Description

This advanced infrared hot plate and stirrer from Wiggens features an easy-to-clean anti-corrosive top plate made of ceramic glass and a bright, clear TFT screen that displays temperature, stirring speed, time and safety temperature. The WH280-NH can rotate in a clockwise or counterclockwise rotation and features self-optimising Intelligent Cascade Control for optimal temperature stability.

The WH280-NH has a sealed outer shell and isolated critical parts to enhance longevity even in harsh operating conditions and a drainage system above the control board to prevent liquids accessing the instrument's interior.

The WH280-NH has a connection for a PT100 temperature sensor (included with the instrument purchase) to allow for external temperature control. A high temperature indicator enhances operator safety during operation and a sensor in medium alarm notifies the end-user of sensor failure during heating.
