Tips of Selection
- The medium to be measured shall be compatible with the material contacting with the product.
- The code E, an additional functional code for selection, and intrinsically safe explosion-proof Ex ia II CT5 must be power supplied via safety barrier.
- Please contact us in case of the other special requirements and clearly indicate them when placing an order.
