Specialized Models for Specialized Applications

Advanced applications and processes need specialized tools like the Raytek 3i IR (infrared) thermometer. The Raytek 3i series of noncontact thermometers measures surface temperature in places other thermo-meters cannot. With a choice of spectral responses, temperature ranges, laser sighting options and on-board data logging capabilities, the Raytek 3i meets the individual requirements of demanding users.

Overcome the limitations of contact thermometers in manufacturing plants with Raytek 3i series infrared thermometers. For the most accurate readings in hot environments, the 3i thermometer compensates for the energy reflected by the background around the target. Reflected background energy compensation allows for accurate measurement even when the area measured is reflecting energy from nearby objects with higher temperatures;
for example, inside a furnace. Varying spectral responses, laser sighting systems, and distance-to-measurement spot ratios ensure the Raytek 3i temperature measurements are precise.

LT and LR

For maintenance and quality control applications, the Raytek 3i Low Temperature (LT) and Long Range (LR) models are available for various temperature range and optical requirements. The strong 105:1 distance-to-spot ratio of the 3i LRL2SC thermometer combined with a –30 to 1200°C (-20 to 2200°F) temperature range and scope permits easy temperature measurements of elevated objects at great distances, such as electrical connectors in towers.

Useful in the following manufacturing situations:

• Utilities
• Electrical Connectors
• Plant Maintenance
• Paper Production
• Fire Safety

1M and 2M

Raytek high temperature infrared thermometers, such as the 3i 1M & 2M models are ideal for foundry and processing operations, such as heat treating, tempering and forging.

Due to the high-resolution 180:1 optics of the Raytek 3i 1M unit, it can take the approximate temperature measurements of molten glass by measuring the surface temperature of the port arch and bridge wall. Measuring the surface temperature of regenerator stacks or furnace melts may also assess the possibility of brick damage.Ideally suited for:

• Iron
• Steel
• Metal Refining
• Foundry and Processing Operations
• Ceramics
• Semiconductor
• Chemical Furnaces
• Flare Stack Monitoring
• Petrochemical Furnaces

G5 and P7

Accurately measure glass and plastics processing with specialized spectral responses using the Raytek iG5 or 3iP7 unit. The 3iG5 model is a 5-micron instrument designed for glass manufacturing and recycling, and is useful for temperature measurements of float sheets and gobs. The 7.9-micron Raytek 3iP7model is designed for applications in producing and converting film plastics.

Well suited for many processes within glass and plastic manufacturing.

G5:

• Annealing
• Forming
• Sealing
• Laminating
• Bending

P7:

• Lamination
• Flexo-Printing
• Film Orientation
• Extrusion and Coating
• PET, flouroplastic, Teflon®, acrylic, nylon (polyanide) cellulose, acetate, polyimide, polyurethane, PVC, polycarbonate
