AUTOMATED SMOKE SPOT TESTER
Perform digital smoke spot testing in less than 60 seconds with the highest accuracy (to smoke spot 0.1) and repeatability. Eliminate troublesome look-up charts, avoid errors caused by condensation, and prevent the irregularity of manual pumping. The 308 draws the precise volume then digitally analyzes exhaust. The large, backlit display presents the "real" smoke spot number with remarkable ease and accuracy.
KEY POINTS

• One hand operation
• Large backlit display
• Integrated moisture removal
• Integrated filtration
• Rechargeable
• Fast «60 secs.)
