NM01W138

The Model W138 Direct-Reading Dosimeter is a reliable and straightforward instrument for monitoring personal exposure to gamma and X-ray radiation. With a measurement range of 0 to 200 milliroentgens (mR), this dosimeter provides immediate, on-the-spot readings of accumulated radiation dose.  

This self-reading dosimeter operates without the need for batteries or external power. It utilizes an ionization chamber that discharges proportionally to the amount of radiation encountered. The accumulated dose is directly viewed by holding the dosimeter up to a light source and observing the position of a hairline indicator on an internal scale through the built-in window.

The Model W138 is designed for simplicity and ease of use, making it an ideal choice for individuals who need immediate awareness of their radiation exposure. Its rugged construction ensures durability in various working environments.
