Should I purchase brass or stainless steel Vapor Pin® sampling devices?
The typical use of the Brass Vapor Pin® sampling devices are for temporary installations (one-time sampling) and stainless steel for long-term installations (repeated sampling), due to the superior corrosion resistance of stainless steel. If there is any doubt, we recommend purchasing stainless-steel pins, as the additional cost is a small part of overall costs, particularly after the Vapor Pin® sampling device has been used multiple times.
