Type 341, 342, and 347 dial thermometers are field thermometers with narrow annular enclosures. The casing, immersion pipe and fittings are made of stainless steel. All equipment complies with EN 13190 and meets Class 1 requirements. These devices are available in a variety of nominal sizes from 63 to 160 mm. Due to the narrow case, the thermometer is permanently sealed (IP65), perfect for filling the case with silicone oil (optional). We recommend this version with casing fill for applications affected by vibration. We offer many different display ranges, measuring ranges from 80 to 600K. In connection, our standard range includes eight different designs, six different connection types, a variety of connection threads and a variety of immersion tube lengths and diameters. Together, these versions provide an optimal solution for almost any application.
