Testo Monobloc Heat Pump Testing Kit – 770-3 Clamp Meter + 2 × 115i Pipe Clamp Thermometers Bluetooth Testo Smart App This kit combines the Testo 770-3 True RMS Clamp Meter with two Testo 115i Bluetooth Pipe Clamp Thermometers, giving heat pump engineers a way to check both electrical and thermal performance of a monobloc heat pump in a single site visit. All three instruments connect to the free Testo Smart App for live data, graphing and report generation, and are supplied in a tough transport case. The 770-3's retractable pincer arm reaches into tight areas of a heat pump electrical panel without needing to disconnect anything, measuring current draw, voltage, active/reactive/apparent power and inrush current at start-up. The two 115i clamps are fitted to the flow and return pipes, using NTC sensors to measure pipe temperature remotely and
