Aprvtio ALD-200 Refrigerant Leak Detector — R454B & R22 Compatible, 2.8" TFT Display, High Sensitivity

The Aprvtio ALD-200 is a professional-grade refrigerant leak detector that quickly finds micro leaks across A1, A2L and A3 refrigerants including R454B and R22.

Designed for HVAC technicians, service shops, and advanced DIYers, the ALD-200 combines a next-generation heat diode sensor with an easy-to-read 2.8-inch TFT color display and smart modes to speed diagnosis on heat pumps, air conditioners, refrigeration systems, and automotive A/C. The unit balances high sensitivity with field durability and features intended to reduce false positives and simplify routine calibration.

How sensitive is the ALD-200 at locating tiny refrigerant leaks?

The ALD-200 detects minute leaks with sensitivity adjustable down to about 0.14 oz./year, allowing you to locate hairline leaks that soap tests and many dye methods miss. Its heat diode sensor is tuned for broad refrigerant families so you can trust readings across modern blends and hydrocarbons.

• Adjustable sensitivity for micro-leak hunting.
• Heat diode sensor optimized for A1/A2L/A3 refrigerants.
• Detects tracer gases like H2/N2 for pressure-testing support.

What visual and audible indicators help diagnose a leak on-site?

The detector shows concentration and trends on a vibrant 2.8-inch TFT color display while increasing beep frequency signals rising leak levels. If silence is needed during inspections or in customer settings, the mute function temporarily disables audio cues without losing visual feedback.

• Color display for clear readings in dim or bright conditions.
• Audible alarm with variable beep rate reflecting leak strength.
• Mute button for discreet operation while monitoring screen values.

What smart features reduce false alarms and speed troubleshooting?

The ALD-200 includes Peak Mode to capture the highest detected reading and a Reset/auto-zero calibration to re-establish baseline air levels, which helps cut down on nuisance alerts. These functions, combined with a recommended warm-up and calibration routine, improve consistency across job sites.

• Peak Mode preserves maximum leak readings for review.
• Auto-zero and Reset reduce drift and false positives.
• Simple warm-up and calibration steps for reliable performance.

Is the ALD-200 durable enough for busy service work?

Built for field use, the housing is oil-resistant and impact-resistant so the unit stands up to rough handling and oily environments common in HVAC service. A rechargeable battery supports a full service day, and the physical design prioritizes ease of probe handling and storage.

• Oil- and impact-resistant enclosure for job-site resilience.
• Rechargeable battery for extended on-site operation.
• Compact probe and ergonomic body for fast inspections.

Who this is for: The Aprvtio ALD-200 is suitable for HVAC technicians, refrigeration service professionals, fleet and automotive A/C shops, and experienced DIYers who need near-professional sensitivity without the premium price. It is especially useful when working with modern refrigerant blends, flammable hydrocarbon charges, or tracer gas tests where accurate micro-leak detection and reliable readouts speed repairs and reduce downtime.
