Part I - Product Review: Elitech LMC-300A HVAC Refrigerant Charging Scale | From

Welcome to Refrigerant HQ for another review article. Today we would like to review the Elitech LMC-300A HVAC Refrigerant Charging Scale. It’s one of the most recommended refrigerant scales on Amazon since it has a weight capacity (measuring range) of up to 330 pounds. It also provides accurate weight readings, which makes it a great tool to include in your list of tools.

Having the right tools for the job as an HVAC technician can make a huge difference. For instance, charging a lower amount of refrigerant than required can cause overheating of the cooling system. The air coming out of the system becomes hotter instead of being cool. On the other hand, adding a higher amount can create high pressure. Eventually, you’ll have a system that is no longer energy efficient and costly to maintain.

Apart from being accurate, what other qualities does the Elitech LMC-300A offer?

We researched and compared this product to many others in its category.  If you want to learn the ins and outs of this product, this article offers an in-depth analysis of what you will get from this product.

Elitech HVAC LMC-300


When it comes to producing HVAC tools, I believe Elitech stands out amongst most brands in the market. Some of the products we’ve reviewed on Refrigerant HQ include Elitech ILD-200 Infrared Leak Detector and the Elitech IR-200 Dual Sensor Leak Detector.

The company has been in business since 1996 and has a wide range of high-quality products in its online store. The brand’s headquarters are in San Jose, California. They also have branches in the United Kingdom, Brazil, Belgium, Canada, and in about 170 countries around the globe. Apart from different refrigerant scale models, other equipment they manufacture include data loggers, HVAC tools, air quality monitors, and software for real-time configurations and setups.

We noticed that some brands typically buy some of the parts they manufacture to include in their products. So if you find a product with an Elitech tag but comes from a different brand, the chances are that some of its parts come from Elitech.

Most of their products come with a user manual and a warranty. You should expect to receive exceptional support from their trained engineers and technicians if you have any issues with their product. On top of that, they also have a Facebook HVACR Technician Community where they provide information regarding their products, including tutorials. If you have any problems with the product you purchased, you can return them within 30 days of purchase. You’ll get a replacement immediately.
