BIOTEK Index 2 Series SPO2 Simulator

Index 2 SpO2 Simulator

Index 2 Series combines Fingersense our new patented simulated finger with the first comprehensive probe and electronics test to fully analyze pulse oximeters and probes.

Index 2’s new "Fingersense" assures compatibility with virtually any oximeter on the market today. No hardware or firmware upgrades are necessary. Fingersense incorporates new electronic physiology that instantly recognizes and adapts to all types of oximeter simulation technologies. Use its new user definable "make" feature and pulse oximeter makes that are not included within Index can be verified with acceptable accuracy. With the rapid increase of SPO2 monitors, the new physiology in the electronics help insure that Index 2 will be compatible with your pulse oximeter. 

Electrical simulation for testing the pulse oximeters alone and probe testing is now available in the "E" version. This allows you to test the oximeter without the probe in-line and all simulations are available. The probe analysis includes:


LED test: Voltage drop across both red and infrared diodes

Photodiode test: Detector response to a 1 mA illuminating current (both red and infrared)

Resistive wire check: Resistances between all wires

Index 2 lets you simulate arterial oxygen saturation (SPO2) from 35% to 100% oxygenation. Heart rate can also be varied from 30 to 250 BPM. In addition, Plethysmographic waveforms can be set from 0-100% amplitude, simulating the range from no pulse up to a very strong pulse. These basic features allow Index 2 to simulate several different patient conditions such as: 

Normal Patient

Patient with a weak pulse

Geriatric patient

Obese patient



Bio-Tek's test simulations verify the pulse oximeters SpO2 and heart rate alarms for response time. Use Index 2 for pre-purchase evaluations to determine how well different pulse oximeters respond to artifacts such as motion, ambient sunlight and 50/60 Hz artificial light. 

In addition, Index 2 comes with full computer control, a built-in RS232, and a printer port. Test results may be transferred to Bio-Tek's Equipment Management System via OTIS for Windows (OFW) or sent directly to an attached printer for hard-copy results.
