{"title":"Counts.Pro capable","description":"\u003cp\u003eCounts.Pro is a measurement recording system that converts your current meters into devices far more capable than anything available at a fraction of the price. CHP Consultants developed the Counts.Pro datalogging system to fill the need for verifiable measurements in the lab or the field. The Counts.Pro uses a transmitter embedded in your existing count rate meters, a data collection Application (App) utilizing iOS devices (Apple iPhone, iPad, or iPod), and a Cloud data sharing and\n\u003cbr\u003earchive solution. The Counts.Pro App connects wirelessly to your current radiation meters and provides a real time digital display of the meter readings on iOS devices. Data, that in the past was only visible to the operator and not recordable, is now easily recorded and stored for sharing, detailed review, and analysis. Counts.Pro collects, stores and shares your measurements without requiring\n\u003cbr\u003especial software to calibrate or access the information.\u003c\/p\u003e","products":[{"product_id":"counts-pro-turns-your-meter-into-a-mobile-lab","title":"Counts.Pro - Turn your meter into a mobile lab","description":"\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUpgrade your current radiation meters with Counts.Pro.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/youtu.be\/pkDozLViUBg\"\u003eWatch the video\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eCounts.Pro is a hardware upgrade to existing radiation ratemeters that connects your meter into an Apple (IOS) device using Bluetooth LE and the Counts.Pro App. It digitizes and logs the output of up to two channels of your existing meter inventory. Each channel can have a preset alarm point as well. Each recorded measurement is a continuous recording taken in quarter-second intervals of your entire survey or scaler count. Counts.Pro captures every count your meter measures. Counts.Pro doesn't change the output of the meter, it revolutionizes the collection of data by recording the entire survey.

If you are taking boundary surveys, older iPhone or IPad with a low cost sim card is a great way to utilize the GPS with high accuracy on a budget. Low cost phones and iPads with cellular capability are available on Ebay. Disposable SIM cards can be bought for $15.

The digital LCD can present either the count rate data or be switched over to read the scaler counts. It has a rich array of logically arranged discrete controls on the front panel that permit precise control of the desired measurement. Control functions available include, decade range selection, scaler count time, power on\/off, response setting, LCD analog\/digital switch, PHA window switch, lamp, audio divide by, audio volume, count zeroing, scaler start\/halt. The wide range high voltage supply supports a wide variety of detectors with additional threshold and window settings that facilitate switching between gross counts and the energy band. The instrument housing is cast aluminum with a separate battery compartment and accompanying metal handle. This design delivers industrial robustness, quality, capability, and versatility that is difficult to surpass anywhere.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"margin-top: 0; margin-bottom: 0;\"\u003e\u003cspan style=\"color: #000000;\"\u003eThis meter is great for industrial use and with the Scaler function is a fantastic all around meter for performing all sorts of surveys and even counting samples.

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.

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.

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.

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\u003cul\u003e\n\u003cli\u003eOn the App Screen while running:\u003c\/li\u003e\n\u003cli\u003eCount Rate\u003c\/li\u003e\n\u003cli\u003eActual number of counts (Scaler)\u003c\/li\u003e\n\u003cli\u003eElapsed Time\u003c\/li\u003e\n\u003cli\u003eSettings for count times (including infinite)\u003c\/li\u003e\n\u003cli\u003eStart\/Stop button\u003c\/li\u003e\n\u003cli\u003eIn the Data file (collected when you run a count time):\u003cbr\u003eDate and time of EACH measurement\u003c\/li\u003e\n\u003cli\u003eActual counts in 0.25 second intervals with time stamp\u003c\/li\u003e\n\u003cli\u003eRunning count rate\u003c\/li\u003e\n\u003cli\u003eTotal Counts\u003c\/li\u003e\n\u003cli\u003eElapsed time\u003c\/li\u003e\n\u003cli\u003eGPS location (if enabled) - 3rd party GPS units can be bought to give sub-meter GPS to iOS Devices.\u003c\/li\u003e\n\u003cli\u003eThree user defined fields of unlimited length including the ability to take in measurement notes of observations.\u003c\/li\u003e\n\u003cli\u003eMeter and probe model and serial numbers\u003c\/li\u003e\n\u003cli\u003eEach count is stored on your device and can be emailed or shared using your smart device.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWe have installed these in Ludlum Meters, Bicron Meters, Thermo Radeye's, and other count rate meters.
