Product Description

Product Description
CIT21-30S explosive limit tester in line with ASTM E681-04 standards, applicable to test the upper and lower limit concentration of combustion measurement of flammable vapor and air mixture formation of chemical substances in testing temperature and constant pressure, it can be used of inert gases as diluents in testing (but the oxidizing of substances should not strong than air). During the test, the sample to be tested is first added, heating or cooling the container round to the set temperature, stirring to mix evenly measured gas, high pressure discharge ignition, observe if the test gas explosion combustion through video monitor, if not combustion then adjust the concentration of the measured gas to detect the limit of measured gas.

Product Features

• Embedded processor, Windows CE operating system;
• 8-inch LCD touch screen which can display the test status in real time;
• Optional 5L, 12L circular glass test container
• Fitted up with an explosion pressure relief devices (door and spring-loaded pressure relief devices);
• Equipped with heating and cooling equipment, air circulating heating or cooling.
• High-precision humidity measurement module can measure the humidity inside the test vessel;
• Used pressure & humidity sensor, thermocouples combination to test sample state, it can also automatically monitor and record the test environment temperature, humidity and atmospheric pressure;
• with a high-precision pressure sensor, precise control of the ratio of the partial pressure of the gas concentration;
• magnetic stirring, remote boot control automatic ignition control, ignition timing precision;
• The internal gas extraction, automatic sample container and cleaning the combustion products;
• Configure bottle brush, with water mixed with sand + detergent wash bottle wall adhesion substance;
• The double glass observation window protective door and back door has anti-fog of relief, safe, reliable, easy to observe;
• double interlock protection, when the door is not closed or the temperature does not reach the target temperature, ignition operation is invalid;
• configure video surveillance system to record the testing process, after the end of the trial by playing back, observe the judgment final result;
• fully automated test process, support function parameter setting, data storage and view the reports.
