High Precision Tempreture Control Lab Drying Oven Environment Testing Chambers
Description:
Hanging on the sample shelf, the sample was heated under the preset temperature. Take out the sample and measure the line distance after the recovery under normal temperature. Then make comparison between the data before and after the test. Furthermore, the tensile strength, elongation and the residual rate can also be calculated out.
Test principle:
The in-built forced air circulation supply, from the wind wheel to the heater, through the wind road until to the test chamber, can be used to ensure the minimum energy loss and temperature uniformity. The air circulation can help alleviate the temperature loss caused by the opening and closings doors.
Feature and Function:
(1)Temperature control: PID micro-computer auto controller, PV/SV display,can set the temperature freely within the temperature range;
(2)Sensor: K type thermocouple with the output of 12V；
(3)Current control: Imported silicon controlled SSR without contact and spark, safe and effective.
(4)Timer:Digital display and automatic control
(5)Structure:A3 painted cold-rolled sheet of the outside, stainless steel of the interior box, insulation cotton with the thickened observing window to prevent from explosion
