Frequently Asked Questions
What makes the Arjun 30 different from other Modsonic flaw detectors?
The Arjun 30 is Modsonic’s lightest conventional flaw detector at just 800g with battery. It combines one-hand operation, a high-resolution 5-inch WVGA colour display, a Square Wave Pulser, on-board DGS/AVG, dynamic DAC, AWS D1.1 software, and up to 100 hours of built-in A-Scan and B-Scan recording — making it ideal for documentation-heavy field inspection.
What is the test range and frequency range of the Arjun 30?
The Arjun 30 covers a test range of 2.5 mm to 10 metres in steel with Fine mode adjustable in 1 mm steps, and a wideband frequency range of 0.5 MHz to 15 MHz.
How much data can the Arjun 30 store and record?
The Arjun 30 can store 500 A-Scan trace patterns and 50 calibration set-ups. It also supports continuous A-Scan and B-Scan recording for up to 100 hours on an 8 GB Micro SD card. Data can be transferred to a PC via USB port or stored directly on a Micro SD card (up to 32 GB) or external USB disk.
What is the B-Scan feature on the Arjun 30?
The Arjun 30 displays a real-time colour coded un-encoded B-Scan alongside the A-Scan on screen simultaneously. The B-Scan can be recorded, transferred to a PC, and analysed both in the machine and in ArjnSoft30 PC software — making it valuable for evidence, documentation, and reporting.
What are the DGS and DAC capabilities of the Arjun 30?
The Arjun 30 features on-board DGS/AVG for defect size evaluation using predefined and custom probe set-ups, with ERS (Equivalent Reflector Size) displayed directly on screen. Its auto-plotting dynamic DAC generates a smooth parabolic curve with selectable offset curves from 0 to 14 dB in 0.1 dB steps, using 2 to 10 reference points.
What is the battery life and weight of the Arjun 30?
The Arjun 30 weighs only 800g including the Lithium-Ion battery (7.4V DC, 5 AH) and delivers 8 hours of continuous operation on a full charge. An external charger is provided so the battery can be charged without occupying the main unit.
What compliance standards does the Arjun 30 meet?
The Arjun 30 is compliant with EN 12668 and ASTM E317 ultrasound standards, and includes built-in software for weld defect evaluation in accordance with AWS Specification D1.1.
