Wey-TEK HD Wireless™ Refrigerant Charging Scale


Building on the proven performance of Wey-TEK, the Wey-TEK HD Wireless Refrigerant Charging Scale sets a new standard for versatility, durability and accuracy in a 250 lb. capacity scale.

Wey-TEK HD Wireless uses Bluetooth® wireless technology to reliably display real-time measurements on your smartphone or tablet using the free app (on the App Store℠ or on Google Play™)*.  If you prefer a dedicated handpiece, an optional wireless handpiece is available with a full color display. 

The app and handpiece both feature an innovative alarm mode which alarms when approaching a programmed target refrigerant charge amount, then alarms again when the target charge is reached.  This allows you to walk away and multitask on the job site.

Recent changes to EPA standards require logging of refrigerant.  The Wey-TEK HD app includes a convenient job log feature to quickly and easily save and email spreadsheets for refrigerant tracking.

For customers who cannot access Google Play, you can download the Wey-TEK HD Android app here.
