Infrared Thermometer
Model：KC-180B-1
Overview
KC-180B-1 handheld Infrared thermometer is a non-contact temperature measuring
instrument using laser and infrared technology. You could use this product to measure the surface
temperature of objects, which are not suitable for traditional contact measuring (such as moving
objects, charged objects, toxic objects and hard-to-reach objects).
The unit employs low consumption design and is capable to save the pre-set data
automatically, avoiding resetting it after restart. The product features a LCD with backlight,
holding the readings automatically and a laser pointer for accurate aiming. It has the advantages of
rapid measuring, easy and safe operation and portability. It is widely used for applications as
finding the hot spot of electric connections and bearings, measuring the temperature of high
frequency induction heated objects, monitoring food processing and storage, inspecting
temperatures of heat & refrigeration system, inspecting temperature for technics control in
metallurgy industry, inspecting temperature during laying asphalt and fire-control process, or other
circumstances in which the temperature field to be measured is not allowed to be compromised. It
is an essential measuring instrument for the metallurgical industry, the electric power plants, the
chemical industry, the rubber industry, the spinning and weaving industry, the plastic industry, the
papermaking and the food processing. The product KC-180B-1 provides a type K-thermocouple
input socket, which makes it possible to measure wider temperature range.
KC-180B-1 Infrared thermometer is a Class II laser product and in compliance with the
safety standard EN60825-1.
Safety Introductions
Fail to follow the instructions listed below may cause personal injury.
●Read and understand all instructions prior to any operation.
●Do not remove any labels from the tool.
●Do not operate the tool in the presence of flammable/explosive gases.
●Do not operate the laser tool around children or allow children to operate the laser tool, failure to
do so will injure children’s eyes.
●Do not stare into the laser beam.
●Do not project the laser beam directly into eyes of others.
●Do not set up the tool at eye level or operate the tool on or near a reflective surface, as the laser
could be projected into people’s eyes.

●Do not observe the laser beam by using optical tools such as binoculars, magnifying glasses.
●To avoid burning risk, please be advised that the readings of reflective objects may be lower than
the actual temperature.
●Warning:

Operation Steps
1. Pull the trigger to turn on the meter and hold the trigger for measuring. Be sure to hold the
trigger more than 0.5 seconds to have an accurate reading. The scan icon “ ” flashes while
scanning; After the trigger was released, the data is auto saved and the scan icon “ ”
disappears, meanwhile the hold icon “ ” appears. The product saves the latest 10 sets of
readings automatically. The product shuts off itself if not action in 30 seconds.
2. While ON status, the left down key on the panel is to exchange the Celsius/Fahrenheit units;
The right down key on the panel is to browse the latest logged 10 sets of readings.
3. While holding the trigger(scanning temperature), press the left upper key to switch on and off
3

the laser pointer, in the mean time the icon “ ” will be displayed or disappear.
4. While the product is inactive status (not scanning temperature), press the left upper key to
switch on and off the backlight, meanwhile the icon “ ” will be displayed or disappeared.
5. Short press the middle key on the panel to set the data of MAX, AVG, MIN, DIF, LAL, HAL
and E one by one, with the responding icons.
a. MAX：display the maximum temperature of readings；
b. AVG：display the average temperature of readings；
c. MIN：display the minimum temperature of readings；
d. DIF：display the max difference temperature based on the pre-set base
temperature；
e. LAL：display low temperature alarm data；
f. HAL：display high temperature alarm data；
g. E：display current emissivity
6. Press the middle key for 2s, then short press the left down key and the right down key to set
the emissivity, low and high temperature threshold. Finally hold the middle key to finish the
setting.
7. When the battery is low, the low battery icon “ ” will appear on the upper area of the
screen. The “ ” and “ ” will appear on the upper of the display if the reading is lower or
higher than the pre-set low(LAL) and high(HAL) set.
8. While inactive status, press the right upper key to switch between infrared measuring and
thermocouple measuring. When appears, then plug in the type K-thermocouple into the
socket which located on the right side of the instrument. Pull the trigger to get the reading.
Operation Introductions
●Battery Install
Open the battery lid on the back, insert one 9V battery (6F22/6LR61), then close the lid.
●Measuring Temperature
1. Point the product to target objects, hold the trigger to get the reading.
2. The distance and scanned area: the value of D:S must be considered ( as showed ), the
ratio should be no more than 12:1. In other words, if you are 12 inch(300mm) from the
target, the detector will measure the average temperature over a circle 1 inch(25mm) in
diameter. The field of view should cover the surface of measured objects. As shown in the
illustration above, the farther the distance from the target, the larger the measured area.

3. Field of view: Be sure the target area is larger than the unit’s spot. The smaller the
target area, the closer the distance between unit and target. However, if you want to have an
accurate temperature of an object, be sure that the target is twice as large as the measuring
area.
●Operation Notes
1. Leave no glass, plastic or water vapor etc. between the unit and target.
2. Keep the product away from the following places to reduce the risk of damaging the device:
A, Environment with vapor and dust;
B, EMF places（Electro-magnetic fields: such as arc welding machine, induction heaters）;
C, Static environment;
D, Heat shock (caused by abrupt temperature changes, allow 30 minutes for unit to stabilize
before use in such circumstance);
E, Stay away from high temperature objects;

●Maintenance
1. Lens protection: Abrupt temperature changes will cause vapor condensed on the
lens, please clean the lens after the vapor disappears. Blow off loose particles
using clean compressed air. Gently brush remaining debris away with a camel’s
hair brush. Carefully wipe the surface with a moist cotton swab.
2. Keep the device clean and tidy, avoid dropping or shocking and keep it away from
water. The housing could be cleaned with wet sponge.
