Top 10 Best Refrigerant Charging Scales

HVAC and refrigeration technicians rely on refrigerant charging scales on a daily basis.  Charging scales are not only used when adding refrigerant to HVAC and refrigeration systems but also for removing refrigerant.  Having a high quality, reliable refrigerant scale is essential for ensuring that systems are safely charged with proper refrigerant amounts.

In today's market, calculated refrigerant charges are becoming the norm.  In order to properly charge new systems with refrigerant, technicians must have a refrigerant charging scale on hand.  These scales make it a lot easier to calculate how much refrigerant (liquid or gas substance) should be placed in or removed from the unit.

A refrigerant charging scale is an excellent tool for HVAC technicians; it helps get the job done effectively. 

However, refrigeration scales come in different qualities with different brand names, and only a high-quality scale will provide an accurate reading. The precise reading will make the unit perform at an optimum level without a chance for error, and help you bill the client accurately.

This article will discuss the features, specifications, pros, and cons of the 10 high-end refrigerant charging scales. Let’s get on with it.

Refrigerant Charging Scale Buying Guide

Before you decide which refrigerant scale to buy to fill up your HVAC equipment, you must know what you are getting into. The HVAC market is a vast place, consists of different brands and models. You must know the factors you ought to consider before jumping into the market and decide.

To make it easy for you, we have conjured a buying guide below, which will help you decide according to your needs.

Weight Limit:

The refrigerant scale's primary purpose is to weight the refrigerant. So, it is a must that your scale has enough capacity to measure refrigerants of all mainstream sizes. Most scales offer a maximum capacity of up to 220 lbs. (equivalent to 100 kgs).

However, some scales offer a capacity of up to 330 lbs. with a little bit addition of price. If you are in the HVAC service field, it is best that you buy the one with the maximum capacity to deal with every kind of customer. But if you are buying for home use, you should go for the one you need.

Size and Form:

The size is the most underestimated factor, people don't pay enough attention to it, but it's vital, especially for the dealers. Since the refrigerants are usually used on a remote job site, they need to be small, lightweight, and portable.

The compact scales are often lightweight and are easy to carry on every job spot. It fits easily in your tool kit. It is best if the refrigerant scale has a case; the case prevents damage.


Suppose you are weighing the refrigerant of up to 300 lbs. Is your scale durable enough to handle that weight?

If you are using the scale to measure heavy quantities, you must buy the one with a sturdy, durable body so it can stand the weight.

Precision and Accuracy

Initially, every seller will tell you that the refrigerant scale you are buying is 100% accurate. However, it would not be true in all cases. You need to be sure that the scale you are buying is accurate; it is one of the first things you ought to check.

However, most scales indeed come with built-in errors, meaning the mistakes which cannot be cured and occur occasionally, but less chance of error indicates a better scale.

On the other hand, the precision is your personal choice. If you want to find out 100th of a pound, you can check if the scale is capable of measuring it precisely. But in most cases, you don't need that. Charging can be done with the 10th of a pound. Though while recovery, sometimes precision comes in handy.

Display and Reading

The refrigerant scale shows reading through screens, at least the modern ones. Going for wireless or wired one is solely your decision; it depends on what level of convenience you are looking for.

However, the digital screen matters a lot. For the use in sunlight, the screen with high-intensity illumination will perform excellently. If you work in the nighttime, you should opt for the one with backlit LCD.

The excellent quality scale shows reading in three different modes: oz, kgs, and lbs. The three modes work effectively for all users and help you get the precise weight. If you are involved in the HVAC service, you should demand the scale with three modes to satisfy your clients.

Most of the time, the scale shows reading only once, but some scales come with the storage capacity that can allow you to check previous recordings of weight. Although it is a unique and helpful feature, opting for it depends on your use.

Battery Charging

Modern refrigerant scales run on batteries. You should change your battery regularly. The concern here is to check the battery regularly for moisture, debris, corrosion, etc. Some scales show the battery bars on the LCD – you can opt for them if you need – with this, you would be notified before the battery runs out.

In some scales, the auto-off feature is an excellent provision to save the battery from being wasted.


The platform is among the most important things to look for in the refrigerant scale. Small platforms lead to dissatisfaction because they can't hold the size of large refrigerants. Refrigerants come in all sizes, shapes, and weights, so it is best that you choose the scale with the largest platform possible.

On the other hand, the platform has to be of rugged and sturdy material. The slippery platform might create a disruption during the measurement of charging, which can lead to an inaccurate reading.

Additional Features

To stay in the competitive market, brand sellers add multiple additional features to increase users' ease and convenience. One of the extra features is mobile app connectivity or Bluetooth/Wi-Fi connectivity.

These features are added just to highlight the brand in the market and create flashing advertising, but honestly, these features do worth your money and consideration. After all, they make it easier to use the machine.

Another additional feature is the battery. Some models include the battery, and some do not. Although a battery doesn't cost much, it sure provides excellent customer satisfaction.

Moreover, the carrying case is an additional feature, but it increases the efficiency of the machine. It protects the machine from damage, makes it easy to carry, and, eventually, expands the scale's lifespan.

Although you might have to pay a bit more price for these features, they add significant value to your money.


Price is the most crucial factor. The affordability is always essential, whatever you are buying. Similar to most of the HVAC equipment, the refrigerant has a standard price range. The right refrigerant scale starts from $150 – going high with specifications – up to $200 or $300.

Remember, when the price increases, the quality increases too. But of course, you must set a price range and shop within it.


If you are looking for a refrigerant scale to weight the refrigerant for your garage or bedroom, you can either call an HVAC technician or do the job yourself. To do the job yourself, you ought to have a refrigerant charging scale precisely according to your need. However, the process gets complicated a bit if you are a technician.

If you are involved in the service field of AC or other HVAC systems, you must need a refrigerant charging or recovery scale, and you must consider some crucial factors before buying the refrigerant scale (listed in the buying guide). Going for the right kind of refrigerant scale is essential. Measuring the correct weight and recording accurate reading is crucial, especially when serving a customer. One wrong move can stain your service and cost the customer.

However, there are multiple good options – listed above – from which you can choose. These models are all from respectable and well-reputed brands, and some of them even offer a warranty.

To make it easy for you, we have added their features, specifications, pros, cons, and details one might require to buy a refrigerant scale. Additionally, the buying guide will help you sort out your requirements so you can buy according to them and provide an accurate value to your money.
