SKU: 05645582

The testo 558s offers an intuitive app feel in the manifold, with touchscreen and clear measurement graphs on a large colour display. In addition to the touchscreen, the manifold can also be operated via keys when working with gloves. Thanks to its A3 and A2L compatibility, high robustness with IP54 and hybrid charging system comprising rechargeable and non-rechargeable batteries, the manifold is ideal for every situation.

Intuitive operation

The touchscreen operation and large colour display make configuration, control and documentation much easier. This makes operation of the manifold faster and more intuitive. When working with gloves, the manifold can be operated using keys in addition to the touchscreen.

Always up to date

Thanks to free updates (OTA), the manifold can be regularly updated. This allows, for example, new refrigerants to be added and connectivity to new products to be enabled.

Data logging

Readings can be recorded for up to 30 minutes and displayed as trend curves. This allows anomalies to be quickly identified. Optionally, the manifold can be extended to a logging capacity of 72 hours.

Ready for any refrigerant

For maximum safety, the manifold is also compatible with Class A3 and A2L flammable refrigerants. With a wide selection of 96+ refrigerants, all common refrigerants are stored in the manifold. Frequently used refrigerants can be marked as favourites for quick retrieval.

1. TESTO552i Wireless Vacuum Probe

05642552

ThisTESTO05642552,TESTO552i Wireless Vacuum Probe is a quality app-controlled vacuum probe with Bluetooth connectivity. The vacuum probe delivers reliable measurement results and is robust and easy to use. It provides optimum support for proper evacuation of refrigeration and air conditioning systems and heat pumps.

2. Testo 115i – Clamp Thermometer Operated Via Smartphone

0560211502

Combined with a smartphone or tablet, the testo 115i clamp thermometer is the ideal temperature-measuring instrument for servicing and troubleshooting air conditioning and refrigeration systems and installing them. It can also be used to measure flow and return temperatures.

• Measurement of the flow and return temperature of heating systems.
• Measurement of temperatures in refrigeration systems to calculate superheating and subcooling.
• Easy to use at measuring points that are far apart.
• Rapid detection of temperature changes via graphical progress display.

Professional measuring technology is now mobile: when it comes to temperature measurements at widely spaced measuring points, the testo 115i makes things much easier thanks to a wireless connection to the smartphone or tablet. Individual refrigeration system parameters can also be calculated when used in conjunction with the testo 549i pressure measuring instrument.

3. Testo 770-3 – Clamp meter with Bluetooth

0590770302

Non-contact measurement on tightly packed cables is really easy and reliable with the testo770-3 clamp meter. Its innovative grab mechanism will make your work easy. The most powerful model in the clamp meter series, it offers lots of additional functions for those challenging tasks that you are faced with on a daily basis, e.g. connection to the testo Smart App and other Testo measuring instruments. Thanks to its increased resolution, the clamp meter delivers highly precise results even in the lower current range.
