Detailed Overview

The GD-2 is a portable, transmission-type digital densitometer designed for industrial radiography. It provides precise measurements of the optical density (blackness) of processed X-ray film to ensure compliance with international standards such as ASME or ISO.

Features & Benefits

• Measurement Range: 0.00D to 4.20D (Optical Density).

• Precision & Accuracy: Accurate to within ± 0.03D.

• User Interface: Easy-to-read, backlit 3-digit LCD display.

• Efficiency: Features a dedicated “Zero” button for quick calibration and an automatic power-off function to conserve battery life.

• Spot Measurement: Equipped with a 4mm aperture for precise density readings on specific areas of the film.

Primary Uses & Functions

• Quality Control: Functions as a critical QC tool in the Radiographic Testing (RT) process.

• Compliance Verification: Measures film density to meet minimum and maximum code requirements.

• System Compatibility: Designed for use alongside X-ray film processing systems and film viewers/illuminators in industrial darkrooms.

Technical Specifications

Compatibility

• Used in conjunction with X-ray film processing systems and darkroom equipment.
