Refrigerant Leak Detector, Aprvtio ALD-200 3-in-1 Freon Leak Detector Tester A3 A2L A1 Refrigerants Compatible, Rechargeable, Multipule Alarm, Heated Diode Sensor for HVAC R32 R454B R410A R134A R290

I’ve been using this leak detector for a few weeks now and it’s been super reliable. The sensitivity adjustment is great — I was able to track down a small R410A leak that I probably would’ve missed with my old detector. The screen is clear and easy to read, and I like that you can mute the alarm when working in tight or noisy spaces. It feels solid and durable, and the battery easily lasts through a full day of service calls. Overall, a really good value for both HVAC work and DIY use.

I used the ALD-200 to find a small refrigerant leak in my AC system, and it detected it immediately. The display is bright and easy to read even in the dark attic. Very impressed with the sensitivity and accuracy.

It works well but has short battery life.

Great for home DIY projects too. I found a slow leak in my basement AC system that I would never have noticed. The visual display is clear, and the alarms make it easy to know the leak level.

I was slowly being poisoned by freon leaking into my apartment from the ac unit which was inside my unit. I was becoming sick and kept smelling an odd chemical smell. Despite mechanics coming and saying it was okay and I was delusional, I purchased this device and immediately found the leak myself!!! See video! Then the property had a professional AC person come and test it and their expensive freon leak device found it just like mine! The AC professional said this meter was a very good device!!! It saved my life! The high sensitivity setting is really nice and it’s easy to use. God bless your company. I could even measure the freon as it crept along the floor of my bedroom to go out the open window which allowed me to make the decision to stay at a hotel until the leak was fixed. Health and safety 1st!!! 5 stars all around!

Used this detector on a few service calls now and it’s already paid for itself. Super easy to use and picks up even small leaks fast. The sensitivity is solid and saves a ton of troubleshooting time. Battery life is great — I can get through a full day without recharging. Definitely a handy tool to keep in the van for quick diagnostics.

Facil de usar, ayuda a detectar fuga durante la instalacion de equipos nuevos y usados ya instalados

I’m a hvac technician actively in the field. This tool so far has been worth the $$$ I spent to purchase it. The controls are simple to use and the display is bright and big, easy to see in a dark attic. My only complaint would be that the instructions for this device are the same instructions for all the devices in the same series of tools. I sometimes will get a symbol on my display but I don’t know exactly what it means. The user manual speaks nothing of this symbol. I soon learned that other models of this leak detector uses the exact same user manual.

Lo estado ocupando en Refrigeracion y a/c. Asta ahora cumple muy bien la detección de fuga especialmente la micro fuga.

Worked great.
