Elitech Refrigerant Scale 330 lb

How to use it

The included solenoid valve is the standout feature: once the programmed target amount is reached, it automatically pauses refrigerant flow. That makes the LMC-300A more than a platform for watching a display, it is designed to control the charging step as well, which can be useful when servicing larger HVAC systems or other equipment that needs a measured refrigerant charge.

In a typical service workflow, you can place the refrigerant cylinder on the scale, choose a display unit, and use the programmable charge control to stop at the target. The backlit LCD helps make readings easier to see, while the three modes—kg, lb, and oz—let you work in the unit that suits your process. What matters more on a busy job: just seeing the weight change, or having the valve stop the charge at the set amount?

The scale has a stated 330 lb capacity and an overweight alarm. Its listed accuracy is ±0.05% of reading +25 g. The description does not give platform dimensions, battery details, or a charging increment, so those specifics may matter if you need to match it to a particular workspace or procedure.

Pros

• Automatic charge control: The included electronic solenoid valve pauses flow when the programmed target is reached, reducing the need to stop the charge manually at that point.
• Higher load capacity: At 330 lb, it is described as an upgrade from the LMC-300 and is aimed at larger systems and heavier-duty service work.
• Useful handling details: A backlit LCD, three weight modes, an overweight alarm, and auto power-off address visibility, load awareness, and battery use.
• Built for demanding environments: The body is aluminum, with impact-resistant rubber feet and reinforced protective corners.

One limitation is that the listing does not specify the platform’s dimensions or how the scale is powered. If your setup has tight space or a required battery arrangement, that missing information may affect the fit. The stated accuracy also includes a +25 g term, so it is worth considering the full rating rather than focusing only on the percentage. Without having tried it, the listed features point to a tool aimed at controlled charging rather than basic weight checks alone.

When it makes sense

It’s a great fit if you regularly service HVAC systems or other equipment where a higher-capacity scale and a controlled charge are useful. For example, during a refrigerant service, the set target and automatic valve pause can make the charging stage more straightforward than relying on a scale that only displays weight and leaves the shutoff entirely to the operator. The listed applications also include automotive systems, construction machinery, and heavy-duty mining equipment.

It’s not for you if you only need a simple scale for occasional, lower-capacity work, or if your buying decision depends on dimensions, power details, or a specified charging increment that are not provided here. Compared with a more basic scale, the LMC-300A’s main reason to choose it is its valve-based auto control and 330 lb capacity, if you do not need either, those features may not add much to your workflow. The stated capacity and missing fit details are the practical checks to weigh before choosing it.
