NRS2A – Navtek Smart Refrigerant Scale – Precision Weight-Based Charging and Recovery for HVAC&R Professionals

Precise Weight-Based Refrigerant Charging and Recovery

The Navtek NRS2A Smart Refrigerant Scale delivers precision and convenience for refrigerant charging and recovery tasks. With 0.05% full-scale accuracy and 0.2 oz resolution, it provides the precise weight measurements needed to charge systems correctly and track refrigerant recovery accurately — reducing the risk of overcharging and ensuring compliant refrigerant management.

myNAVAC™ App Integration and NSV1 Smart Valve Connectivity

The NRS2A connects wirelessly to the myNAVAC™ App via Bluetooth, enabling real-time weight monitoring, data logging, and target-weight charging directly from a smartphone. When paired with the NSV1 Smart Refrigerant Valve, the NRS2A enables fully automated refrigerant charging — the valve opens and closes automatically based on the target charge weight set in the app, for a more accurate and streamlined workflow.

Lightweight Magnesium Alloy Platform

The NRS2A is built with a magnesium alloy weighing platform — significantly lighter than comparable steel-platform scales, while maintaining excellent strength and durability. At just 3.3 lbs (1.49 kg), the NRS2A is noticeably lighter than competing products, making it easy to carry to and from the job site without adding unnecessary weight to your kit.

Wireless Handheld Remote Controller Included

The NRS2A comes with a wireless handheld remote controller, allowing technicians to read and control the scale from a distance without needing to use a smartphone. The remote provides a clear display and dedicated controls for tare, unit selection, and other key functions — a practical tool for working in confined spaces or when hands-free operation is needed.

Impact-Resistant Design with Integrated Handle

The NRS2A features an impact-resistant body designed to withstand the knocks and drops of daily job site use. The integrated handle makes the scale easy to carry between locations, and the rubberised weighing platform surface prevents cylinders from sliding during use.

Long Battery Life with Standard Batteries

The NRS2A scale runs on 4 x AA batteries for up to 150 hours of typical use, while the wireless handheld remote runs on 4 x AAA batteries for up to 65 hours (backlight off). Standard batteries mean easy, cost-effective replacement in the field — no proprietary cells or charging cables required. Auto power-off further conserves battery life between uses.

100kg Capacity with 100 ft Bluetooth Range

The NRS2A handles a maximum load of 220 lbs (100 kg), covering the full range of refrigerant cylinder sizes used in residential and commercial HVAC applications. The 100 ft (30 m) Bluetooth range gives technicians the freedom to monitor and control the scale wirelessly from across the job site.
