Elitech LMC-310A Wireless Refrigerant Scale HVAC Freon Weighing Scale 330lbs Remote Control with Auto Open/Stop Charging Valve

Everything about this scale is right.The packaging, the carrying case with shoulder strap, the bay for the display at the bottom of the scale, the valve to stop the charge or evacuation automatically, the accurate and stable readings, the intuitive control, the ruggedness, are all well thought out and make using the scale easy.I wanted the wired model with 5 AAA batteries, to avoid having two sets of batteries (one for the scale, another one for the display). I did not want the blue-tooth model, or rechargeable models. Too many batteries to remember to recharge.If I were to object to something, it would be the stiffness of the control coiled wire, and the lack of a clearly visible flow direction on the valve body.I am very pleased with the scale and I will recommend to anyone looking for a charging scale with the specs this one has.

This product including the cover bag easy to carry on and function is good it got everything i needGood choice and make job more easier

Works great! Used in temps below -5f works flawlessly. The auto off is a great feature. Highly recommend.

Pros: This scale works well, especially for DIY'ers and occasional use by professionals. The unit is of solid construction and should take some abuse without causing damage. The price is half that of other well known brands that offer the same features. The automatic charging valve is gimmicky but works as instructed.Cons: The app is finicky and needs polishing. Works fine once connected but sometimes requires multiple attempts to connect. The unit has an auto shutoff function which became annoying while charging. I went to observe the indoor air handler while slowly charging 410a into an empty system. By the time I returned the unit had shut off (I assume bc my phone was out of Bluetooth range). After powering back on, the unit reset to zero so I had no idea how much has entered the unit. Good thing I calculated tare and wrote down the remaining refrigerant with each use. Last, the battery compartment seems like it could use better water intrusion protection.

Carry case is well made, The scale Looks rugged, Easy to set up - Batteries Included!

As stated, I have wanted one of these since I started doing A/C. This one looks, feels, and works great! I have always had to rely on pressures alone to determine if I had the right amount of gas. The handheld meter lets me know when I put the right amount in. That wasn't the most accurate way to do it.

Makes adding Freon so easy. Get it with the optional on off solenoid. Just set it up,enter how much weight to add hit start and don't worry about anything.

This scale appears to be very precise and seems very durable. It worked well to refill my Pioneer mini split to the factory charge level. The reading is very precise, meaning it does not jump around at all, the weight reading is very stable. I can't comment on the accuracy, as I didn't have any calibrated weights to measure it against, but my mini split is operating as expected after the refill, so it's definitely accurate enough for this application.
