  2670 Farmer Dosemeter


The 2670 Farmer Dosemeter offers excellent stability and easy operation via large, clear menus. The instrument offers precise measurements of radiological beams with a choice of operational software. 
   Product Detail


The 2670 features traditional qualities with excellent performance achieved by state-of-the-art technology. In use, all menus, options and values are selected by two rotary knobs, giving a real "hands-on" feel to the instrument. A Chamber library and a Type library are included within the Calibration Mode, whose settings are protected by a keyswitch. The NE2670 measures dose, doserate, charge or current and includes a data link for 2-way communications with an external computer.

The 2670 is available in 2 variants:

  • The 2670A features a serial control option, for control and data collection by an external computer.
  • The 2670B features enhanced background calculation and supervisor options.

Please contact our sales stafffor more information.
