The intrinsically safe versions of the new miniature resistance thermometers — TR21, TR31 (OEM) and TR34 (photo) — now also have the CSA (Canadian Standards Association) test mark for ignition protection type Ex i. The seal of the CSA Group facilitates the use of thermometers in North America. In addition, all three instrument types have ATEX and IECEx approval. The new miniature thermometers are designed for use in industrial applications. Their design is extremely durable, and an autoclavable version is available for sanitary applications. All models are designed for a temperature range of –50 to 250°C. — Wika Alexander Wiegand SE & Co. KG, Klingenberg, Germany
