THE TERPOMETER is the world’s first thermometer specifically calibrated for quartz. Protected by US Patent no.10,690,553 we designed these devices with the 710 connoisseur in mind. The LCD screen will display the real time temperature of the surface upon contact. The screen illuminates GREEN suggesting the precise temperature to apply extracts for optimal effects and flavor. The Terpometer truly provides the most precise technique to enjoy extracts. Problem Solved.
