The SR Series provides the same dimensional accuracy as the R series but is manufactured from AISI 440C stainless steel. This makes them the definitive choice for precision tasks in environments where moisture or chemical exposure is a factor. They are extensively used in food-handling equipment, outdoor sensors, and medical instruments.
