Testo Smart Probe Set - Servicing and installing air conditioning, heating and refrigeration systems has never been easier Take advantage of the compact testo smart probe set and quickly and reliably carry out installation and troubleshooting of heating and cooling systems. The set includes the testo 115i pipe-clamp thermometer which enables precise reading of temperature in pipes and the testo 549i, that provides accurate measurements of high and low pressure. Combined, the two smart probes also offer calculations of individual refrigeration parameters for up to 90 refrigerants. Automatic calculations of superheating and subcooling, as well as live data feed integration and progressive reports makes your work easier and more efficient. Quickly view and send measurement data and custom reports as PDF or Excel.
