Product Overview
Dekastat SP1298 Decade Resistor Rack – Used, Vintage Pre-1970 Laboratory Standard
Used, vintage laboratory instrument with visible institutional history. Basic electrical testing confirmed functional switching, continuity, and consistent resistance behavior across all ranges. Original inventory tags remain affixed. Unit only, no cables or accessories included. Typically ships same business day from Idaho warehouse. Delivery to lower 48 states usually 3-5 business days.
The Dekastat SP1298 decade resistor rack provides selectable resistance values through rotary decade switches, allowing controlled substitution during electrical testing and calibration work.
Product Condition
Used, vintage pre-1970. Shows minor marks and scuffs consistent with careful laboratory use. Rotary switches turn smoothly and were tested operational. Original institutional tags remain in place, indicating long-term controlled use.
Product Overview
Dekastat was known for manufacturing laboratory-grade resistance standards used in calibration, circuit development, and technical education. The SP1298 reflects mid-century test equipment design, emphasizing mechanical durability, stable resistor networks, and clear manual control. Its rackmount format and broad resistance range made it suitable for permanent bench or system integration in laboratory environments.

Frequently Asked Questions
What resistance range does the SP1298 cover?
The unit provides selectable resistance from 0.01 ohms up to approximately 11 kilohms through its decade switches.
What testing was performed?
Basic electrical testing confirmed proper switching, continuity, and consistent resistance behavior across all selectable ranges.
What do the inventory tags indicate?
The visible tags include a 1970 inventory label with an earlier label beneath it, suggesting extended institutional service prior to that date.
Is this suitable for certified calibration work?
While functional, it is best suited for educational, experimental, restoration, or demonstration use rather than certified metrology calibration.
Who used equipment like this originally?
Decade resistor racks like the SP1298 were commonly used in research laboratories, educational institutions, and industrial test environments.
Built for laboratories where stability mattered more than screens, the SP1298 stands as a working example of analog precision, ready to support its next set of experiments or demonstrations.
