Professional FAQ for the 3300 NSv Probe

• What target surface material works best for this probe? The probe requires a conductive material like steel. Use AISI 4140 or similar for optimal performance.
• Can I shorten or extend the 1.0-meter probe cable? No. Modifying the cable length will change its electrical characteristics and invalidate calibration.
• How does the Viton O-ring handle different fluids? Viton provides good resistance to oils and hydrocarbons. Avoid prolonged exposure to ketones or strong acids.
• What is the expected service life of this probe? Service life depends on the environment. With proper installation, expect many years of reliable operation.
• Is special cleaning required for the probe tip? Keep the tip clean and free of debris. Use a soft cloth and isopropyl alcohol if necessary. Avoid scratching the PPS surface.
