Laboratory hotplate PL-4428

Design features

The heating surface made of duralumin and the PID controller provide high accuracy and uniformity of the temperature of the plate surface heating.

The body of the plate is made of corrosion-resistant steel.

The design of the plate protects the body, electronic components and controls from spilling liquids onto the heating surface.

Operating features

Two modes of operation of the plate allow maintaining the temperature of the heating surface for a specified time or without time limit. The display shows both current and st heating parameters.

During the operation of the plate the user can change the time and/or heating temperature.

When the plate is turned off the settings of the last operating mode are saved.

For safety purposes, the plate is equipped with:

- hot surface indicator able to work during the mains switch is off;

- the device of the thermal protection protecting a plate from an overheat.

Specifications

Operating temperature range of the heating surface: from 40 to 400 ^��.
