Fiber Optic Thermometer [FIMTHERM HM-2]
A new type of thermometer that achieves instant and accurate measurements! - The only thermometer that can measure the temperature within molten metal with a fast response time (approximately 0.02 seconds).
Our optical fiber thermometer is a completely new type of thermometer that uses a metal tube-coated optical fiber (FIMT) in the light guide section of a radiation thermometer, immersing its tip directly into molten metal for temperature measurement. By immersing it, we achieve instant and accurate temperature measurement. 【Features】 - Compact and lightweight for easy portability - Reduced temperature measurement costs - Simple operation for measurement - Wide measurement range (from low temperatures of 250°C to high temperatures of 3000°C) - High precision measurement unaffected by disturbances or reflectivity - Fast response (approximately 0.02 seconds) - Resistant to electromagnetic noise 【Specifications】 - Temperature range: 800-1800°C (standard, InGaAs element), with other ranges available such as 250-800°C, 1000-3000°C, etc. - Response speed: 20 msec (standard) - Dimensions: 180×440×440 mm - Weight: 9.6 kg
