VIVOHOME Refrigerant Leak Detector Rechargeable — 15.8-inch Probe, 6-Hour Runtime

The VIVOHOME HVAC Refrigerant Freon Leak Detector is a handheld, rechargeable sniffer designed to locate refrigerant leaks quickly with adjustable sensitivity, audible/visual alarms, and up to six hours of run time.

This compact leak detector combines fast response and long battery life to help HVAC technicians, automotive mechanics, and refrigeration specialists trace refrigerant escapes across a wide range of gases. Built-in features such as three sensitivity levels, reset and peak recording, a 15.8-inch probe, and a large LCD make pinpointing leaks easier in tight spaces and noisy environments. The unit meets SAE J2791 and SAE J2913 standards and supports many common refrigerants, making it a versatile tool for routine checks and targeted diagnostics.

How sensitive is the VIVOHOME detector, and how quickly does it respond?

The detector provides three sensitivity settings and can detect leaks as small as 0.03 oz./yr on its highest setting. After a 30-second warm-up it responds within about three seconds, helping you identify leak locations fast without lengthy preparations.

• Maximum sensitivity up to 0.03 oz./yr for fine leaks
• Three selectable sensitivity modes to match different environments
• Warm-up time approximately 30 seconds for quick deployment
• Typical response time near 3 seconds for rapid feedback

What alarms and readouts tell me there’s a leak?

Detection is communicated both audibly and visually: an alarm beeps while the LCD shows color-coded bars for intensity. You can mute the audible alert if needed, and the large screen clarifies leak level at a glance for safer, less ambiguous inspections.

• Audible alarm with mute option for quieter checks
• Color-coded LCD bars: red for high, yellow for medium, green for none
• 2.8-inch display to read results from a short distance
• Regular buzzing at startup to indicate readiness; mute to silence

How does the reset and peak function improve leak finding?

The reset feature clears background concentrations so you can detect new or subtle leaks without false readings. The peak function captures the highest detected value, which helps you zero in on the primary leakage source during a sweep.

• Reset removes background gas build-up interference for clearer readings
• Peak value memory highlights the strongest leak detected in a scan
• 15.8-inch probe reaches narrow, awkward, or confined spaces
• Useful for step-by-step tracing when multiple leakage points exist

What about battery life and compatibility with refrigerants?

The detector uses a 3000mAh rechargeable battery that provides roughly six hours of continuous use and a long rated service life. It recognizes an extensive list of refrigerants including CFCs, HCFCs, HFCs, HFOs, hydrocarbons, blends, and many PFCs, so it’s suitable for diverse systems and modern refrigerants.

• Built-in 3000mAh battery for about six hours continuous operation
• Designed for up to 300 hours of overall use per SAE standards
• Compatible with common refrigerants like R12, R134a, R410a, R1234yf, R290, and many blends
• Low power consumption extends inspection cycles between charges

Who this is for: The VIVOHOME HVAC Refrigerant Freon Leak Detector suits HVAC technicians, refrigeration service pros, and vehicle AC mechanics who need a portable, reliable sniffer for routine maintenance, on-site troubleshooting, and retrofit work. It's also useful for facilities managers and appliance repair technicians who encounter a wide range of refrigerants and require clear visual and audible indications in cramped or noisy environments.
