Design
The Kalibr RTA is a rebuildable atomizer designed by Kaser Mods. Featuring a 23 mm diameter and a 30 mm height, it offers a 4.5 ml capacity.
Manufactured mainly from stainless steel, it features a top-filling system with a quarter-turn opening. The Kalibr is supplied with two interchangeable chimneys, one dome-shaped and one stepped, allowing users to adjust the flavour output depending on the e-liquid used.


Build deck
Access to the Kalibr 23.30 build deck is achieved via base rotation, offering three distinct positions. One position keeps the liquid inlets open, another disengages the deck, while the last fully closes the liquid flow to facilitate refilling.
The single-coil deck, equipped with two opposite posts, features a central groove for easy coil positioning, along with two dedicated cotton slots for accurate and simplified wicking.
Airflow and customisation
The Kalibr’s airflow system is fully adjustable using interchangeable airflow pins measuring 3.5 mm, 3.0 mm, 2.8 mm, 2.5 mm, 2.0 mm, 1.8 mm, 1.5 mm, and 1.2 mm, making it suitable for MTL to RDL vaping styles.
An additional airflow adjustment is provided via a PEEK component featuring three separate air inlets, allowing further fine-tuning of the draw. In terms of customisation, the Kalibr is supplied with two chimneys: one made entirely of PCTG, and an other combining stainless steel and PCTG, enabling users to customise the atomizer’s appearance.
