Model：KC-180B
Overview
KC-180B Infrared thermometer is a non-contact temperature measuring instrument using
infrared technology and laser pointer. You could use this product to measure the surface
temperature, which is not suitable for traditional measuring ( such as moving objects, charged
objects, toxic objects or hard-to-reach objects).
The instrument features a low consumption design. It has a LCD with backlight, a laser
pointer for accurate aiming and capable of auto holding the readings. It has the advantages of rapid
measuring, easy operation and portability. It is widely used for applications such as finding the hot
spot of electric connection and bearing, measuring the hot and high-frequency induction heated
objects, monitoring food processing and storage, inspecting temperature for heating &
refrigeration system, inspecting temperature for technics control of metallurgy industry, inspecting
temperature during laying asphalt and fire-control work, or any other temperature measuring
without compromising the temperature field. It is a good measuring tool for the metallurgy, the
electric power plant, the chemical industry, the rubber industry, the spinning and weaving, the
plastic, the papermaking and the food processing.
KC-180B Infrared thermometer is Class II laser product and in compliance with EN60825-1.
Safety Instructions
Failure 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 with 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 glass.
●To avoid burning danger, remember that the reflected objects make the measuring temperature
lower than the real one.
●Warning

Battery Safety Instructions
●Please remove the batteries when clean the product.
●Remove the batteries before long term storage
●Please install the batteries properly as the instructions of the positive and negative charges
●Please dispose the batteries properly. High temperature will cause explosions and do not burn the
batteries. Strap insulated tape around the battery charges to avoid unsafe contacts with other
objects.Many countries have regulations regarding battery disposal.Please follow the local
regulations of battery disposing.

Operation Steps
1. Pull the trigger to start the instrument and measuring. Be sure to hold the trigger more than 0.5
seconds to have an accurate data. The scan icon flashes while measuring; After the trigger
released, the data is auto hold and the scan icon disappears. The screen shows hold. Auto shut
off if there is no action in 7 seconds.
2. Switch between Fahrenheit and Centigrade be pressing the right key on the panel. Turn on and
off the backlight using the left key.
3. Activate and deactivate the laser pointer using the middle key on the panel.
4. When the battery is low, will appear on the screen.
Operation Instructions
●Battery installation
Open the battery compartment, insert one 9V battery (6F22/6LR61), close the lid.
●Measuring temperature
1、Point the product to target objects, hold the trigger to read the data.
2、The distance and target area: the value of D:S must be considered ( as showed ), the ratio
should no more than the value of D:S. The field of view must be full of objects. As the
distance from the object increases, the spot size of measuring area becomes larger.
3

3、Field of view: Be sure the target area is larger than the unit’s spot size. The smaller the target
get, the closer the measured distance. For precise measuring, make sure the target is at least
twice as large as the spot size.
●Operation Notes
1、No glass、plastic or water vapor .etc should between the product and target object.
2、Keep the product away from the following places, which will damage the devices:
a、Environment has vapor and dust;
b、EMF places（Electro-magnetic fields: such as arc welders、induction heaters）;
c、Static environment;
d、Heat shock (by abrupt temperature changes, allow 30 minutes for unit to stabilize before
use.);
e、High temperature objects.
●Trouble shootings
Problems Causes Solutions
No vision Dead battery Check and replace battery.
Show“ ” Low battery Replace battery
Show “OL—” The target temperature lower than range. Choose target within the range
Show “OH” The target temperature higher than range. Choose target within the range
No suitable object and view field.①Choose proper field of view.①Temperature
differs much ②Wrong emissivity setting. ②choose proper emissivity value
●Maintenance
1、Cleaning the lens: Abrupt temperature changes will cause vapor, please clean 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 clean; Avoid drop and wet; The housing could be cleaned with wet sponge.
Cautions
●Don’t drop and use the tool by force.
●Don’t disassemble the tool, (avoid to cause trouble).
●Keep the tool dry and clean.
●Don’t place the tool with corrosive gas or objects.
●Avoid dust and water, which may stain the lens.
●Don’t clean the lens by any solvent.
●Don’t immerse the tool into water to avoid damage.
●In case of damage of tool by deterioration of battery.
●Remove the battery when not in use for an extended period of time.
