Temperature and Humidity

NSAI NML can calibrate the following instruments:

• Digital Temperature and/or Humidity indicators and recorders, with temperature sensors
• Resistance thermometers, calibrated by comparison
• Resistance thermometers, fixed point calibration
• Fixed point cells
• Thermocouples up to 660 °C
• Dry Block ‘calibrators’
• Temperature calibration baths
• Humidity generators
• Temperature and/or Humidity Data-loggers
• Chart recorders
• Dial temperature gauges
• Liquid-in-glass thermometers, mercury filled
• Liquid-in-glass thermometers, spirit filled
• Thermostats
• IR thermometers
• IR calibrators

The NSAI NML maintains temperature fixed point standards, covering a temperature range
from -38 °C to +420 °C,ensuring that calibrations performed by the NSAI NML have direct
traceability to the International Temperature Scale of 1990 (ITS-90).
