Taking Measurements

To take a temperature measurement using your INF195C, 

you simply point the aperture at an object (with or without 

using the laser sighting) and pull the trigger. The object’s  

temperature will show up on the display and update at a rate 

of approximately 2 times per second.

There will be a delay of approximately one-second between 

the time you initially pull the trigger and the time the display 

comes on. The 60-second auto-hold initiates at the moment 

you release the trigger. 

NOTE:

 

This thermometer will automatically shut off if left 

idle for more than 60 seconds, unless in PRB mode. When in 

PRB mode, instrument will shut off if left idle for more than 

12 minutes.

Follow these general guidelines to ensure you get the most 

accurate readings possible:

• Be sure the measured object fills the “spot” seen by 

the 

laser targeting. The distance to spot ratio for the 

INF195C is 12:1.

This shows the one-foot spot fitting within the one-foot tar-

get area. At this distance, and anything closer, the  

target’s temperature will be accurately measured. 

NOTE:

 

If the two-foot diameter spot includes unwanted 

objects in the background that are not part of the  

one-foot square target: the temperature of the  

background objects will be figured in with the target’s tem-

perature and throw off your measurement.

• When comparing temperatures of similar objects 

that are far away, take your measurements at the 

same distance and angle to the target each time. 

• When looking for abnormally hot or cold targets it 

may be acceptable to include background objects 

so long as the temperatures in the background 

and your methods are consistent.

• Consider the emissivity of the objects you

are measuring.

• Prepare a surface for measurement. Infrared 

thermometers measure only the outer surface of

an object. If emissivity is affecting the 

measurement, or you have difficulty putting the 

object in the sensors line-of-site, you may need to 

  prepare a surface that’s easy for the infrared  

thermometer to read. A piece of masking tape is a  

good target and it will rapidly take on the 

temperature of the object it is attached to. 

• Be aware that you cannot measure the 

temperature of air between the Infrared 

thermometer and an object. Air vents (registers) 

are quick to take on the temperature of outlet air. 

However, you must aim directly at the vent if you 

are measuring outlet air temperature.

• Keep your infrared thermometer away  from 

strong electrical fields. When working near a 

strong electrical field, like that under the hood of 

your car, watch for unusual readings or an “over

load” indication. Often, you can move the 

thermometer just a few inches to escape the 

influence of the interference.

• Keep your INF195C within its use and storage

temperature range. Excessive heat or cold will 

adversely affect the accuracy of your readings. 

When the trigger is pulled, the target’s 

temperature will be displayed in a near real-time 

mode (less than 1/2 second between 

  measurements). The temperature will remain  

on the display for seven seconds after the trigger  

 is released.

Emissivity

  Not all surfaces emit infrared energy at the same  

level.  A shiny surface will emit much less infrared  

energy at a given temperature when compared to  

a flat black surface. The INF195C has three preset  

emissivity levels used to compensate for variances  

in your target.

  High (0.95) will work for most common surfaces  

and is set as default for many infrared 

  thermometers.  Medium (070) is best for oxidized  

copper or rusty iron.  Use Low (0.30) for surfaces  

that emit less energy  such as aluminum or brass. 

Mode and Functions

Press the “

MODE

” push-button will scroll through the 

following options:

:  Emissivity data. (The default emissivity  

is 0.95)

:  Press the “

MODE

” push-button, then press  

“     “ or “      “ push-buttons to set the  

  emissivity, then press the “MODE” push- 

 

  button again to confirm it. The emissivity  

can be changed between 0.30, 0.70 and  

0.95.

:  Press the “

MODE

” push-button for the  

maximum (

MAX

), minimum (

MIN

), differential  

between MAX and MIN (

DIF

) and average  

 (

AVG

) modes. During the measurement,  

the special modes reading will be displayed  

at the bottom of the display near the  

mode icon.

:  Press the “     “ or “      “ push-buttons to  

change the “High Alarm” (

HAL

) or  

“Lo Alarm” (

LAL

), then press the trigger to  

confirm it. For example: when the reading  

81˚F < LAL 81.1˚F, the low “Lo Alarm” icon  

will flash and you will hear a beep sound.

:  Connect the thermocouple to the  

thermocouple socket and apply the probes  

to the target being measured. The  

thermometer will display the temperature  

automatically without pressing any buttons.  

To see the minimum or maximum data  

during the probe measurement, please hold  

down the “     “ or “      “ push-buttons.

INSTRUCTION MANUAL

Introduction

The INF195C is perfect for frequent use in advanced or  
specialty application environments, where wide tem-
perature ranges and superior optics are essential for 
use on targets at greater distances. This full-featured 
IR Thermometer is the most comprehensive and 
best-valued Infrared Thermometer on the market.

The INF195C’s increased features offer advanced trend  
analysis for professionals that require a greater quality 
of infrared optics, extended measurement and the ver-
satility of a K-Type surface or contact probe and three 
level emissivity to simplify operation.

Features include:

  • –76°~ 1022°F (-60˚~ 550˚C)

• Circular laser targeting
• 12:1 Distance to Spot Ratio
• MIN/MAX/Differential, Average
• 3 emissivity levels: (0.30, 0.70, 0.95)
• Hi/low Alarm (User adjustable)

 • K-Type thermocouple input
 • Carrying Case

Safety Notes

Before using this meter, read all safety information 
carefully. In this manual the word “

WARNING

” is used to 

indicate conditions or actions that may pose physical haz-
ards to the user. The word “

CAUTION

” is used to indicate 

conditions or actions that may damage this instrument.

NOTE

The INF195C is not recommended for use on 

shiny surfaces such as chrome, mirrors or  

polished metals.

          

WARNING!

To avoid thermal shock, the instrument should be 
stored at room temperature between 32˚ to 122˚F (0˚ 
to +50˚C).

          

WARNING!

DO NOT look directly into the laser beam. Permanent 
eye damage may result.
