Sitescan D20+
The Sitescan D+ Series of ultrasonic flaw detectors deliver high performance and advanced features, via an ergonomic and user focussed interface design. Enhanced menu navigation scroll-wheel enables fast navigation through functions via the menu structure, designed to guide the user through their tasks, with operation quickly becoming second nature. The Sitescan D20+ uses a broadband amplifier together with several narrow bands for improved perfomance, together with a square wave pulser and a Time Corrected Gain feature. Ideal for a spectrum of NDT applications including weld inspection, corrosion testing, castings and forgings and delamination checking.

Sitescan D20+ Overview
The Sitescan D20+ features ground breaking ergonomic design which has been evolved to make it comfortable for day-long use. The high resolution TFT VGA colour display has not been sacrificed giving the Sitescan D20+ one of the highest display to size ratios of any field instrument, providing high visibility at any light level.
Navigation
Using the new 3rd Generation Scroll wheel on the Sitescan D20+ allows for fast, single handed menu selection and setting changes. An upgraded, user centred, keypad has an increased resistance to water and improved tactile keys. Direct Access Keys enable fast access to essential parameters such as gate adjustment and gain control whilst unique user buttons can be assigned directly to menu items or actions that selected by the operator.
Robust and Adaptable
Sonatest's reputation for robust design and proven reliability is an important aspect of flaw detector ownership. Down time is expensive and should be minimized to ensure maximum productivity. The Sitescan D+ Series is constructed to high standards using engineered polymers and sealed to IP67, and is designed to incorporate many features to make site work easier.
The integrated pipe stand is adjustable to give easy positioning, whilst the standard camera mount fixing on the back opens up a wide variety of useful accessories such as magnetic hooks, tripod mounts and body harnesses. The Sitescan D20+ can be easily attached to pipe work, metal plates or hung from the nearest fixing, giving the user both hands free for scanning.
SDMS Lite (Data Management Software)
This Windows based data management tool interfaces the Sitescan D+-series to a PC. The Lite version comes as standard, allowing the capture of the currently displayed Ascan and transfer to Microsoft Word. This is useful for producing application notes or reporting indications. The optional full version uploads and downloads panel settings and A-scans, which can also be transferred into Microsoft Word for customised reporting. Thickness readings can be transferred into Excel for more advanced analysis such as charts for B & C-scans.

Body Harness
This unique body harness gives the end user the opportunity to work hands-free with the Sitescan D+ series units. The patented harness design has been developed considering both function and good carrying ergonomics and is very lightweight.
The wide shoulder plate, with body centred positioning, will make the carrying of the Sitescan D+ unit a joy for the user. The harness itself is very stable but can be supplemented with a waist strap if the work task involves a lot of movement and is easy to take off and store. This body harness is ideal for extended periods of use and the front plate is adjustable to fit all back lengths.
