NRS3i01 – Navtek Wireless Bluetooth Electronic Refrigerant Scale – Precise Refrigerant Charging, Hands-Free

Charge Smarter with Bluetooth Wireless Technology

The Navtek NRS3i01 is a professional-grade Bluetooth wireless electronic refrigerant scale designed to make refrigerant charging more precise, more efficient, and more convenient. By wirelessly connecting the scale to the included handheld device, you can monitor the charge in real time without being tethered to the scale — freeing you up to perform other tasks while charging is underway.

Real-Time Weight Monitoring with Smart Alerts

As refrigerant is charged into the system, weight data is transmitted in real time to the handheld controller. When the charge gets within 2 oz of your target setting, the handheld device buzzes to alert you — and alerts again when the exact target is reached. This smart alert system helps prevent overcharging and improves accuracy on every job.

High Precision — 0.05% Accuracy, 0.2 oz Resolution

With a 0.05% accuracy rating and 0.2 oz resolution, the NRS3i01 delivers the precision required for professional refrigerant charging. Whether you’re topping up a small split system or charging a large commercial unit, the NRS3i01 ensures you hit the target every time.

Large 220 lb Capacity

The NRS3i01 handles refrigerant cylinders up to 220 lbs — covering the full range of cylinder sizes used in residential and commercial HVAC work.

Magnesium Alloy Weighing Pan

The large weighing platform features a magnesium alloy pan — a material chosen for its combination of strength and light weight. This makes the NRS3i01 easier to carry to the job site without sacrificing the durability needed for daily professional use.

Large Backlit Display on Handheld Controller

The handheld controller features a large backlit display that’s easy to read in all lighting conditions — from bright outdoor environments to dimly lit plant rooms. The intuitive keypad layout makes setting target weights quick and straightforward.

Ergonomic One-Piece Portable Design

The integrated handle and one-piece construction make the NRS3i01 easy to pick up and carry between jobs. At just 3.3 lbs, it adds minimal weight to your kit while delivering maximum functionality on site.

Battery Powered for Cord-Free Operation

Powered by 4 x AA batteries (scale) and 4 x AAA batteries (handheld), the NRS3i01 operates completely cord-free — giving you the flexibility to work anywhere without needing a power outlet.

The Professional Choice for Accurate Refrigerant Charging

Don’t leave refrigerant charging to guesswork. The Navtek NRS3i01 gives you the precision, convenience, and wireless freedom to charge systems accurately and efficiently — every single time.
