This small form SPRT is designed for situations when using a traditional SPRT is unsuitable due to their length. The small 5686-B glass is 5.8mm in diameter and 56mm long, so is suited for applications such as cryogenics, calorimetry, and other metrology work requiring small SPRTs.
Complies completely with ITS-90. Resistance ratios of W(302.9146 K) ≥ 1.11807 and W(234.3156 K) ≤ 0.844235. Covers temperatures from –260°C to 232°C.
