Handheld Infrared Temperature Measurement
Measure surface temperature easily from a distance. This non-contact type
temperature sensor is ideal for applications where contact may cause
contamination, the operator may be at risk due to high temperature, or when
an object is in motion.

Washable
The unit has a water- and dust-proof
structure (IP67) to allow washing with
water.
Use of antibacterial resin allows
sanitary operation.

Can we measure any objects
with an infrared thermometer?
Use cautions to measure
under the following conditions.
An infrared thermometer detects infrared to measure temperature.
Normally, objects that absorb more infrared emit more infrared.
This value is called emissivity (e).
We can find many objects with emissivity around 0.95 in our
normal surroundings, and this instrument can measure most
materials both liquid and solid.
(factory default: 0.95)
Radiation emissivity can vary from object to object and is
typically lower on objects having shiny surfaces.
This may result in indication errors on the infrared thermometer.
Measurement through wrap or glass
Measures temperature of wrap and glass.

<Options> We
for measuring surface temperature of shiny objects
At the same temperature, a shiny object has lower
emissivity and produces less infrared emissivity.

This table shows emissivity from typical measured items.
Note: Infrared emissivity amount depends on the surface
status and measured temperature. Please refer to the following
table just for a rough standard.

Do not look in the laser beam nor point it towards a person's eyes.
(Use caution against reflection when measuring a shiny object like a mirror)
Do not allow children to operate this device.
• For prevention of a fire, an explosion accident and machinery trouble, please do not use it at an atmosphere of inflammable or explosive gas, excessive dust, steam and electric conductivity
excessive dust.
• This product is a sensor for the temperature measurement. This product is a sensor for the temperature measurement. Please be not used except for the temperature measurement.
• It is not designed for use with medical equipment.
• By surface state, temperature, color and atmosphere of a measurement object, there is the case that the measurement is difficult.
