The Index 2 is a lightweight, portable tool that includes preloaded manufacturers’ R-curves and the ability to define other “makes" for testing pulse oximeters.
Motion presets, player mode, transmission level control (TLC), and computer commands boost testing ability. The Index 2 can also be configured to include an optional electrical simulation feature with probe test. Optical and electrical simulations allow technicians to isolate problems quickly. The probe test identifies defective probes with quantitative test results.
