capacity, program can be set to store 100 set, the largest circulation can be set to 9999 cycles, the maximum each time can be set to 999 hrs59mins;

    (4) With RS - 232 - c communication interface device, can be dynamic linked with computer control/editor/records and 10 groups (TIMER SINGAL RELAY ), easy to use. When performing a cold heat shock condition, can choose Zone 2 or 3 Zone function;

    (5) Have fully automatic, high precision system, any parts movements, entirely by P.L.C lock and treat;

    (6) When occurs failure, equipped with automatic line and warning signs; when  found that the unstable input voltage, with emergency stop device.

    4. Certification
