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.

FLEXIBLE
No analyzer at hand? Enter your values manually and use BlendJunk as a standalone blend calculator.
