CDI 5450 Hot Tap

Price Range: $1,145 – $2,695

The CDI 5450 is a modified version of the 5400 model that allows installation under pressure. It incorporates two valves through which the probes pass and a muffler that collects chips from the drilling process. It takes an equal amount of installation time as our standard meters and requires no shutdown of the compressed-air system.




  • No system shutdown required
  • Installs in minutes
  • Weather resistant and surge protected
  • Milliamp output
  • Pulse output convertible to threshold output
  • User-configurable scaling, filtering and units of measure
  • Optional wired or wireless output for networking
  • Housing rotates to suit vertical or horizontal installation

The installation of the 5450 is quick, easy and safe, if done with adequate preparation and with care. A solid footing and face protection are essential. Once installed, the meter provides the same features as our 5400-series meters.
