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 send live readings to the Smart App over a 100m Bluetooth range.
With flow temperature, return temperature, electrical power and current all visible on the same screen, engineers can assess coefficient of performance (COP) on site and generate a commissioning report — including photos and comments — before leaving the job. The 100m Bluetooth range on the 115i probes means the outdoor unit and indoor connections can both stay linked to the same app session, even when they're some distance apart.
Key Features & Benefits
Complete Heat Pump Testing Kit: Electrical (770-3) and thermal (2 x 115i) measurement in one case.
Testo 770-3 TRMS Clamp Meter with Bluetooth: Retractable pincer arm for tight heat pump panels, 0.01A–600A, 1V–1000V, power measurement and inrush current capture.
2 x Testo 115i Pipe Clamp Thermometers: Flow and return temperature measurement via NTC sensor, -40°C to +150°C, more accurate than a thermocouple.
Testo Smart App – All Instruments on One Screen: Live data from all three instruments simultaneously, with measurement curve graphing and PDF/Excel report generation.
100m Bluetooth Range (115i): Keeps flow and return, or indoor/outdoor measurement points, connected to the same app session.

Why Buy This Product?
Checking electrical and thermal performance separately means two site visits, or two instruments that don't share a common view of what's happening at the same moment. This kit puts both on the same screen in the Testo Smart App, so flow and return temperature can be read alongside power draw and current in real time, giving a practical way to assess COP on site rather than after the fact. The retractable pincer arm on the 770-3 and the clamp-on 115i probes mean neither instrument needs a circuit disconnected or a pipe cut into, and the 100m Bluetooth range keeps outdoor and indoor measurement points linked to the same session.
