The Teledyne Hastings vacuum gauge tube is known for it's reliability, repeatability, durability, accessibility. And the proof is on the inside.
Because Hastings employs proprietary fixturing technology that eliminates physical handling of components, the inside structure of our vacuum tubes is unsurpassed.
Our stringent quality control demands a tight band of acceptance for output verification and all tubes are 100% leak tested using a helium-based mass spectrometer.
An overview of what you might find in our competitor's tubes.
Potting compound, stressed wires and contaminants are clearly visible.
Note inconsistent vacuum solder joint.
Poor TC fabrication requires external matching resistor.
Note inconsistency of solder in vacuum joint.
We measured the mV output of a sample of gauge tubes. This table shows the spread in output of each manufacturer in high vacuum.
We tested each of the three populations of tubes to "Method 214 of Mil-Std-202, Test Condition IG." This table summarizes the results.
You wanted it there yesterday. Any delay could cost you. You need a proven reliable supply chain that can deliver a vacuum gauge tube, where you need it, when you need it.

All vacuum gauge tubes are not created equal. We know. We looked inside.

Because Hastings employs proprietary fixturing technology that eliminates physical handling of components, the inside structure of our vacuum tubes is unsurpassed.

Using a clean flame and resistance welding, we create a precision junction between thermocouple wires. We attach the thermocouples to electrical vacuum feed through pins using very sophisticated precision weld technology. Every installed thermocouple is resistance tested to precise specifications.
