    Temperature Range

    -20°C to 150°C

    Temperature Uncertainty

    Standard radiometric calibration: ±1°C at 8 to 14 µm
    Optional thermometric calibration: ±0.1°C (only on 14750-4C and 14750-5C)
    Accuracy is defined for an ambient temperature of 18 to 23°C

    Temperature Resolution



    ±0.1°C per 8-hour period
    Provided stable AC mains voltage and minimum air flow across the exit port or emitter plate

    Source Non-Uniformity

    ±0.2°C less than 100°C, ±1.3°C greater than 100°C
    Emitter uniformity is defined for 1.6” (40 mm) diameter of the central area

    Heated Emitter Shape

    Flat plate

    Exit Port Diameter

    51 mm (2 in)


    Radiometric calibration: 1.0 at 8 to 14 µm
    Thermometric calibration: ~ 0.98

    Calibration Method

    Standard: Radiometric (pyrometric)
    Optional:  Thermometric (only on 14750-4C and 14750-5C)

    Temperature Sensor

    Precision platinum RTD

    Warm-Up Time

    ~ 6 minutes from ambient to -15°C or 100°C
    Typical — can vary from unit to unit

    Slew Rate to 1°C Stability

    ~ 40° per minute from ambient to 150°C
    ~ 20° per minute 20 to 10°C
    ~ 3° per minute from -10 to -20°C
    Typical — can vary from unit to unit

    Slew Rate to 0.1°C Stability

    Approximately 2 minutes between Δ 10°C setpoints (slightly longer T < -10°C)

  • Communication / Interface

    Remote Set Point

    Via RS232

    Method of Control

    Digital self tuning PID controller

  • Environmental Specifications

    Operating Ambient Temperature

    5 to 40°C
    To achieve low temperature set point of -20°C, ambient must be ≤25°C (77°F).
