Pressure Transmitter - R-1
Brand: WIKA Alexander Wiegand SE & Co. KG
The model R-1 pressure transmitter has been optimally designed for the specific requirements of refrigeration and air-conditioning applications. Its monolithic construction dispenses with the need to use seals on the process side. This enables the model R-1 to be used with all typical refrigerants (e.g. freon and ammonia).
Features- Wetted parts from stainless steel.
- Resistant to all common refrigerants.
- Special case design for the best possible condensation tightness.
- Private labelling possible.
