HI 150 is an indicator with a relay Output and
built-in LED Alarm Signal for the monitoring of
temperature.
Constructed in a compact casing and with a molded
eye, HI 150 can be installed on the QC bench or
wherever necessary to control the ambient tem-
perature of food chain, from the storage room to
the point of delivery.
The housing has been completely sealed against

vapors and humidity.
The measurement range is from -20 to 60ºC  with
an excellent ±0.5ºC  accuracy. The stainless steel
encapsulated sensor is positioned right on the

outer body of this thermometer to provide a rapid
response.
In order to ensure that temperature control is
never interrupted, HI 150 runs permanently on a
12 VDC power supply. Temperature is constantly
displayed on a large LCD so that the operator  can

check it at any time.
HI 150 also offers  a unique alarm control. Any
value from 0  to 50.0ºC (HI 150-00) or  -20 to
20ºC (HI 150-10) can be adjusted as the setpoint
through a trimmer located on the back of the
meter. Should the temperature vary from this user-
selectable setpoint, the red LED blinks and the

relay is activated to warn of an abnormality or
switch on a  system. The built-in LED is well visible
from a distance.
This alarm relay is a cost-saving feature with a
tremendous potential that can help you in auto-
mating your  temperature control. It can also be
used as a forewarning that the refrigeration  or air

conditioning  unit is malfunctioning, or that a door
has been left open, or point to any other mishaps,
common in a busy workplace.
HI 150 is a convenient and  inexpensive  way to
ensure  that temperature  never varies too much
from acceptable levels. It frees workers  from hav-
ing to manually check the temperature and
immediately signals if and when an abnormality

arises.
