The testo AC & Refrigeration test and load kit includes two testo 549i high-pressure measuring instruments, three testo 605i thermohygrometers and three testo 115i clamp thermometers for pressure, (air) temperature and humidity measurement. In conjunction with a smartphone or tablet, the kit is ideally suited to servicing and troubleshooting on air conditioning and refrigeration systems, as well as their installation. The testo 549i and testo 115i can be quickly and easily attached directly at the pressure connection or the temperature measuring point. It is now considerably easier to work at a longer distances, thanks to improved wireless connection to your smartphone or tablet.
The measuring values of both instruments are transmitted via Bluetooth to the testo Smart Probes App installed on your terminal device enabling convenient and flexible readout there. In addition, the App enables automatic calculation of evaporation and condensation temperatures as well as of heating/cooling capacity/output. All measurement data is viewable either as a diagram or a table. Finally, the measurement data report can be e-mailed directly as a pdf or Excel file.
The Redfish iDVM 550 clamp power meter with Bluetooth Low Energy (BLE) is a hand held meter that combines both reliable and robust measurement capabilities with the connectivity to mobile devices provided by BLE. The meter provides the ability to measure AC current, AC/phase/power factor (PF), and non contact voltage (NCV). Dwyer A-303 Static pressure tips are required for accurate static pressures when measured in ducts, across filters, coils or heat exchangers. These magnetic tips allows for hands free use and quick accurate measurement.
Details on InRush Current Measurement:
The surge in current at the start up of many electrical devices is called the InRush current. It often embodies the energy required to "get things moving" and rapidly drops to the running current of the device. You must use a specially designed clamp type meter (like the Redfish iDVM 550) to measure InRush. The iDVM 550 is the least expensive meter that we have found that incorporates the InRush feature.
Inrush current may be higher than the rating of the device's circuit breaker, yet the breaker (or overload) does not trip as it is a function of total energy or time vs current. It is common to see InRush currents that are 4 to 10 times greater than the normal running current. InRush current analysis is often done over time in conjunction with preventive maintenance, thus allowing you to watch a system trend and see if the motor or motor circuitry is degrading.

The Testo Smart Probes App combines the
power of your smart phone/tablet with the
accurate measurements of your Smart Probes.
The operation and display of the instruments are
communicated via Bluetooth to the App on your smart phone or tablet . The Smart Probes App uses the measurements to create custom reports (including added photos and comments).
Information and reports can be saved as files
and/or sent by e-mail. For Apple iOS and Android.
