DSHD-3022 Microcomputer Four Channel γ Spectrometer
Function:
1.Having 4 channels to be counted at the same time, and
displaying counting rate of 4 channels by turns as
well as displaying content of U, Th, K and total amount.
2. Ding Ur and Th to Cs to affect revision and enhance signal quality of
reference source. Using micro PC to seek peak and track spectrum shift
automatically,And stable the spectrum.
3. Equipment can deduct background value automatically.
4. Counting rate output of 3 channels like U, Th and K is all normalized to the
value of 100s, and total counting rate will be all normalized to the value of
10s.
5. Self-stable status will be indicated on table head.
6. Having radioactive abnormal noise
alarm, which can choose among 15×10-6-200-6 in abnormal alarm switch according
to uranium content in all.
7. Seting alarm if batteries invalid and probe without signal.
8. High sensitivity, portable, light weight, firm and reliable, fit for field
work.

Main
Parameters
1. Content sensitivity threshold: uranium:
1*10-6 thorium: 2*10-6 Potassium: 0.2%
2.Content measuring range: uranium: 1*10-6~1000*10-6 thorium: 2*10-6~1000*10-6 Potassium: 0.2%~100% Total channel:
2*10-6~1000*10-6
3. Usage environment:
The instrument can be worked normally in the temperature of -100C~+550C or
temperature +400C and relative humidity 95%. Comparing to each channel counting
rate in normal climate condition and limit condition, the relative error is no
more than±15%.
4. Repetition: under the same measurement condition, if you do continuous 20
times measurement to the same component, the relative standard deviation is no
more than ±10%.
5. Stability: stable for 8 hours, the relative error is no more than ±10%.
6. Power and consumption: six 1# batteries, currency is ≤90mA
7. Equipment dimension and weight:
Operation desk: volume: 220*105*175mm,
weight: 2.6kg (batteries not included)
Probe: length: 490mm, max. diameter:
100mm, weight is about 3.0kg
