rightMORE INFORMATION

    • An integral closed loop air-ozone system ensures that hazardous ozone gas is contained internally – eliminating the need to provide additional external venting and filtering of the spent gases.
    • The heavy duty aluminum exposure chamber has an anti-corrosive interior and is complete with racking system to accept sample-mounting apparatus. A range of static and dynamic sample holders to international standards is available. Access is via a double-glazed, airtight and safety interlocked door.
    • Entry to the test area is prevented until the interior environment reverts to safe ambient levels. Exterior lighting is excluded from the test area via a roller shade, while the interior can be lit by the integral test inspection lamp.
    • Controls and digital displays are logically laid out on a control panel and reflect the simplicity of operation required to set up a test routine. Just set the ozone, temperature, relative humidity (903 only), test start/finish/purge time sequence.
    • The ozone concentration is variable from 1 to 500pphm (1 to 2000pphm option) and is automatically controlled and monitored. The set concentration and monitored concentration are digitally displayed, with the monitored concentration simultaneously recorded.

  • HTE 703
    • Temperature Ranges options for Model 703: 0°C to 70°C.* 10°C to 70°C. Ambient (+ 5)°C to 0°C.
    • *The testing of rubber at low temperatures 0°C is well documented and conclusions from experiments, undertaken using low temperature SATRA test chambers may have an important bearing on the future development of ozone test methods.
    • Temperature control accuracy: ± 1°C at 40°C and ± 3°C at 70°C. Typical temperature and ozone recovery period following sample insertion<10% of set point after 15minutes and 4% after 30minutes (cold start times will vary).
    • Electrical supply 220 - 240/1/50/60 rated at 2kVA system unaffected by variations of 10% from normal.
     
    HTE 903
    • Temperature Range for 903model: 23°C to 70°C All ranges are automatically controlled by a solid state digital proportional controller temperature digitally displayed and simultaneously recorded on the integral chart recorder.
    • Relative Humidity control for model 903: Range 50% to 80% RH over exposure chamber temperature range of 23°C to 40°C.
    • Control ± 5% RH at constant temperature. Digital proportional controller working in conjunction with a three channel chart recorder.
    • Water supply: Maximum temperature 15°C. Minimum pressure 2 bars. Maximum flow required 80 L/hour. In areas of hard water a de-calcinator should be used and where a maximum water temperature of 15°C cannot be maintained a recirculation chiller system should be employed.
    • Electrical supply 220 - 240/1/50/60 rated at 3kVA system unaffected by variations of 10% from normal.
