Wey-TEK Refrigerant Charging Scale & Optional Charging Module

Proven Accuracy and Value - Now With a 220 Lb. Capacity

The Wey-TEK Refrigerant Charging Scale continues to set new standards in affordability and accuracy for refrigerant scales, enabling you to easily weigh and charge from the same large platform. Now it offers even more value, with a higher weight capacity-220 lbs., twice that of many other scales at a competitive price.

Wey-TEK is very easy to use. Its high-accuracy load cell gives the correct reading every time (no matter where the cylinder is on the weighing platform), and you can read its large LCD display at a distance, even in direct sunlight.

 Wey-TEK offers the highest accuracy available: 0.25 oz. (10 gm.). It also handles a wide range of standard cylinders. This precision and versatility makes it ideal for charging or recovery of all refrigerants. Use the optional charging module to turn your Wey-TEK into an automatic charging station.

 Wey-TEK comes with a plastic carrying case for even greater protection and convenience.

A high-performance necessity for your service kit, Wey-TEK makes an excellent companion to the D-TEK Select or TEK-Mate Refrigerant Leak Detectors.
