I got the following from an October 10th 2008 PR. If I am not mistaken, 1000 single sensor units would be 5 million in sales.
"The revenue model for the BioHarp comes from both the hardware and software sales. The single sensor unit will sell for $5,000 US dollars and the five sensor unit will be $30,000. The software will be sold on a license agreement wherein BioHarp UNI US will charge $19.99 per month per patient license, thereby creating a continued revenue stream once the unit hardware is sold. Naturally, if we have groups that are purchasing thousands of units, we will have a discount structure to these monthly fees. With the patient potential in the millions, our revenue model will be very strong and consistent for years to come.
