Best refrigerant charging scale for residential HVAC and mini-splits

A good charging scale earns its space in the van twice: when you weigh refrigerant into a mini-split, and when the office can see exactly what went into that system. Buy for the readout you will actually use—not the biggest number on the box.

Choose Fieldpiece SR47 if your kit already runs on Job Link. Choose NAVAC NRS2i01 for a light scale with a separate handheld display. Yellow Jacket 68864 suits a YJACK VIEW workflow; CPS CC220EW suits a shop that wants tank-use records plus the option of a separate charging valve.

Quick picks: match the scale to your service kit

Your setup	Our pick	Why it fits
Job Link tools already in the bag	Fieldpiece SR47	Included wireless remote, Job Link readout and a 252 lb platform
Carrying the kit through a house or up to a condenser	NAVAC NRS2i01	A 3.3 lb scale with a Bluetooth handheld display and target-charge alerts
YJACK reports for the office	Yellow Jacket 68864	Phone/tablet readout with logged weights, elapsed time and email export
Tracking supply/recovery tanks across jobs	CPS CC220EW	Corded LCD or CPS Link, Tank Tracker records and an optional SVW valve

All four are scales, not manifolds or clamp meters. Keep the digital manifold guide beside this shortlist when building the charging kit.

Resolution is the size of the display step. Accuracy is the manufacturer’s weighing-error specification. Select the units you intend to use: SR47’s ounces-only mode steps by 0.3 oz, while its pounds-and-ounces mode steps by 0.25 oz. The CPS ounce/gram figures above are its published display settings, not exact unit conversions.

The Fieldpiece specifications, NAVAC specifications, Yellow Jacket specifications and CPS specification sheet supply the model-specific figures. CPS lists the scale’s A2L category on its product page.

Fieldpiece SR47: best for Job Link users

Why you’ll like it: Put the cylinder on the 13-inch platform and read the weight on the included remote or in Job Link. If you already use Fieldpiece’s app, the scale joins the measurements you are collecting instead of adding another app to the phone.

The remote has a magnetic mount and stores inside the scale. Fieldpiece rates the platform IP54 and the remote IP64, with typical alkaline battery life of 200 hours for the platform and 80 hours for the remote with its backlight off. The published wireless range is 1,000 feet line of sight; walls and equipment affect the working range.

Good to know: Use the Weight tab in Job Link to connect the scale and keep the refrigerant-use record with the call. Fieldpiece’s SR47 product and setup page covers the app, remote and unit settings.

NAVAC NRS2i01: best lightweight handheld setup

Why you’ll like it: NAVAC lists the scale at 3.3 lb, so it is an easy addition to a carry-in service kit. Its Bluetooth connection is between the weighing platform and the handheld display: you can keep the number where you can see it while the cylinder stays on the ground.

Set the target charge and the display buzzes when you are within 2 oz, then alerts you again when you reach the setting. That is a useful heads-up when you are watching both weight and the rest of the charging setup.

Good to know: The alert tells you to stop the flow; it does not close a refrigerant valve. The NRS2i01 maker page specifies the handheld connection and target alerts. Pick it for that straightforward workflow rather than expecting a phone-reporting app.

Yellow Jacket 68864: best for YJACK reports

Why you’ll like it: If the phone is already your service dashboard, the 68864 keeps the weight there too. YJACK VIEW displays gross weight, weight change and elapsed time, and lets you log and email the result. That makes it a neat fit for a tech who wants to send a charging record back to the office.

The platform is about 12 inches across, has an integrated handle and comes with a case. The scale uses a 9V battery; Yellow Jacket lists 40-plus hours of battery life.

Good to know: Your iOS or Android device is the readout, so bring it charged and ready to run YJACK VIEW. The 68864 specifications and app features cover the measurements and report export.

CPS CC220EW: best for tank-use records

Why you’ll like it: The CC220EW works with its corded LCD when you want a dedicated display, then adds CPS Link when you want job logs and tank records. The app stores customer/job data and tracks supply and recovery tanks, including refrigerant types and weights.

This is the pick for a shop that wants to organize refrigerant use across service calls. The separate SVW accessory adds an automatic-flow route to that setup; the scale alone provides weighing and alarms.

Good to know: Keep the accessory order separate from the scale order. The CC220EW sheet explicitly shows the SVW as purchased separately; the scale page explains CPS Link’s job and tank records.

Alarm or charging valve? Buy the control you need

An alarm is your cue to close the valve. A solenoid changes the flow itself. For most small-shop buying decisions, start by choosing a clear readout and a repeatable weighing routine; add automatic control when it fits the rest of the kit.

CPS’s SVW wireless solenoid has 1/4-inch SAE male ports and a published 500 psig maximum working pressure. It can be controlled through the CC220EW or CPS Link. Its published refrigerant list names common CFC, HFC and HCFC refrigerants and blends; it does not explicitly name R-32 or R-454B. For an A2L kit, get the accessory’s exact refrigerant approval before adding it. The scale’s A2L listing covers the scale.

Weigh the charge, then save the result

Use the appliance manufacturer’s charging instructions for the target amount. Set the scale on a firm, level surface, center the cylinder and keep hoses from tugging on the platform. Record the starting weight or use the scale’s tare/charge function, then watch the weight change as refrigerant leaves the cylinder.

Here is an illustrative job-note calculation, not a target charge for a particular system:

Recorded value	Example
Cylinder before charging	24.500 lb
Cylinder after charging	23.125 lb
Net weight removed from cylinder	1.375 lb = 22 oz

Keep hose handling and the appliance’s charging procedure consistent when recording the actual system charge. The scale measures weight; the service procedure determines where that refrigerant goes.

Capacity includes everything resting on the platform. A cylinder with a 16 lb tare and 25 lb of refrigerant puts 41 lb on the scale. Use gross weight to choose the platform capacity, and weight change to record the amount dispensed.

Tip: Finish the record before packing the scale: equipment ID, refrigerant, target, measured amount, technician and a photo of the final readout.

Complete the rest of the kit with our HVAC vacuum pumps, recovery machines and manifold gauges. The scale follows the refrigerant through the job; it does not replace any of those tools.

Put the charging record where the next tech will find it

Our software pick is Jobber for the charge record: put the measured amount and its supporting report beside the job, then hand the customer the useful summary.

In Jobber, add the refrigerant type, target and measured amount to a job note, then attach the readout photo or app report. Jobber’s notes and attachments work across jobs, quotes and invoices, with linking options for related records. Fieldpiece Job Link is the tool app; Jobber is the job record. Save or attach the result between them.

HCP alternative: use a private job note for the technician’s charging details. Select the relevant photos or documents when sending the customer’s invoice. Private notes stay internal, so put the customer-facing summary in the material you send.

For a repeatable install record, build the field list from our Jobber vs HCP job forms guide. Give the next technician a useful number and the equipment it belongs to—not a mystery photo in a camera roll.
