As QSA Global’s newest gamma-ray source projector, the 1100 delivers enhanced safety, easier operation, and double the service life, building on the proven performance of the [880 Series](https://www.qsa-global.com/880-series-gamma-ray-source-projectors?hsLang=en). A new ergonomic handle makes the projector more comfortable to carry, and a larger label area supports required IATA transport markings, eliminating the need for overpack labels. Backward compatibility with 880 Series controls, guide tubes, and shielding allows NDT service providers to upgrade without retraining crews or replacing existing equipment. QSA Global designed, tested, and manufactured the 1100 Gamma-Ray Source Projector to meet ANSI N432-1980, ISO 3999:2004(E), IAEA SSR-6 (2012 & 2018), USNRC 10CFR34, 10CFR71, and 49CFR173 to ensure safe, compliant operations in field environments. ## 1100 Features for Safer, Simpler Operation - ![1100 Field Replaceable Lock Operate](https://5014511.fs1.hubspotusercontent-na1.net/hubfs/5014511/2024/1100/1100%20Field%20Replaceable%20Lock%20Operate.webp) Avoid Downtime from Lock Failures The new lock has a field-replaceable core that RSOs can swap out on-site, keeping the 1100 in service and inspections on schedule. A larger lock slide with improved position identification and side access helps radiographers confirm lock status and shutter position at a glance. - ![1100 Front Plate Indicators](https://5014511.fs1.hubspotusercontent-na1.net/hubfs/5014511/2024/1100/1100%20Front%20Plate%20Indicators.webp) Make Confident Connections Color-coded CONNECT, SECURE, and OPERATE front plate indicators guide radiographers through guide tube connection. Better side access at the rear plate and improved lock slide visibility confirm that the source is securely locked and safe before exposure, reducing misconnect risk and operator dose. - ![1100 S-Tube Ilustration](https://5014511.fs1.hubspotusercontent-na1.net/hubfs/5014511/2024/1100/1100%20S-Tube%20Ilustration.webp) Get Twice the Service Life Get twice the service life with a new S-tube design with improved, thicker tubing, and optimized geometry. The 1100 includes a 3-year S-tube warranty to help you avoid unplanned capital expenses and workflow delays from premature replacement. - ![Side view of the gold 1100 gamma ray source projector](https://5014511.fs1.hubspotusercontent-na1.net/hubfs/5014511/2024/1100/1000%20source%20projector%20side%20view.webp) Enjoy Lighter Weight Weighing an average weight of 46 lb (20 kg) with the jacket, the 1100 is under the 50 lb limit for one‑person carrying. Radiographers can carry and position the projector themselves, reducing the need for added crew members and improving access to confined spaces ## Specifications: 1100 vs. 880 Delta | Specification | 1100 | 880 Series Delta | Notes | | --- | --- | --- | --- | | Weight (with jacket) | 46 lb (20 kg) Average | 55 lb (25 kg) | 7 lb (3.2 kg) lighter and safe for one-person operation. | | Max Source Activity | Ir-192 (Model A426-1): 150 Ci (5.55 TBq) Se-75 (Model A426-2): 150 Ci (5.55 TBq) | Ir-192: 150 Ci (5.55 TBq) Se-75: 150 Ci (5.55 TBq) Yb-169: 108 Ci (4.00 TBq) | Same max source activity for Ir-192 and Se-75.
