Technical Datasheet: JAKO Dual Mano-Thermometer

Product Overview

The PN4204BD10 is an industrial-grade dual-indication instrument (Mano-Thermometer / Thermomanometer) manufactured by JAKO Messtechnik. This specialized mechanical gauge combines static fluid pressure and media temperature readings onto a single dial face. It is primarily engineered for closed heating circuits, boiler tracking, and commercial HVAC infrastructure.
