Digivac/Signum Thermometer and clamp probe  and  New Ultra Fast Probe

Digivac has now acquired manufacturing rights to the industry-favorite Signum neon sign processing clamp-probe thermometer. The inventor decided that twenty years of manufacturing this legend was enough and Digivac has made an offer that will help him enjoy his retirement.
This thermometer and its clamp-on probe will now combine the Digivac reputation for manufacturing and timely delivery, while retaining the speed and ruggedness of Bill's original, brilliant, design.
Ultra Fast Probe
The new ultra fast probe is a great leap forward in Neon sign processing. For the first time, this probe measures the actual temperature of the glass without the interference of any rubber or metal parts. 

Ultra Fast probes typically show a temperature 50 degrees C higher than traditional clamp type probes. 

Additionally, the actual thermocouple is user-replaceable.

Neon Sign Vacuum and Filling gauges

Start with the bad news: you need two gauges! Moreover, they should not have mercury and they should be rugged enough to survive an occasional drop to the floor. They should also be resistant to flashback damage during bombarding. If you buy both gauges at the same time, we will give a generous discount.

First, you need a micron-type gauge to monitor evacuation.
Digivac thermocouple digital vacuum gauges are admirably suited for the purpose.
Secondly, you need a torr-type gauge to monitor backfill with neon, argon, or whatever.
A Digivac transducer-type gauge is recommended.

Widely used micron gauges are:
Digivac 100tc/2a/199.9           with Frederics 2a tube
Digivac 100tc/2a/199.9/batt    as above, but battery operated
Digivac 45/2a/199.9/batt         Frederics 2a, battery, in slant case

The Model 100tc is also available for the Hasting DV-6 tube.
Battery operated gauges are not connected to ground. As such, they are far less suceptible to damage from flashback while bombarding than line-powered gauges. On the other hand, battery replacement is a nuisance.

Generally, if the gauge is isolated from the manifold with a stopcock, it will be adequately protected as long as the operator remembers to close it before bombarding. Since Digivac gauges have socketed components, they can usually be easily repaired if a problem occurs bombarding. If within a one year period, the gauge will be fixed under warranty at no charge.

Digivac Torr / Filling Gauges:

Digivac Model 100 Led/760/199.9/sw Line powered, Led display with range sw
Digivac Model 100 / 760/batt Battery powered, LCD Display

Filling gauges are usually not installed as close to the manifold as micron gauges, so more users prefer line power.
