thermal ageing test chambers

lr series thermal ageing test chambers
　

feature

l direct display of power consumption, adjustable ventilation amount.

l microcomputer pid temperature controller with digital display, setting is simple, operation is convenient.

l independent overtemperature protection controller improves safety and reliability of products.

l forced ventilation circulation, incoming and outgoing

l ventilation devices are set to guarantee the ventilation.

rotary plate driven by motor can be se-lected to heat samples in rotating way to study the change of rubber and plastic samples during fixed time.

application

l used for thermal ageing test of rubber and plastics and electrical insulation material.

l it can also be used for drying, baking and heat treatment of ordinary samples

l used in iec540 << insulation of cable and flexible wire and test method of sheath (elastic and thermoplastics)>> test.

standards implemented and met

thermal ageing in air test chamber: jb/t7444-1994
