DR-3030

Thermal conductivity is an important index used to evaluate the thermal conductivity and insulation performance of heat-resistant materials. The heat flow meter DR-3030 is used to determine the thermal conductivity of various homogeneous plate materials such as plastics, rubber, glass, fiberboard, styrene board, extruded board, foamed concrete, hollow glass, wood board, and granular materials, bulk materials, soft materials, etc. under different temperature conditions.

Features
· It adopts OMRON programmable logic controller CPU unit and its matching temperature expansion module, which has strong anti-interference ability and high stability.
· Schneider's new solid-state contactless switch device is used for isolation control, which has high reliability, low noise and fast switching speed.
· It adopts computer standard RS-232 serial port, which is highly reliable and easy to use. PID control, through software self-tuning to adjust PID parameters, ensures temperature control accuracy.
· Three groups of six specimens can be placed at one time to avoid deviations in thermal conductivity caused by system errors.
· The software control system includes two modes: automatic control and manual control.
