Swiss quality product. Designed for fine preparation work. Hardened needles, diameter 0.8 mm. Inside the shaft 3 spare needles are embedded. At the same time this knurled screw who embedded the spare needles is also the key to changing the needles. This holder is also manufactured with the usual precision and quality and cannot be dented.

This model has the option of real-time viewing, means the simultaneous transmission of measured values to an external screen.Power is supplied via the USB interface. The GAMMA-SCOUT ONLINE also offers (as the only model) the ability to evaluate the stored values via graphics tool. The storage as well as the ticker and the alarm function remain active during data output. The GAMMA-SCOUT ONLINE also contains all the features of the alert model.• ONLINE/ REAL TIME Function: The GAMMA-SCOUT can transmit both – the acquired pulses as well as the dose and dose rate to a connected PC at the same time as the measurement runs.• Graphics Tool: The Gamma-Scout ONLINE Model is the single one, which delivers a graphics tool in its software package for graphical evaluation of the measured values.• Threshold for Dose Rate: This model features an acoustic alert when radiation level exceeds a user programmed threshold.• Ticker: The user can set an acoustical ticker which activates with each gamma pulse detected.Further STANDARD Features• Easy Reading: In measuring mode ( button), the display shows the current radiation measurement reading every 2 sec. The display also temporarily shows the average H of the last day (24h, 12 am to 12 am).• Energy-Saving Constant Operation: The GAMMA-SCOUT® monitors radiation day and night and logs data for later download. The “RECHARGEABLE” model works with a rechargeable battery. When the GAMMA-SCOUT® is connected to a PC, the deviceis powered via the USB port. This protects and charges the akku.• Measures α-rays: Thanks to its LND sensor, Gamma-Scout measures α-rays in addition to β- and γ-rays.• Large Scale: GAMMA-SCOUT® is calibrated to measure across a wide scale (0.1 up to 1,000 μSv/h).• Tested Calibration: Each GAMMA-SCOUT® radiation meter is subjected to a final test. This test is supervised by the Institute of Radiation Protection; a state university for applied technology. The tested device must be within a confidence interval of 5% against a master, which in turn, is adjusted to a gauged reference Cs 137 emitter and the ODL.• Dose Rate and Dose: GAMMA-SCOUT® can be used as a dose meter (cumulative radiation).• Data Storage: GAMMA-SCOUT® stores all registered pulses in its internal memory and keeps them ready for you to use when desired. 32,000 readings: For constant monitoring, storage of environmental data is set at an interval of one value all 2 hours, which equates to 7 years of memory capacity. The user can set smaller intervals, which fills the memory capacity sooner.• Data Read-Out via Microsoft WINDOWS: The measured values can be read on Microsoft Windows (WIN 7 up to WIN 10)• Data Read-Out via MAC OS X: The measured values can be read on MAC OS X• Flexible Display: The dose rate may be displayed in sievert or Rem.• Allowed on flights: GAMMA-SCOUT(R) may be carried on board of airplanes.• Certification: GAMMA-SCOUT(R) meets also the American “FCC 15 Standard”.• Source isotope not equal to CS 137: The conversion of pulses per time into dose rate starts from the Cs 137. In the case that other isotopes are present, you can directly display the pulses per time and convert them to their own tables./* Style Definitions */table.MsoNormalTable{mso-style-name:"Normale Tabelle";mso-tstyle-rowband-size:0;mso-tstyle-colband-size:0;mso-style-noshow:yes;mso-style-priority:99;mso-style-parent:"";mso-padding-alt:0cm 5.4pt 0cm 5.4pt;mso-para-margin-top:0cm;mso-para-margin-right:0cm;mso-para-margin-bottom:10.0pt;mso-para-margin-left:0cm;line-height:115%;mso-pagination:widow-orphan;font-size:11.0pt;font-family:"Calibri","sans-serif";mso-ascii-font-family:Calibri;mso-ascii-theme-font:minor-latin;mso-hansi-font-family:Calibri;mso-hansi-theme-font:minor-latin;mso-fareast-language:EN-US;}Normal021falsefalsefalseDEX-NONEX-NONEUnhideWhenUsed="false" Name="Medium Grid 2 Accen
