<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">SATRA ozone testing technology has evolved as a result of more than 30 years of experience. State-of the-art technology and construction techniques have been combined with expertise to produce a reliable, accurate, fully automated, labour and cost saving unit which is truly environmentally safe.</span></p>

<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">An integral closed loop air-ozone system ensures that hazardous ozone gas is contained internally &ndash; eliminating the need to provide additional external venting and filtering of the spent gases.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">&nbsp;</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">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.</span></p>

<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">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.</span></p>

<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">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.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">&nbsp;</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">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.</span></p>

<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;"><strong>HTE 703</strong><br />Temperature Ranges options for Model 703: 0&deg;C to 70&deg;C.* 10&deg;C to 70&deg;C. Ambient (+ 5)&deg;C to 0&deg;C.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">*The testing of rubber at low temperatures 0&deg;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.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">Temperature control accuracy: &plusmn; 1&deg;C at 40&deg;C and &plusmn; 3&deg;C at 70&deg;C. Typical temperature and ozone recovery period following sample insertion&lt;10% of set point after 15minutes and 4% after 30minutes (cold start times will vary).</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">Electrical supply 220 - 240/1/50/60 rated at 2kVA system unaffected by variations of 10% from normal.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">&nbsp;</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;"><strong>HTE 903</strong><br />Temperature Range for 903model: 23&deg;C to 70&deg;C All ranges are automatically controlled by a solid state digital proportional controller temperature digitally displayed and simultaneously recorded on the integral chart recorder.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">Relative Humidity control for model 903: Range 50% to 80% RH over exposure chamber temperature range of 23&deg;C to 40&deg;C.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">Control &plusmn; 5% RH at constant temperature. Digital proportional controller working in conjunction with a three channel chart recorder.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">Water supply: Maximum temperature 15&deg;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&deg;C cannot be maintained a recirculation chiller system should be employed.</span></p>
<p style="text-align: justify;"><span style="font-family: times new roman,times; font-size: medium;">Electrical supply 220 - 240/1/50/60 rated at 3kVA system unaffected by variations of 10% from normal.</span></p>
