⚙️ Tired of squinting at analog gauges and doing manual calculations?
Traditional manifold gauges force you to interpret tiny needles, switch hoses for heat pump mode, and calculate superheat/subcooling manually—leading to errors and wasted time. You might need multiple tools (vacuum gauge, thermometer, pressure gauge) and still lack data logging.
✅ Elitech EMG-40V changes everything. A single digital manifold with a bright touch screen replaces a bag of tools. It connects to your phone via the Elitech Tools App, automatically calculates superheat/subcooling for 88 refrigerants, performs leak tests with temperature compensation, and records 100,000 data points. No more guesswork, no more hose swapping.
Supported Refrigerants (88+)
Automatic superheat/subcooling for 88 refrigerants. Frequently used ones can be saved as favorites.

Frequently Asked Questions
Does the EMG-40V work with both R22 and new refrigerants like R32 and R454B?
Yes, it supports over 88 refrigerants including legacy (R22, R502) and new eco-friendly ones (R32, R454B, R1234yf, etc.). You can also save your most-used refrigerants to the top of the list for quick access.
How long does the battery last? Is it rechargeable?
The built‑in rechargeable battery provides up to 20 hours of continuous use on a full charge. It charges via USB‑C (adapter included).
Do I need the app to use the manifold?
No, the manifold works as a standalone unit with its touch screen. However, the Elitech Tools App adds remote monitoring, data export, and unified control of multiple Elitech devices—making your workflow much smoother.
Can I use it for heat pump systems without changing hoses?
Absolutely. The 4‑way valve design, combined with automatic heat pump mode, lets you switch between heating and cooling without touching the hoses—saves time and reduces the risk of contamination.
What’s included in the box? Do I need to buy extra hoses or clamps?
The kit comes with everything you need: the manifold, vacuum transmitter (T‑joint), two temperature clamps, bent joint, four refrigerant hoses, power adapter, USB‑C cable, manual, and a hard carrying case. No extras required.
How accurate is the vacuum measurement?
The vacuum sensor has an accuracy of ±10% of reading ±10 micron from 0‑10,000 micron, and ±20% of reading from 10,000‑19,000 micron—enough for deep vacuum testing in HVAC systems.
Can I export the logged data?
Yes, the manifold stores up to 100,000 data points. You can export them via USB‑C to a computer for analysis or reporting.
Does it come with a warranty?
Elitech offers a 1‑year limited warranty against manufacturing defects. Register your product on our website for warranty service.
