Shipping & FAQ

• Shipping Carriers: FedEx, UPS, DHL (Express worldwide).
• Q: Can I use this probe below -34°C for many days? A: No. Long exposure below -34°C may break the pressure seal.
• Q: What is the linear range starting point? A: Linear range begins at 0.25 mm (10 mils) from the target surface.
• Q: Do I need an approval option for safe areas? A: Use -00 option (Not required) for non-hazardous locations.
• Q: How long can my field wiring be? A: Maximum 305 meters (1,000 feet) between Proximitor Sensor and monitor.
