Counts.Pro uses a free App (iOS and Android) to record and share every count measured by any pulse generating radiation detector (GM, proportional, neutron, Scintillation). With Counts.Pro you can record your surveys for review and analysis, or take long term scaler counts to measure very low radiation level changes. Each data set includes every count measured by your meter, date, time, GPS, meter and probe info, operator inputs, and notes. Counts.Pro can measure 1 or 2 channels an includes an alarm feature for each channel.\u003c\/p\u003e\n\u003cp\u003eCounts.Pro (which is a top level domain for more research) allows you to record all your measurements and works with any detector, old or new, that measures pulses. Counts.Pro uses the GPS in your smart phone (which can be enhanced to provide sub meter GPS) to record location. Gone are the days when you only see a dancing needle on your meter and wonder what the true reading is. Data is stored in a .csv format which can be opened by any typical spreadsheet. You don't need special software to analyze what you get, so your files are \"future proof\".\u003c\/p\u003e\n\u003cp\u003eCounts.Pro gives you the following information:\u003c\/p\u003e\n\u003cp\u003eOn the App Screen while running:\u003c\/p\u003e\n\u003cp\u003eCount Rate\u003c\/p\u003e\n\u003cp\u003eActual number of counts (Scaler)\u003c\/p\u003e\n\u003cp\u003eElapsed Time\u003c\/p\u003e\n\u003cp\u003eSettings for count times (including infinite)\u003c\/p\u003e\n\u003cp\u003eStart\/Stop button\u003c\/p\u003e\n\u003cp\u003eIn the Data file (collected when you run a count time):\u003cbr\u003e\nDate and time of EACH measurement\u003c\/p\u003e\n\u003cp\u003eActual counts in 0.25 second intervals with time stamp\u003c\/p\u003e\n\u003cp\u003eRunning count rate\u003c\/p\u003e\n\u003cp\u003eTotal Counts\u003c\/p\u003e\n\u003cp\u003eElapsed time\u003c\/p\u003e\n\u003cp\u003eGPS location (if enabled) - 3rd party GPS units can be bought to give sub-meter GPS to iOS Devices.\u003c\/p\u003e\n\u003cp\u003eThree user defined fields of unlimited length including the ability to take in measurement notes of observations.\u003c\/p\u003e\n\u003cp\u003eMeter and probe model and serial numbers\u003c\/p\u003e\n\u003cp\u003eEach count is stored on your device and can be emailed or shared using your smart device.\u003c\/p\u003e\n\u003cp\u003eWe have installed these in Ludlum Meters, Bicron Meters, Thermo Radeye's, and other count rate meters.
