    Calibration from -100 to 155ºC
    Calibration from -100 to 50ºC by Stirling cooler and calibration from -30 to 155ºC by Peltier device is available.
    Reduce the heating/cooling time
    KT-H503 (-100 to 50ºC type) : 23ºC to -100ºC at about 40min.
    KT-H504 (-30 to 155ºC type) : -30ºC to 155ºC at about 20min.
    Excellent temperature stability and temperature distribution
    KT-H503 (-100 to 50ºC type) : ±0.03ºC per 30min.
    KT-H504 (-30 to 155ºC type) : ±0.01ºC per 30min.
    Within 0.1ºC (40mm from the bottom), within 0.01ºC (between wells).
    Simple temperature setting
    Select 8 preset temperature points by simple selecting button.
    Calibration test report (option)
    CHINO calibration test report available.
