Fiber optic thermometers are immune to electrical, magnetic (EMI), radio frequency (RF) and microwave interference. Unlike other metal thermocouples and thermistors, fiber optic probes can be directly used in high voltage, electricity, magnetism and microwave applications without any damage to electronic equipment or fiber optic instruments. The probe is PFA Teflon coated so it can be used in corrosive chemical environments, 100% non-metallic, does not generate any sparks for flammable and explosive environments.

Fiber optic probes can withstand higher temperatures. For example, the IMPAC fiber optic thermometer probe can withstand high temperatures of 250°C without water cooling, and is not interfered by electromagnetic radiation, and the output signal is stable. It is a model with excellent performance among infrared thermometers. IMPAC China Service Center can provide technical services such as maintenance and replacement of fiber optic probes.
