Featuring an exclusive ergonomic design, the ProSim SPOT Light is the first comprehensive SpO2 functional tester to come in a handheld and easy-to-use device. SPOT Light is lightweight and flexible with three custom presets specially-designed to make it the fastest and easiest-to-use pulse oximeter analysis device on the market today for SpO2 functional testing. A helpful LCD display and three simple buttons make it effortless to rapidly change parameters and view each signal output sent to the pulse oximeter at a glance. An interchangeable, long-life battery ensures uninterrupted all-day operation without need to connect to a power supply. SPOT Light sets up in seconds to send Peripheral capillary oxygen saturation (SpO2), heart rate, perfusion, transmission, artifact noise, and eight different manufactures custom r-curves to a pulse oximeter or patient monitor. It is designed to take the abuse of everyday use, including the stresses of transportation, moving from room to room and device to device, and the occasional fall from the workbench.
