Thermowell Bar stock


Digiqual threaded thermowells are utilized when pressure, high velocity and corrosive process media exist. This serves to isolate and protect the sensing instrument, and permits removal of a sensing instrument without shutting down the process. A perfect solution for protecting the process and extending product service life.
Key Features:

  • Straight, Stepped or Tapered designs
  • One piece bar stock
  • Wide selection of sizes, material and dimensions
  • Stamped with date code, material and heat numbers
  • Specifications:

  • Process connection: 1/2″, 3/4″ and 1″ NPT
  • Bore size: .260″, .385″

Portable Thermocouple

We manufacture a wide range of hand held sensors for various applications such as food, beverage and cold storage facilities in standard thermocouple types K, J & T with specials available on request. We can supply them as RTD’s such as PT100 & PT1000 and in some forms of thermistors.
A selection of insertion, penetration and surface hand held sensors are available from stock for quick delivery.
