User Manual
Thank you for purchasing the QM7410. This product is capable of non-contact (infrared)
temperature measurements at the touch of a button. The built-in laser pointer increases target
accuracy while handy push-buttons combine for convenien , ergonomic operation. The QM7410
can be used to measure the temperature of objects with a surface that cannot be measured by
traditional contact thermometers. Proper use and care of this meter will provide years of usage.
2.Features
• Rapid Detection Function
• Precise Non-Contact Measurements
• Single Laser Sighting
• Unique Flat Surface, Modern Housing Design
• Automatic Data Hold
• “MAX/MIN” Function
3.Wide Range Application
Food preperation, safety and fire inspectors, plastic molding, asphalt, marine, screen printing,
measure ink and dryer temperature, HVAC/R, diesel and feet amaintenance, etc.
4.Safety
• Use extreme caution when the laser beam is turned on.
