Safety Precautions
Read the following precautions carefully before using the thermometer.
Attention
▲Take care of the temperature probe lens, which is fragile.
▲Dispose used batteries with care. To protect the environment, you are recommended to send the used batteries to a
designated collection point.
▲Remove the batteries if the thermometer will not be used for more than two months.
▲Do not immerse the thermometer in water or expose it to direct sunlight.
▲Do not subject the thermometer to vibration or impact.
▲Do not take body thermometer readings within 20 minutes after you do physical exercises or get excited.
▲Do not use the thermometer for continuous temperature monitoring purposes.
▲Do not immerse the thermometer into water or other liquid. Clean and disinfect the thermometer as described in the
“Cleaning and Disinfection” chapter.
▲Do not touch the tip of the thermometer probe, on which a precise temperature sensor resides.
▲The ambient temperature must not be extremely high or low. To make sure accurate readings, keep the thermometer
under room temperature for more than 30 minutes before use.
▲Do not use the thermometer under an ambient temperature higher than 40℃(104F) or lower than 10℃(50F), which is
beyond the operating temperature range of the thermometer.

▲Risk of pollution! The user is recommended to send the overdue thermometer to local garbage disposal site or send it
back to us.
▲2 AAA batteries of 1.5V are the only replaceable accessories of the thermometer. Please do not use the batteries of
other voltages or specifications.
Warning
Warning

Body Temperature Basics
You can take a body temperature on the forehead, in the ear canal, under the armpit, in the mouth, or in the anus. The
temperature measured at different parts of the body may differ slightly.
Body Part
Normal Temperature Range
Forehead
36.1-37.5/97.0-99.5
Ear canal
35.8-38.0/96.44-100.40
Mouth
35.5-37.5/95.9-99.5
Armpit
34.7-37.3/94.46-99.14
Anus
36.6-38.0/97.88-100.40
The normal body temperature range slightly varies with age and gender.
Generally, newborns or children have higher body temperature than adults, and adults have higher body temperature than
the elderly. Women’s body temperature are appropriately 0.3℃higher than men’s.
Normal body temperature varies by the time of day and is also affected by external factors.
The body temperature of an individual is the lowest between 2:00 a.m. and 4:00 a.m. and the highest between 14:00 p.m.
and 20:00 p.m. An individual’s body temperature typically changes by less than 1℃each day.

Product Description
1)Overview
Infrared Forehead Thermometer ZY-NIT-3 measures the human body based on the infrared energy emitted by the
forehead. You can quickly get measurement results after pointing the temperature probe to the target.
2)Structure
The thermometer consists of a shell, an LCD, buttons, a beeper, an infrared temperature sensor, and a Microprocessor.
3)Operating principle
The infrared temperature sensor collects infrared energy emitted by the forehead. After being focused by a lens, the
energy is converted into a temperature reading by the thermopiles and the measurement circuit.
4)Intended use
The Infrared Forehead Thermometer ZY-NIT-3 is a non-contact infrared forehead thermometer intended to obtain the
body temperature from the forehead. It may be used by medical professionals or by consumers in a home environment.
5)Contraindications
None
Features

Description
Measuring Forehead temperature
In a power-on state, point the IR
sensor to the center of the forehead.
Move the thermometer towards the
forehead. For effective measurement,
the distance between the
thermometer and the forehead must
be 1/2” to 2” (1-5 cm). Press and
release the Measure button. The
forehead temperature will be
displayed on the screen.

The *★* symbol indicates the Forehead temperature mode. The *☆* symbol indicates the Correction temperature mode.
2)Press the Measure button to start a measurement
When taking the forehead temperature, point the IR sensor to the center of the forehead. Move the thermometer towards
the forehead, the distance between the thermometer and the forehead must be 1/2” to 2” (1-5 cm). Press and release the

Measure button. The forehead temperature will be displayed on the screen.
3)After a measurement
After each measurement, clean the thermometer with a dry soft cloth, and put the thermometer in a dry and
well-ventilated place.
The thermometer automatically powers off if it is not used in 60 seconds.
Notes:
The thermometer is suitable for an indoor environment without strong air convection between the thermometer and the
target. For example, winds from a fan, an air-conditioner, or a heater.
Do not hold the thermometer for a long time, because it is sensitive to the ambient temperature.
Make sure the sense head is free of foreign matters before use.
Make sure the forehead has no sweat and no hairs covered before measure the forehead temperature; otherwise, the
result could be incorrect.
No intense emotion or strenuous exercises before measuring.
Replacing Batteries
Slide the battery cover off along the marked direction. Insert the two AAA batteries into the compartment correctly.
If the low-battery symbol is displayed on the screen, replace the batteries.
Make sure that the batteries are installed correctly. Otherwise, the thermometer may be damaged.
Batteries of a same type should be used. Dispose the used batteries in accordance with the local environmental policies.
Cleaning and Disinfection
Cleaning
Recommended detergents:
*medical detergents;
*Home use mild detergents;
Cleaning steps:
Take the batteries out before cleaning.
