Description
Product Overview
The VIVANTECH VVA101 is a professional-grade refrigerant gauge designed for automotive air‑conditioning diagnostics and service. Housed in a rugged ABS case measuring 10.6 x 11 x 3.9 inches and weighing 5.6 lb, it combines durability with portability. The large backlit LCD provides clear readouts of high‑ and low‑side pressures in PSI, kPa or Bar, and automatically switches between temperature units for evaporation and condensation monitoring. Equipped with 1/4″ SAE ports, the unit supports a wide range of refrigerants and includes core‑depressor fittings for secure hose connections. Three AA batteries are supplied for immediate use.
Usage
This gauge is ideal for automotive service centers, mobile technicians, and DIY enthusiasts working on car, truck or light‑commercial AC systems. Use it to charge refrigerant, verify system pressures, perform deep vacuum evacuations, or conduct leak tests during routine maintenance or after repairs. The built‑in vacuum test mode ensures the system is fully evacuated before charging, while the leak‑test function tracks pressure decay over time, helping pinpoint leaks quickly. 
Why Choose Us
VIVANTECH’s reputation for precision engineering is reflected in the VVA101’s robust construction and accurate sensors. The gauge undergoes strict quality control and is calibrated to meet industry standards, guaranteeing reliable data on every use. Its intuitive interface reduces training time, and the inclusion of essential accessories—nylon sealing gaskets, a copper plug, and batteries—means you can start working right out of the box. Low‑battery warnings and a pressure‑release valve further enhance safety and operational confidence.

FAQ
What refrigerants are compatible with this gauge?
The VVA101 supports all common automotive refrigerants, including R‑134a, R‑1234yf, and R‑152a. Select the appropriate refrigerant type via the unit’s menu before charging.
How often should the gauge be calibrated?
For optimal accuracy, we recommend calibration at least once a year or after any impact that could affect the sensor.
Can the gauge be used for residential AC systems?
While primarily designed for automotive applications, the gauge can measure pressures in residential split systems, provided the correct adapters are used.
What is the battery life under normal operation?
With three AA batteries, the gauge typically operates for up to 150 hours of continuous use. A low‑battery indicator alerts you before power loss.
Is there a warranty?
VIVANTECH offers a one‑year limited warranty covering manufacturing defects and sensor accuracy.
