APPLICATION: EQUIPMENT CALIBRATION
RCD - The standard by which others are measured!
RCD has been manufacturing precision resistors for more than 30 years, which have evolved into some of the most precise and stable standards available worldwide, up to 10 times more accurate than competitive models!
Series A1: Made of premium resistance wire, wound on insulated brass spools for precise matching of TCE, and pre-conditioned to assure utmost stability. The element is immersed in moisture-free oil inside a sealed metal container. A vailable in two grades, A1A to ±0.0005% and A1B to ±0.001%. A1A standards are not only traceable to the NIST, but also include a computerized TC chart giving corrections for every 0.01°C from 18 to 30°C. Series A1 are p rovided with a thermometer well at the center of the standard. As an option, a 100 Ω platinum RTD element (RCD type PTF1 accurate to 0.1°C) can be imbedded in the midst of the resistance windings. Heavy duty leads enable series/parallel connections without compromising the guaranteed limit of error.
Series A2: Precision resistors with 4-terminal brass binding posts designed for less critical applications such as secondary reference standards. Molded low- profile case with flexible internal insulation protects the resistance element from damage even when exposed to non-laboratory environments, such as production or R&D departments. Gold plated binding posts available.
Designed for use as DC Resistance Standards in industrial, research, and metrology laboratories
Standards are individually tested and certified to the National Institute of Standards and Technology
Accuracies to ±0.0005%!
Choice of models: A1 offers utmost precision and stability for ‘primary standard’ applications, A2 offers economical ‘secondary standard’ performance
Values from 0.01 Ω to 1M Ω are standard (any decade or intermediate value can be offered on a custom basis from 0.001 Ω to 10 13 Ω , consult factory)
Low thermal EMF and voltage coefficients
RCD standards lab offers recalibration services
Low temperature coefficient (approx. 10ppm/°C)
Operating temperature: 0°C to +40°C
Low cost 2-terminal banana plug standards avail.
