Chamber oven LYH-50

trialfor mechanical testselectric

Application
This oven is designed to evaluate thermal behaviour and pre/post-heating characteristics of wire and cable insulations and coated rubber specimens. Suitable for testing wire, leather, plastics, rubber, textiles and similar materials. The unit integrates precision air-exchange adjustment, digital voltmeter, ammeter, watt-hour meter and timer for measurement and control of air replacement rate. Horizontal forced-air circulation and adjustable side airflow plates ensure uniform and stable chamber temperature. Complies with UL1581, ASTM-D2436, CNS3556, CNS742, JIS7212, JISB7757, ASTM 5423 and ASTM 5374.
