Model 1262A Miniature Probe
Designed for one component, cross-flow applications. Right angle bend in the support needles and small diameter of the probe body minimize flow disturbances and make it ideal for difficult-to-reach locations. Available in hot wire and hot film versions for gases (up to 150°C) and hot film version for liquids.
