Fields of Application:


Auto Services


Engine and Exhaust troubleshooting Low Compression: Scan manifold temperature to determine low compression.


Ignition System Problems: Scan manifold temperature for misfire condition.


Incorrect Fuel/Air Mixture: Measure and compare exhaust system components for correct fuel/air mixture.


Catalytic Converters: Scan both sides of the catalytic converter for temperature differences.


Cooling System Diagnostics


Check for overheating problems or if parts need to be replaced.


Radiators: Scan radiators for core restrictions.


Thermostats: Easily measure thermostat temperature.


Coolant Sensors: Measure coolant temperature sensors and manifold air temperature sensors and Climate Control


Check heaters, air conditioners, and vents quickly and easily for malfunction.


Heaters/AC Vents: Check heating and cooling systems output.


Temperatures significantly higher than ambient or varied temperatures of rotors, drums or bearings indicate excessive wear.


Brakes/Sealed Wheel Bearings: Diagnose brake bias and uneven braking.


HVAC Related


Check Low Side and High Side Pipe temperatures and get Sub cooling and Supper heating temperature


Check room temperatures fast


Check ambient and outlet temperature and see if a cooling or heating system works or not FAST


Find weak insulation area in walls and fix it without pressurizing the room/house, save time and money


Check temperature point to point, Wall by wall, room by room and find the weak insulated areas and save money on heating/cooling bills


find the hot spot in the circuit board/element and know the element which is going to break soon


Check temperatures on fast moving element safely, etc
