Pen Point
Markers

NIST Traceable
Calibration &
Versatile, Durable.

Features

ERS rod sources and Pen Point Markers are calibrated by direct comparison of standardized solutions traceable to the National lnstitute of Standards and Technology (NIST), in an identical geometry, using a pressurized ion chamber with ±5% accuracy.

ERS rod sources can be supplied in set or invidually in accordance with customer request

Rod Source dimensions are
12.7mm x 127mm (0.5” x 5”)
12.7mm x 74.9mm (0.5” x 2.95”).

ERS offers a wide range of rod sources that are used for calibrating well counters and thyroid uptake systems. Rod sources are constructed of acrylic material and have a flat base which allows easy positioning in the vertical position required for consistent accuracy of the calibration process.
