testo 115i - clamp thermometer with smartphone operation
The testo 115i is ideal for professional use in air conditioning, refrigeration and heating applications and enables particularly flexible temperature measurement. In daily practice, it stands out thanks to its convenient handling via smartphone connection, which allows for easy evaluation and documentation. This measuring device therefore offers a modern alternative to conventional temperature sensors. Similarly powerful instruments such as the [testo 549i] offer comparable advantages, but the testo 115i focuses more on flow and return temperatures in refrigeration and air conditioning systems.
Precise and flexible measurement options
The wireless approach of the testo 115i ensures that measurements at widely separated measuring points are much easier to carry out. The measurement values can be viewed immediately in the associated app via a Bluetooth connection to a smartphone or tablet. There, a graphical display allows temperature curves to be monitored in real time. Similar to the [testo 605i], the device offers a practical measuring range and a robust design for everyday service and installation tasks in the HVAC sector.
Technical features at a glance:
- Measuring range from -40 to +150 °C (NTC)
- Accuracy ±1.3 °C (in the measuring range -20 to +85 °C)
- Resolution of 0.1 °C
- Operation at ambient temperatures between -20 and +50 °C
- Bluetooth range up to 100 m
- Power supply via 3 AAA microcells (battery life of approx. 150 hours)
- Compatible with A2L and A3 refrigerants
Other features include the lightweight plastic housing and compact dimensions of 183 × 90 × 30 mm, which enable ergonomic handling. For optimum process reliability, the testo 115i is also equipped with a stable measuring claw mechanism that reliably encloses the measuring point.
Various application examples
- Maintenance of refrigeration and air conditioning systems: The measuring device is particularly suitable for verifying flow and return temperatures in refrigeration systems. The monitoring of temperature changes in compressors is also precisely mapped.
- Check heating systems: Thanks to NTC sensors, heating circuits can be quickly checked for efficiency, for example when balancing the flow temperature in combination with external pressure measurements.
- Troubleshooting in temperature circuits: As soon as unusual temperature fluctuations occur, the app connection enables complete documentation and thus targeted diagnosis.
- Commissioning and installation: Newly installed air conditioning units or heat pumps can be monitored in real time in order to make correct settings and detect deviations at an early stage
