Chi tiết:
Kính thưa quý khách hàng,
Hiện nay chúng tôi đang có sẵn hàng máy AT1121, máy này có thể đo phóng xạ, tia X, đo tốt cho máy gia tốc (máy soi xe container, máy gia tốc trong y học hạt nhân, các loại máy gia tốc phát tia X,...) vì chúng phát năng lượng cao cỡ vài MeV, đặc biệt đo tốt cho phòng X-Quang vì tốc độ nháy tia X của máy X-quang là rất cao, thời gian phát tia ngắn, những thiết bị đo chậm khác không đáp ứng kịp.

INTRODUCTION
The Model 9DP-1* is a variant of the highly sensitive Model 9DP-1
pressurized ion chamber meter that provides measurements of
ambient dose. Ambient dose equivalent is defined as the dose
equivalent readout that would be measured at a (human) tissue
depth of 10 mm. This requires a special ion chamber that can provide
a conversion of the (air kerma) exposure rate to provide the ambient
dose and dose rate.
Just like the Model 9DP-1, the Model 9DP-1* can correctly integrate
50 nanosecond pulses that other systems typically miss or measure
inaccurately. The instrument can also simultaneously display the
exposure rate, integrated value, and highest rate seen by the
instrument. The detector chamber is only pressurized to 2.5
atmospheres (22 psig), thus avoiding USA HAZMAT concerns
for shipping and handling. However, this reduced pressure also
reduces sensitivity, so the minimum "good" measurement point is
only 2 μSv/h (200 μR/hr).
The 256K color, bit-mapped display provides an optimized
presentation of the data and is accompanied with icons informing
the user of the active functions and instrument status. Alarms
are indicated using color changes on the display and an audio
output. The instrument is powered using NiMH type rechargeable
batteries that deliver up to 30 hours operation between charges.
Measurements can be logged to a USB drive plugged into the
instrument USB port. Data are written in CSV format for convenient
retrieval by a PC spreadsheet or database program.
Ludlum also offers a Dimension Interface Package that facilitates
complete setup and calibration programming under administrator-
controlled password protection.
