Testo Smart Probes Differential Temperature/Pressure Kit The Testo Smart Probes Differential Temperature/Pressure Kit is an advanced set designed for use in a range of HVAC applications. These include measuring flow and return temperature on boilers, balancing radiators, gas pressure tests on boilers, and tightness testing. The kit operates using Bluetooth-enabled Testo smart probes in combination with the free Testo Smart Probes app for iOS and Android smartphones. Testo 115i Advanced Bluetooth Clamp Thermometer Two Testo 115i Advanced Bluetooth Clamp Thermometers are provided in the Differential Temperature/Pressure Kit. Now with a Bluetooth communication range of up to 100 metres, they are ideal for measuring inflow and outflow temperatures. They have a temperature measurement range of -40˚C to 150˚C with accuracy of ±1.3˚C and a resolution of 0.1˚C which makes them suitable for measuring both refrigeration and heating units. Each has a clamping diameter of 6mm to 35mm. Testo 510i Bluetooth Differential Pressure Gauge As a Testo Smart Probe, the Testo 510i Bluetooth Differential Pressure Gauge provided in the differential pressure/temperature kit communicates with the user’s smartphone via Bluetooth. It can send pressure measurements directly to a smart device and has a measurement range of 0 to 150hPa (60wc) with resolution of 0.1hPa and accuracy of ±0.2hPa + 1.5%. The meter also measures air flow velocity and volume flow and takes measurements via twin hose connections. It has a magnetic fixture and multiple practical applications.
