Product Details

Product Features

The button automatically deducts the environmental radiation background, no need for zero adjustment.

Current and Curie (Ci), Becquerel (Bq) can be used as two display unit options.

Keyboard modification and solidification of nuclide calibration coefficients, no need for development tools

Specialized thermal printer output for nuclide activity measurement report. (Optional)

Measurable nuclear medicine internal therapy radionuclides such as 153Sm, 90Y, 186Re, and the positron-emitting radionuclide 18F, etc.

Place the sample, automatically perform the measurement and range conversion; the measurement is fast and accurate, and the measurement range can reach 10 curies (99mTc).

Up to 100 radionuclides can be set, and dozens of radionuclides and commonly used radionuclides in nuclear medicine (such as 99mTC, 113mIn, 131I, 125I, 67Ga, 201Ti, etc.) can be directly measured.

Place the sample, automatically perform the measurement and range conversion; the measurement is fast and accurate, and the measurement range can reach 10 curies (99mTc).

The computer can fully take over the functional operation of the activity meter on the Chinese Windows platform and can independently set the serial port address, scan rate, data storage rate, and panel nuclide.

The total measurement accuracy may be affected by the following factors: electrometer accuracy, the accuracy of the standard coefficient for the specified nuclide, sample composition, and some correction factors for vials or syringes, as well as the accuracy of the standard source used for electrometer calibration.

Display full scale (FSD) (2000). System accuracy is better than ±2 minimum display digits in Bq mode.

Linearity includes the response of the ionization chamber to high-activity samples and the range variation of the electrometer.
