Frequently Asked Questions
The testo 557s acts as a central hub for all digital readings. It replaces multiple analog HVAC diagnostic tools by providing high-accuracy pressure, temperature, and vacuum data in one digital interface, ensuring more reliable system commissioning and troubleshooting.
Absolutely. The inclusion of wireless clamp thermometer probes and the 4-way valve block makes it ideal for heat pump servicing. It allows for simultaneous pressure and temperature monitoring without the clutter of extra wires, which is critical for the complex reversing cycles in heat pump systems.
The testo 557s is compatible with any standard refrigeration vacuum pump. While the pump performs the physical evacuation, the included testo 552i wireless probe allows you to monitor that vacuum digitally and remotely, ensuring a deep, moisture-free pull every time.
The testo 115i clamp thermometer units included in this kit use NTC temperature sensors for high precision. Because they connect via Bluetooth, they eliminate the "noise" or interference sometimes found in long-wired thermocouples, making them superior HVAC diagnostic tools for measuring superheat and subcooling.
