SMART SENSOR AS842A Infrared thermometer The most basic design consists of a lens to focus the infrared (IR) energy on to a detector, which converts the energy to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature variation. Infrared Thermometers allow users to measure temperature in applications where conventional sensors cannot be employed. Specifically, in cases dealing with moving objects ( i.e., rollers, moving machinery, or a conveyor belt), or where non-contact measurements are required because of contamination or hazardous reasons (such as high voltage), where distances are too great, or where the temperatures to be measured are too high for thermocouples or other contact sensors.

| Emissivity : Most organic materials and pa-inted or oxidized surfaces have an emissiv-ity of 0.95 (preset in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover the surface to be measured with mas-king tape or flat black paint. Measure the tape or painted surface when the tape or painted reach the same temperature as the material underneath. | |||

Diagram and LCD display:
 | Introduction Compact, rugged and easy to use. Just aim and push the button, read current surface temperature in less than a second. Safely measure surface temperature of hot, hazardous or hard-to-reach objects without contact. |
Diagram description reading with HOLD icon for 7 sec. Built in auto power off in 30sec. (2) Laser / back light button: when back light turn (3)-(6) key functions: difference of current reading. When reading over trigger, LCD display HI icon with BiBi audio sounds. | |
| LCD display: A data hold icon B scanning icon C laser on icon D back light on icon E battery power icon F measuring unit G measuring reading | |
Distance & spot size: As the distance from the object increase, Make sure the target is larger than the units spot size. The detected parts diameter need up to 1.5cm. But the best testing distance is 20cm.when detected parts size is 10*10cm | |
Attention: hole is the main Parts measure the temperature 2. Do not point laser directly at eye or in-directly off reflective surface. |
Quick Start Instruction:
| Step 1 | Press battery door clip, install battery correctly. Pull the trigger, LCD display reading& battery icon. Release the trigger and the reading will hold for 7 seconds. |
| Step 2 | Locating a hot spot: To find a hot spot aim the thermometer outside the area of interest, then scan across with up and down motions until you locate the hot spot.(please turn on the laser for accurate measuring) |
Users Guide:
| How it works | Infrared thermometer measure the surface temperature of an objec,t. The units optical system sense the object s emitted energy with different wavelength. It is, collected and focus onto a detector. The unit s electronics system translated the information into a temperature reading which is displayed on the unit. |
| Cautions | Infrared thermometer should be protected from the following: --EMF (electro-magnetic fields) from welders, induction heaters. --Thermal shock (cause by large or abrupt ambient temperature changes allow 30 minutes for unit to stabilize before use). --Do not leave the unit on or near objects of high temperature. Do not point laser directly at eye or in-directly off reflective surface. |
