Infrared thermometers allow temperatures to be measured without physical contact with the

subject – just point the instrument and read off the temperature. They are ideal where access to

the subject is difficult or dangerous or where quick checks are required to identify potential problems.

KM848

Similar specification

and features to the

KM 846 plus:

• Extended range -32°C

to +760°C

KM842

Robust design for

tougher applications

• -32°C to +400°C range

• Displays current and

maximum temperatures

• Data hold

• Switchable backlit LCD

• Scales °C, °F

KM814

Lightweight, compact

and pocket sized for

quick checks

• -18°C to +260°C range

• Backlit LCD

• Hold function

• Scales °C, °F

Emissivity: 0.95 emissivity is a good

general compromise for non-metallic

target materials. Adjustable instruments

allow more accurate matching

to the emissivity of the material.

Distance to spot size ratio:

The smaller the distance to spot size

ratio, the better for close-up work.

The lar

ger ratio is more effective over

longer distances.

Infrared Thermometers

For safe, non-contact surface temperature measurement.

KM846

Similar to KM842 but allows the connection of

a contact probe for more accurate temperature

checks when a problem is identified,

plus additional features:

• Extended range –32°C to +600°C

• 12 point data logging capability

• Max, min, dif

ferential and average

temperature functions

• Display recall

• Audible and visible high/low

alarm indication
