The 2130 Mini-ION is setting new standards in versatility, accuracy, operational simplicity and reliability, for the measurement of Gamma,Beta and X-ray radiation. The instrument offers analog doserate display in five ranges, from 1.0 µSv/h to 500 mSv/h. Calibration and setup can be performed by PC via serial link, offering greater security and accuracy than traditional screw-adjustment meters.
Product Detail
The Model 2130 Mini-ION is a portable, battery operated ion chamber survey meter.
It is intended for use in cost-sensitive applications where sophisticated features such as digital readout, data logging and autoranging are not necessary. The meter covers a wide gamma energy range from 10 keV to over 6 MeV and includes a movable window shield to facilitate gamma only measurement in mixed beta/gamma fields. The effective dose rate range is from 1.0 μSv h-1 to 500 mSv h-1 in five ranges. The dose rate or dose value is displayed on a clearly scaled analogue meter. Special circuitry ensures that the effect of physical meter movement on the readings is minimized without compromising the response time.
Meter functions are accessed via sealed, wipe-clean membrane switches. Operation is simple with the appropriate dose or dose rate range being selected by range up/down buttons. The buttons are situated on the carrying handle for convenient single-handed use. The selected range is indicated by a bright, high efficiency LED.
The key characteristic of the 2130 is ability to be calibrated using a remote link to a PC. The link is established by attaching an RS232 interface between the meter and PC and running software provided. This has a number of advantages. It makes the calibration process more efficient by reducing calibration time (no controls to adjust), improves accuracy and ensures secure storage of calibration data in non-volatile memory.
The 2130 will meet the majority of survey meter applications where mixed gamma and beta fields are encountered, for example, as found in nuclear power or fuel processing plants.
