DMC 3000

In addition to the passive dosimeter, which is sent out every month or quarter, the DMC3000s active dosimeter gives you the radiation dose received instantaneously at T0 and T1.   Calibration once a year is imperative     It can either be used on its own (stand-alone mode), or placed on a base (satellite mode) with data retrieval for better operator monitoring. 2 types of pre-alarm and alarm :

• Received dose alarm
• Dose rate alarm

• Audible alarm, 85 dB (A), (> 90 dB (C) peak)
• Vibrating alarm
• Backlit display for improved visibility
• Additional beta, neutron and telemetry modules
• Factory software update
• Simple 2-button navigation
• Extensive dose rate alarms
• Visual alarm with 2 ultra-bright LEDs
• Excellent gamma and X-ray energy response

• from 0.1 μSv/h to 20 Sv/h
• Saturation indication above 10 Sv or 10 Sv/h
• Dose rate linearity :
• < ± 20% up to 10 Sv/h (Co and X H30 20 keV)

• Standard AAA alkaline battery (LR03) 1.5 V
• 9 calendar months of standard use (8 hours a day, 5 days a week in "measurement" mode, without excessive alarm)*.
• 2500 hours of continuous operation, without excessive alarm* (*0.2% of time in alarm)

• Robust, impact-resistant ABS-polycarbonate case
• Dimensions: 87 x 60 x 21 mm max. without clip
• Weight with alkaline battery and clip: < 88 g
• Carried with a replaceable clip (2 types of rear clip and one front clip, for securing the DMC inside a pocket)

• • Operating temperature: -10°C to +50°C (response variation less than ± 5%)
  • Relative humidity: < 90% at 42°C
  • Storage: -20°C to +71°C
  • Shock-, vibration- and drop-resistant (1.5 m on concrete)
  • Waterproof to IP67: 1 meter for 1 hour
  • EMC: far exceeds minimum requirements (compliance) -- MIL STD 461F RS103 (Pulsed electromagnetic fields) greater than 200 V/m from 10 kHz to 5 GHz -- MIL STD 461F RS101 (Magnetic fields 30 Hz to 100 kHz)
  • Factory calibration to ISO/CEI 17025, COFRAC accreditation N°2-1663

• • Dose increments with a resolution of 1 μSv are stored in non-volatile memory (EEPROM) at configurable intervals (10 s, 60 s, 10 min., 1 hour, 24 hours).
  • Dose rate is saved at each dose increment using the new communication protocol
  • Events (alarms, faults, modifications) are saved within the selected time period.
  • Input and output data from several consecutive workers (over 1000 measurements) are recorded

• Large LCD display with high-quality white backlighting
• 8-character alpha-numeric display for full name display (scrolling) and fixed display format for dose and flow rate
• 3 LEDs on top for alarms (red), gamma count (green) and Hp (0.07) or neutron count (blue)

• Audible alarm with level of 85 dB (A) typical (> 90 dB (C) peak) at 30 cm, frequency < 4800 Hz
• Vibrating alarm
• Ultra-bright red flash LED on front panel
• 3 LED displays on top and indicators on display
• Dose/rate alarms, adjustable over display range
• Dose/rate pre-alarms, adjustable and recognizable in display range, acknowledgeable
• Remaining time alarm (before dose alarm) and duration alarm
• Hands-free communication, frequency: 125 kHz
• Upward compatibility with existing readers (LDM 2000 and LDM 220/210)
• Communication with LDM 220: 10 cm
• Improved communication protocol offering new features for the DMC 3000 in conjunction with readers (LDM 320D, LDM 320W and LDM 2000, LDM 3200 (*)) * Requires software update
