Aprvtio ALD-200 Refrigerant Leak Detector — Rechargeable 3-in-1 Heated Diode Sensor, Color TFT Display

The Aprvtio ALD-200 is a rechargeable, high-sensitivity 3-in-1 refrigerant leak detector that finds micro leaks in A1, A2L and A3 refrigerants using an upgraded heated diode sensor and offers audible/visual alarms on a 2.8-inch color display.

The ALD-200 is built to help HVAC technicians and serious DIYers locate refrigerant leaks faster and more reliably than simple soap tests or dye. Its advanced heat-diode sensor distinguishes a broad range of refrigerants — including R32, R454B, R410A, R134A and hydrocarbons like R290 — while portable, oil-resistant construction and a rechargeable battery make it field-ready for service vans, rooftops and basements.

How sensitive is the detector and how small a leak can it find?

This unit offers adjustable sensitivity down to approximately 0.14 oz./year, enabling detection of micro-leaks that standard visual methods miss. Peak capture mode helps lock the largest reading while you probe tight connections or welds.

• Adjustable detection threshold for targeting tiny leaks
• Peak Mode records highest concentration for later review
• Heated diode sensor tuned for refrigerant gases and tracer mixes

Which refrigerants and gases does the ALD-200 detect?

The ALD-200 is designed as a true 3-in-1 solution for A1, A2L and A3 classes, plus many legacy and blend refrigerants. It also responds to common tracer gases like 5% hydrogen/95% nitrogen, expanding its usefulness for complex diagnostics.

• Compatible with R32, R454B, R410A, R134a, R290 and many CFC/HCFC/HFC/HFO blends
• Accepts hydrocarbon refrigerants and common tracer gas mixes
• Useful on HVAC, refrigeration, automotive A/C and heat pumps

What alarms and display features help when working in noisy or dim environments?

A bright 2.8-inch TFT color display shows concentration readings and status icons for quick interpretation, while an audible tone increases frequency with leak strength. A mute button lets you work quietly when required, and the reset function minimizes false alarms by recalibrating the sensor.

• Color TFT screen for clear readings in low or bright light
• Audible alarm with progressive beep rate and a manual mute option
• Reset function and auto-zero calibration reduce false positives

How durable and job-site ready is this leak detector?

The ALD-200 is built with oil-resistant, impact-aware housing designed to handle everyday service conditions. Long battery life from the rechargeable pack and straightforward setup make it practical for a full service day without frequent interruptions.

• Oil-resistant exterior and impact-tolerant construction
• Rechargeable battery supports extended field use
• Simple warm-up and auto-zero calibration for consistent results

Who is this for: The Aprvtio ALD-200 is aimed at HVAC professionals, refrigeration technicians, fleet maintenance teams, and experienced DIYers who need a compact, accurate leak sniffer capable of handling modern low-GWP refrigerants and traditional blends. If you require precise micro-leak detection, rugged portability, and broad refrigerant coverage without the cost of a lab-grade analyzer, this detector is engineered to meet those needs.
