Universal radiation protection 

The new 62AD succeeds the trusted 6150AD dose rate meter, continuing the Automess legacy for of precision, reliability, and durability. This newest generation has two versions to meet different application requirements:

  • 62AD25 with standard range: 1 μSv/h to 25 mSv/h
  • 62AD50 with extended range: 1 μSv/h to 50 mSv/h

Only the 50 mSv/h variant holds a PTB type examination certificate (No. DE-25-M-PTB-0032), making it approved for official calibration and conformity assessments.

With a familiar two-button layout, intuitive menu navigation, and a new light sensor for automatic LED backlight control, the 62AD offers improved usability in any lighting condition. The device's housing is now milled from solid aluminium making it light but durable, and the housing's colour can be customised by users when ordering.

Features

  • Two measuring ranges:
    • 1 μSv/h to 25 mSv/h
    • 1 μSv/h to 50 mSv/h (PTB-certified version)
  • Automatic range switching with sliding time constant for accurate, responsive measurements
  • High-precision digital calibration ensures consistent and reliable dose rate readings
  • Simultaneous readout of:
    • Instantaneous dose rate
    • Average dose rate
    • Maximum dose rate
    • Cumulative dose (non-volatile memory)
  • Approx. 3,000 hours of operation with a standard 9V alkaline battery
  • Solid aluminum housing – waterproof, robust, and available in customizable colors
  • Automatic LED backlight controlled via integrated light sensor for optimal visibility
  • RS232 serial interface for PC connectivity and data transfer

Response time
Coefficient of variation
  • Fast 62AD (conforms to IEC 60846-1):
    • 5 μSv/h to 25/50 mSv/h
    • (PTB) (62AD25/62AD50)
    • Time constant 4 s
    • Coefficient of variation < 5 % at ≥ 55 μSv/h
  • Slow 62AD:
    • 1 μSv/h to 25/50 mSv/h
    • (PTB) (62AD25/62AD50)
    • Time constant floating 20 s to 4 s
    • Coefficient of variation < 5 % at ≥ 11 μSv/h
Apparative zero effect  < 50 nSv/h
Linearity of the dose and dose rate measurement –12 %…+14 % (PTB) (permissible: –13 %…+18 %) related to 1 mSv resp. 10 mSv/h
Overload Exceeding the end value of the measuring range by up to 50 times, i.e. by up to 1250/2500 mSv/h (62AD25/62AD50) is detected. Device is still functional after overload (PTB)
Dose measuring range 0.1 μSv to 999 mSv (PTB)
Detection of individual pulses 0.1 μSv/50 nSv/h = 2 h if you want to utilize the lower limit of the dose-measuring range of 0.1 μSv with an instrument zero effect of 50 nSv/h
Freely programmable alarm thresholds One alarm threshold each for dose rate and dose
Fixed alarm thresholds There are several alarm categories (sets of fixed alarm thresholds) to choose from
Climate (nominal operating ranges of ambient temperature and relative humidity) −20 °C to +60 °C and 0 % to 95 % relative humidity, deviation -1 %...+2 % (PTB) (permissible: –13 %…+18 %) related to display at +20 °C and 65 % relative humidity (below -10 °C the LCD reaction will get slower)
Atmospheric pressure Nominal operating range 60 kPa to 130 kPa (600 mbar to 1300 mbar)
