Standard radiation thermometer IR-RST

Product catalog summary

Introduction
The IR-RST series of Standard Radiation Thermometers has been developed in collaboration with the National Metrology Institute of Japan (NMIJ) to ensure traceability in calibrating conventional radiation thermometers. These thermometers adhere to the Japan Industrial Standard JIS C 1612.

Models and Calibration
Two models are available: the 0.9µm model and the 0.65µm model. The 0.9µm model offers JCSS calibration for temperatures ranging from 400 to 2000ºC using fixed point and comparison calibration methods. The 0.65µm model extends calibration up to 3000ºC, utilizing high-temperature fixed point blackbody furnaces.

Features
The IR-RST series features high precision and small uncertainty in temperature measurement, with internal temperature control to eliminate output variation due to ambient temperature changes. The 0.9µm model supports 4-fixed points calibration, while the 0.65µm model uses metal-carbon eutectics fixed points.

Applications
These thermometers are suitable for use in National Standard Laboratories and Calibration Agencies, as well as for quality control in high-temperature furnace manufacturing and usage.

Specifications
The IR-RST90H and IR-RST65H models use a monochromatic radiation thermometer method with a silicon photo diode detecting element. They offer a measuring range of 400 to 2000ºC and 1000 to 3000ºC, respectively, with a resolution of 0.1ºC. The response time is 2 seconds or less, and they feature a focusable lens optical system.

Calibration Test
Calibration is classified under JCSS and CHINO, with various methods and ranges specified for each model. The uncertainty varies depending on the temperature range, with detailed calibration points and documentation provided.

STANDARD RADIATION THERMOMETER Model IR-RST series Standard Radiation Thermometer IR-RST series has been developed under collaborative research with the National Metrology Institute of Japan (NMIJ). The IR-RST series as Standard Radiation Thermometers are applicable for traceability of calibrating conventional radiation thermometers. Based on Japan Industrial Standard JIS C 1612 (Test methods for radiation thermometers), two models of 0.9µm and 0.65µm in measuring wavelength are prepared. 0.9µm model supplies JCSS** calibration which certifies temperature range from 400 to 2000ºC by fixed point calibration method with fixed point blackbody furnace IR-R0 (Zn 420ºC to Cu 1085ºC) and comparison calibration method with comparison blackbody furnace IR-R8. 0.65µm model supplies calibration upto 3000ºC by fixed point calibration method and comparison calibration method with high-temperature fixed point blackbody furnace IR-R80 utilizing metal-carbon eutectics fixed points (upto 2474ºC) developed by NMIJ. JCSS** = Japan Calibration Service System FEATURES Undertaking collaborative research with NMIJ, specifications and performance as high-precise standard radiation thermometer is realized. By utilizing two models of 0.9µm and 0.65µm units, calibration from 400 to 3000ºC with the small uncertainty is realized. 0.9µm unit is applicable for 4-fixed points calibration by JCSS. 0.65µm unit can be calibrated on high-temperature fixed point furnace utilizing metal-carbon eutectics fixed points. (Φ0.6mm at 400mm) Embedded internal temperature control eliminates the need for output variation compensation against ambient temperature. Prepare various calibration test in accordance with uncertainty. APPLICATIONS Standard Radiation Thermometer for National Standard Laboratories, or Calibration Agencies High-precise Radiation Thermometer for the purpose of delivery inspection, periodical check and quality control at blackbody furnace user, high-temperature furnace manufacturer and user.
