1. Introduction
The SKF TKTL 31 is a portable, lightweight multi- functional
instrument for safely measuring temperatures at a distance.
Simply aim and pull the trigger and the temperature is shown on
the display. Users can also measure contact temperatures using the
probe supplied.
This feature rich instrument also has the facility to store measured
values such as Maximum, Minimum, Difference, Average, High Alarm,
Low Alarm, Emissivity setting.
2. Quick start
1. Simply aim the thermometer at the measure target with Lens (8)
and press Meas. key (6) to display the surface temperature.
2. The Distance:Spot is 75:1.
The two laser points are the reference for the target spot size.
Please make sure the target area is within the field of view.
3. Features
• LCD black and white display, backlit
• Dual laser targeting
• Type-K thermocouple probe
• Adjustable emissivity
• High accuracy
• Fast response time
• DS ratio of 75:1
As the distance (D) from the object increases, the spot size (S) of the
area measured by TKTL 31 becomes larger.
The relationship between distance and each unit is listed below.
The spot size indicates 90% measured energy.
D:S = 75:1
