BlendJunk

BlendJunk is the gas blending app for technical divers and fill stations. Connect your oxygen analyzer wirelessly via Bluetooth and let the app do the rest.

ANALYZE Connect your OxyJunk, Divesoft or DNA analyzer via BLE. The app instantly shows your O₂ and He values and automatically calculates the MOD based on your ppO₂ limit.

BLEND Enter your start and target pressure, choose your target mix and BlendJunk calculates exactly how much of each gas to add. Including fill order and top-up gas selection.

PRINT Print a professional cylinder label with all gas data directly to your Brother label printer. Scan a cylinder with NFC or QR and the cylinder ID appears automatically on your label.

WIRELESS Connect your wireless pressure sensor (WLB-PT) to automatically read cylinder pressure. No more manual input needed.
