Part II - Product Review: Elitech LMC-300A HVAC Refrigerant Charging Scale | From refrigeranthq.com

Operating the LMC 300A

Connect the solenoid valve to the scale via the DIN connector and the refrigerant hoses. Turn on the scale on by pressing the power button on the remote control, then wait for it to flash from 0000 to 9999 to start functioning. Then zero it out. You can test its accuracy to avoid errors before starting the charging or recovery process. Inaccuracy can be costly, especially when charging sensitive HVAC systems.

Place the refrigerant cylinder on the scale and if you want to charge, press the ‘charge’ button on the remote control, insert the amount you want to install in the unit, and press enter. Press the recover button if you want to recover the refrigerant and enter the amount you want to install.

Once the charge or recovery process is complete, the charge valve will shut off automatically. You will also hear a loud alarm beep, which you turn off by pressing any button on the remote.

Pros

When comparing the Elitech LMC 300A to other products, we found that this unit benefits the user in so many ways. The product has a measuring range of about 330 pounds. You can use it in cases where you will recover or charge high amounts of refrigerants. Besides this, the remote can display three weight metrics, making it easy to convert the values.

I am sure that this scale is durable. The platform has non-slip rubber material, preventing recovery tanks from slipping during the refrigerant recovery or charge process. On top of this, it can also operate in temperatures as low as -10 degrees Celsius to 50 degrees Celsius.

Further, the scale is compact and portable. It has a storage compartment underneath to store the remote control. We found it safe and convenient since it has straps to prevent it from falling. By the way, the remote has a small collapsible handle to help you hang the scale to a wall.

The refrigerant scale is also accurate. Compared to other products from the brand, this unit has an accuracy range of about +/- 0.05% rdg +25g. You are sure that you won’t overcharge or recover less or more than you intend.

If you find yourself recovering or charging an HVAC system in a dark area, the remote control has a backlight to help you see in the darkness. The expansive display also ensures that it’s easy to use, even in areas where there’s direct sunlight.

Finally, the solenoid valve or charge valve is convenient and safe since it uses direct current from the remote controller. It also relies on the remote control function to operate.

Other benefits:

• The battery life is around 35 hours
• Alarm beeps allow you to know when the charging or recovery stops

Cons

The LMC 300A refrigerant scale has its weaknesses too. I compared it to other products, and we found some limitations we think might be an issue for some users. For instance, the warranty is too short. Offering a one-year warranty for a product of its price might not be appropriate for specific buyers. Therefore, adding a year or so might help.

Another issue is that the remote control connects to the scale via a cord. I found this a bit old school, especially since some scales connect via Bluetooth, which is wireless. Some of the products from Elitech, actually, have smart capabilities. If included in this product, it would contribute to convenience and effectiveness.

I also don’t like that you have to replace the batteries. Having to buy batteries can be a bit cumbersome, especially if they don’t have a charge.

Conclusion

We appreciate the time you took to read this article from the start to the end. So, is Elitech LMC-300A worth the money? From the above analysis of this product, we can all agree that it has its strengths and pitfalls. However, this is a product you can rely on for years.

We would recommend it to HVAC technicians who love a product they can use when you need to recover or charge large amounts of refrigerants. It is also easy to know how much refrigerant to recover since it’s accurate and how much you will need to charge clients.
