occur by accidentally touching only one key. The actual temperature is permanently displayed by 14mm high
numerals after the keys have been released. An adjustable safety device against overheating prevents the hotplate
and the substance to be heated, from dangerously high temperatures. A removable Plexiglass cover prevents any
un authorised adjustments. All models have an electronic output control that allows the heating output to be adjusted
between 10..100%, this pre-vents the hotplate exceeding the preset temperature and/or avoids any after-heating. The
temperature of all hotplates is measured with a built-in, quick-reaction sensor (PT 100).All models are equipped with a
3-pole diode output bushing(extra-low voltage), to permit the connection of
one of the following appliances:
1. Contact Thermometer – to measure the temperature directly from the heated material and to regulate.
2. Time switch – in order to heat or cool the apparatus at preset intervals. Model PZ-6116 (long shape) is equipped with
5 screw-in sockets for support rods, at intervals of 125 mm.
Special Feature:
Due to the asymmetrical, quick-reaction special heating and thermal sensors as well as output
adaptation to the thermal requirements, very precise temperatures with a good uniform heat are obtainable over the
whole heating surface.
300°C Precision
PHP-Series, Precision Hot Plates non-stop operation
The heating surfaces of the precision hot plates
are composed of an efficient heat conducting Aluminium
alloy,and have a smooth anodized finish for easy
maintenance. The electrical long-term heating ensures that
the temperature remains constant, even on the corners
and edges. The microprocessor controlled digital
regulator allows the operating temperature to be preset in
0.1°C stages up to 99,9°C and in 1.0°C stages for
temperatures over 100°C.The preset temperature
remains programmed, even when the equipment has been
switched off. Presetting is only possible by using two fingers;
this is to prevent anyunintentional alterations that could
