Miniature Wire
Miniature Wire
Miniature wire probes have 5 µm diameter, 1.25 mm long platinum-plated tungsten wire sensors. The wires are welded directly to the prongs and the entire wire length acts as a sensor.

Gold-plated Wire Probes
Gold-plated Wire Probes
Gold-plated wire probes have 5 µm diameter, 3 mm long platinum-plated tungsten wire sensors. The wire ends are copper- and gold-plated to a thickness of 15 to 20 µm, leaving an active sensor, 1.25 mm, on the middle of the wire.

Fiber-film
Fiber-film
Fiber-film probes have cylindrical thin film sensors and may be used as a substitute for wire probes in liquids or in gas applications where more robust probes are needed. They are considerably more rugged than wire probes and less sensitive to contamination. Fiber sensors are 70 µm diameter quartz fibers, 3 mm long, covered by a nickel thin film approx. 0.1 µm in thickness.

Split-fiber
Split-fiber
Split-fiber probes have two parallel nickel films deposited on the same quartz fiber, 200 µm diameter and 3 mm long. The ends are copper- and gold-plated, leaving a 1.25 mm sensing length. The film is protected with a 0.5 µm quartz coating.

6mm Probe Supports
6mm Probe Supports
There are three probe support types available for dual-sensor probes: short, long straight and long right-angled. The supports consist of a coupling ring with an internal rubber ring that provides a water- and pressure-tight sealing, and two sets of contacts embedded in a cylindrical body that ends in one or two PTFE-coated cables with detachable BNC connectors.
