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 temperature 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 userselectable 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 automating 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 having to manually check the temperature and
immediately signals if and when an abnormality
arises.

TAKING MEASUREMENTS
• Turn the meter on by connecting the 12 VDC
power adapter to the meter and to the mains.
• A value will appear on the LCD to indicate the
temperature. Wait for a few minutes for the
display to stabilize.
ADJUSTING THE SETPOINT
With the HI 150, you can select your own setpoint
and be alerted with a visual LED alarm when an
abnormal situation arises.
• Unscrew and remove the rear panel and gasket
seal to access the MEASURE/SET switch.
• Move the switch to the left (SET Mode).
• With a small
screwdriver adjust the setpoint trimmer to display the desired value in the 0 to 50 ºC or -20
to 20ºC range (based on the model).
• Make sure the switch is moved back to the right
(MEASURE Mode).

• To utilize the relay function open the casing as
explained for setpoint calibration.
After wiring close the casing properly. The relay
wires should pass through the access hole.
• Whenever the temperature reading reaches the
setpoint ( considering the hysteresis ), the alarm
LED blinks and relay is activated.
Recommendations for Users
Before using these products, make sure that they are entirely suitable
for the environment in which they are used.
Operation of these instruments in residential areas could cause unacceptable interferences to radio and TV equipment.
The metal band at the end of the probe is sensitive to electrostatic discharges. Avoid touching this metal band at all times.
During operation, ESD wrist straps should be worn to avoid possible damage to the probe by electrostatic discharges.
Any variation introduced by the user to the supplied equipment may degrade the instrument’s EMC performance.
To avoid electrical shock, do not use these instruments when voltages at the
measurement surface exceed 24 VAC or 60 VDC.
Use plastic beakers to minimize any EMC interferences.
To avoid damages or burns, do not perform any measurement in micro-
wave ovens.
