Remspec has always offered corrosion-resistant probe heads in a variety of special alloys such as 316 SS, Hastelloy, nickel, titanium, and many others. Now we can offer, at moderate cost, probe heads that have all wetted metallic parts coated with a pinhole-free, chemically-bonded 50 micron thick layer of tantalum. This is ideal for strong acids and many oxidizing environments. Tantalum is FDA approved and a tantalum probe is the ideal match for a glass lined reactor. Tantalum-coated probes tend to be less expensive than the same item in Hastelloy.
