Minus Forty Technologies Corp. introduces Smartlock, a dual functional, fully integrated and NAMA listed health timer. Smartlock will only lock out freezer/cooler when the preset parameters are reached in accordance with state health requirements eliminating costly and time consuming trips to micro market sites to reset the freezer/cooler. The system even includes a battery back-up so it continues to monitor, record temperature and function as a safety lock even during power outages, making Smartlock truly a “smart lock.”
