VIVOHOME VH1747 Digital HVAC Manifold Gauge Set with 2 Wired Temperature Clamps

Choosing HVAC service equipment often comes down to whether you need a straightforward pressure check or a tool that also tracks line temperatures. The VIVOHOME VH1747 combines both readings in one digital manifold.

Its two wired temperature clamp probes and three-hose setup support practical system checks, while the backlit LCD keeps readings visible in dim work areas. It is designed for refrigeration and air-conditioning installation, testing, and maintenance.

Highlights

The VH1747 measures pressure and temperature at the same time, so technicians can view both sides of a system and the connected line temperatures in one place. It supports 88 refrigerant types and calculates superheat and subcooling temperatures, helping organize common HVAC diagnostic readings. Pressure testing, leak testing, and vacuum measurement are among its stated functions.

The pressure measurement range is -14.5 to 800 psi, with ±0.5% FS pressure accuracy. Temperature readings span -58°F to 302°F, with ±0.9°F accuracy. The display offers a backlight, pressure readings can be switched among multiple units, and temperatures can be shown in Celsius or Fahrenheit. An automatic power-off function shuts the gauge down when it detects inactivity.

The set includes two wired temperature clamps and three heavy-duty hoses with locking valves. The gauge also has a hook for hanging it during a job, and the included carry case makes it easier to transport and store between service calls. Customers often praise the unit’s functionality and ease of use, feedback on temperature readings and accuracy is mixed, so the stated measurement specifications remain the clearest basis for choosing it.

Who it’s for

This manifold set is suited to HVAC technicians and others servicing compatible refrigeration or air-conditioning systems who want pressure and pipe-temperature readings together. The clamps connect to the AC pipes to capture real-time temperatures, while the manifold and hoses provide a setup for system analysis. Its support for a broad range of refrigerants makes it useful across different service tasks rather than limiting it to a single refrigerant type.

If your priority is a compact digital setup for readings and calculations, the VH1747 brings those functions together. A simpler gauge focused only on pressure may suit a narrower task, this set adds temperature probes and superheat and subcooling calculations for a broader diagnostic workflow.

How to use it

Connect the three hoses to the system and use the wired clamps on the air-conditioning pipes to measure line temperatures. Select the refrigerant and preferred pressure and temperature units, then read the measurements on the LCD. The simultaneous pressure and temperature display supports checks during installation and maintenance, while the backlight helps when the work area is dim. The locking valves and included anti-freeze safety valves are part of the hose setup, handle refrigerant service equipment according to the system and applicable safety procedures.

The digital gauge requires three AA batteries, which are not included. Its automatic power-off feature is designed to shut the unit down after idle status is detected.

Before you decide

Which refrigerants does the gauge support? It supports 88 refrigerant types, including R134a, R410a, R32, R1234yf, and R454B.

Can it measure temperature as well as pressure? Yes. It reads pressure and temperature simultaneously and includes two wired clamp probes for checking temperatures at AC pipes.

What is included with the set? The listed setup includes the digital manifold gauge, two temperature clamps, three hoses with locking valves, anti-freeze safety valves, and a carry case. The gauge requires three AA batteries, sold separately.

When it makes sense

Choose the VIVOHOME VH1747 when HVAC service calls benefit from seeing system pressure and line temperature together, with calculations for superheat and subcooling available across supported refrigerants. Its clamps, hoses, readable backlit display, and carry case make it a practical fit for technicians who need a digital manifold set for installation, testing, and routine refrigeration or AC maintenance.
