Brand & Model
Manufacturer / Distributor: Dynamics
Specific Model / Product Line: Thermex Range KL5 Infrared Thermometers

Advanced Display Features
Graphic History Display: The screen features a unique graphic panel that displays temperature changes visually as a picture, storing and plotting the data for the last ten measurements.
Comprehensive Screen Layout: The LCD simultaneously displays:
Main real-time temperature reading: Graphic trend display, Configured Emissivity value ($\mathcal{E}$), Current status bar & battery life indicator, Laser condition and trigger lock icons

Operation
Targeting System: Uses circular laser sighting where the laser circle outlines the exact spot size being actively measured.
Optical Focal Ratio: Operates at a precise distance-to-spot ratio of 60:1 at the focus point.
Battery Requirements: Runs on two standard AA alkaline batteries (referenced as R6, AA, or UM3).
Battery Endurance: Delivers a minimum continuous battery lifespan of 10 hours.

Core Specifications
Temperature Range: -30°C to 900°C (-25°F to 1600°F)
Optical Resolution (Distance to Spot): 60:1 (Excellent for long-range or small-target measurements)
Accuracy: ±1% of reading or ±1°C (±1.5°F), whichever is greater
Display Resolution: 0.1°C (0.2°F)
Spectral Range: 8 to 14 µm
Response Time: 250 milliseconds (95% response)

Key Features
Laser Targeting: Displays the actual spot size being measured.
Adjustable Emissivity: Range can be adjusted manually; features a built-in pre-set chart for common materials (e.g., Concrete: 0.95, Glass: 0.85, Iron: 0.70).
Alarms: High Alarm (HiAl) setting that triggers both a visual flashing light ("Laserflash") and an audible buzzer.
Measurement Modes: Tracks and displays minimum and maximum temperature values simultaneously on the bottom of the screen.

Power & Hardware
Batteries: Power by 2 x 1.5V AA Alkaline batteries.
Physical Mounting: Built-in 1/4"-20 UNC tripod mount on the base.
Internal Settings (DIL Switches): Located in the battery compartment to permanently toggle:
Trigger Lock (On/Off) / Buzzer & Backlight (On/Off)
