Description

PNM-200 is the lightest portable neutron survey meter based on polyethylene sphere in the market. It measures both the neutron dose equivalent since the instrument was last powered on and the neutron dose rate equivalent.

PNM-200 comes in a compact housing that features an ergonomic handle. It is self contained, needing no external device or connection to operate.

PNM-200 is largely used in Nuclear Power Plants, fuel processing and spent fuel reprocessing plants, and accelerator facilities. It represents the right solution for transportation shield leakage measurements and for all measurements that must be performed in contact.

PNM-200 is the instrument of choice when gamma background may impact the final neutron measurement taking its good gamma rejection into account (>1000:1).

The backlight (selectable via the power switch) makes the LCD display easy to read even in dark areas.

A rotary switch gives access to the following data:

• Internal test procedure
• Integration time (since powered on)
• Integrated dose equivalent
• Dose-rate equivalent
