accidentally touching only one key. The actual temperature is permanently displayed by 14mm high numerals after
the keys have been released.
An adjustable self-protection against overheating prevents the hotplate and the substance to be heated from being
subjected to dangerously high temperatures.
This protective device is activated when the START button has been depressed. A removable Plexiglass cover prevents
any unauthorized adjustments.
All models are equipped with an electronic output regulator that allows the heating output to be adjusted between
10 to 100%, this prevents the hotplate exceeding the predetermined temperature and/or to avoid any after-heating
effect. The temperature of all precision hotplates is measured with an integrated, 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 PHP-6116F (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.

PHP-3535F/6116F, Precision Hot Plates for non-stop
operation
The heating surfaces of the hot plates are composed of
a good heat conducting Aluminium alloy, and have a
smooth anodized finish for easy maintenance. The
electrical long-term heating ensures that the temperature
remains uniform, 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 any unintentional alterations that could occur by
