| Series A1: Made of premium resistance wire, wound on insulated brass spools for precise matching of TCE, and pre-conditioned to assure utmost stability. Available 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 provided with a thermometer well at the center of the standard. As an option, a 100Ω 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. |
