Digitry’s GB1 is a temperature controller that couples flexibility of programming with ease of operation. In addition to its use for annealing glass, the GB1 is a favorite of artists doing pâte de verre, lost wax casting, slumping, fusing, kilncasting, ceramics, crystalline glazing etc.
Ramps and soaks can occur in any combination. Each profile can have 15 steps of up to 99 hours each, allowing a total time of over 8 weeks. Plus, the GB1 can store 10 distinct profiles that can be instantly retrieved. For longer or more complex annealing, profiles can be linked.
The GB1 is the third generation of programmable temperature controllers designed and manufactured by Digitry since 1981. It incorporates the proven features of Digitry’s internationally bestselling GB4 — simplicity, reliability and advanced digital electronics — into a unit designed for glass and ceramic artists who need sophisticated control of a single annealing oven, kiln, lehr or furnace. Simply key in the points of your profiles and let Digitry do the rest!
Features and Benefits
Up to 15 set points for each of 10 separate temperature profiles gives you a nearly limitless number of temperature profiles with automatic calculation and control of ramps between set points.
Automated control eliminates time-consuming and awkward manual temperature adjustments while achieving smooth ramping.
Simple programming makes it easy to specify up to 99 hours per step, giving a total time of approximately 8 weeks. You can link several schedules to extend the control period.
Retains all temperature profiles — even without power.
Automated control lets you set your own schedule — no need to be on-site for set point changes. Fire your kiln during lower-cost, offpeak energy periods.
Temperature and ramping accuracy let you expand your product range, increase your productivity and enhance your creativity.
The auto-hold feature ensures that your preset temperature is reached.
Delayed start allows automatic preheating so that your oven is ready when you are.
Skip-step capability and keypad-initiated soak provide extra control for special techniques such as kiln forming and fusing.
Intelligent recovery protects your work from power failures. After an outage, the controller automatically decides how best to proceed.
Built-in warnings signal thermocouple burn-out and other malfunctions. You can connect an external alarm, such as a light, bell or phone dialer, for extra protection.
The large LED display clearly indicates program step, remaining step time, temperature, mode and operation.
Furnace versions are available for both gas and electric furnaces.
Automatic cold junction compensation; temperature readings in degrees Fahrenheit (Celsius optional).
System options and accessories include key lock security to prevent accidental or unauthorized program changes, proportional output, remote thermocouple amplifiers (sending units), remote display repeaters, data logging and graphing with a PC.
