PB Motor Tech BMT 220lb Electronic Refrigerant Charging Scale — 9x9in Aluminum Platform, ±0.05% Accuracy

PB Motor Tech BMT 220LBS Electronic Refrigerant Charging Scale is a rugged, portable digital scale built to accurately weigh refrigerant recovery tanks up to 100 kg for HVAC charging and service.

This compact freon scale combines a heavy-duty aluminum platform with rubber coating, a large backlit LCD, and a sturdy carrying case so technicians can measure refrigerant on-site with confidence. It reads in pounds, kilograms or ounces, offers high accuracy, and includes an auto-zero function to simplify tank tare and flow measurements. The design omits auto-shutoff so the display stays visible throughout long procedures.

How accurate is this scale for refrigerant charging?

The PB Motor Tech BMT scale provides precise weight readings with an accuracy up to ±0.05%, suitable for most HVAC service and refrigerant charging tasks. Its large LCD and three selectable units make monitoring straightforward at a glance.

• Accuracy: ≤ ±0.05% of reading
• Capacity: 220 lb / 100 kg
• Units: Lbs, Kgs, Oz selectable
• Clear backlit LCD for easy reading in low light

What features make it durable and portable for field use?

This scale is built for jobsite conditions: an aluminum body resists corrosion while a rubber-coated platform absorbs shocks and resists spills. A fitted heavy-duty carry case protects the instrument in transit and keeps accessories organized.

• Aluminum construction with rubber coating for impact resistance
• Slip-resistant 9" x 9" platform holds various tank sizes securely
• Included hard carry case for transport and storage
• Water-resistant surface helps protect against light spills and condensation

How is it powered and operated during long service calls?

The unit runs on a single 9V battery (not included) and deliberately lacks an auto-shutoff so readings remain visible until you choose to power down. An auto-zero (tare) button helps you set the valve or tank baseline quickly before charging.

• Battery type: 9V (user-supplied)
• No auto-shutoff — continuous display for uninterrupted monitoring
• Auto-zero/tare function for accurate start-point measurement
• Simple keypad for unit conversion and tare/reset

Will it work with all refrigerant tanks and recovery systems?

The 9" x 9" platform and high capacity make this scale compatible with most refrigerant cylinders and recovery tanks used in HVAC work. Its universal weighing design supports any refrigerant type since it measures weight rather than chemical composition.

• Platform size fits common recovery tanks and refrigerant cylinders
• Works independently of refrigerant type — measures weight only
• Slip-resistant surface stabilizes tanks during charging or recovery
• Three-unit display eases cross-checking and documentation

Who is this for: Field HVAC technicians, refrigeration service professionals, and maintenance teams who need a reliable, portable scale for refrigerant handling. It suits anyone who prioritizes rugged construction, continuous display during procedures, and quick, accurate weight readings when charging or recovering refrigerant. If you prefer an automatic power-save feature, consider other models; otherwise this model delivers straightforward, job-ready performance with a protective case for transport.
