## Overview

The SEI Inspector USB Handheld Digital Radiation Detector is a cutting-edge device designed for professionals to survey and monitor ionizing radiation levels in various environments. With features like a sensitive thin wall GM tube, USB connectivity for data management, and a long-lasting battery, this detector ensures you stay informed and safe from potential radiation hazards.

## Description

S.E. International Radiation Alert Inspector USB has built in efficiencies for common isotopes to calculate activity in Bequerels and DPM. It is optimized to detect small changes (low levels) in radiation levels and to have high sensitivity to many common radionuclides. The new back lit display shows readings in your choice of counts per minute (CPM), counts per second (CPS) uSv/hr, mR/hr, or in accumulated counts. The SEI Inspector USB counts ionizing radiation changes, and the unit of measurement is selected and displayed using the mode switch. The display shows various indicators, based on the mode setting, the function performed, and remaining battery power. These include low battery, alert, timer, total mode calibration mode, utility menu (timer, calibration, alarm set mode), and units of measurement. Reading ranges: 0.001 (1&muR) to 100.00 mR/hr, or 0 to 350000 CPM, or 0.01 to 1000 µSv/hr, 0 to 5000 CPS, total counts 9999000 µSv/hr. Calibration: Calibrated electronically using the free Observer USB software. Accuracy: MR/hr + or - 10 percent (NIST), + or -15 percent maximum 0 to 100, µSv/hr + or - 10 percent (NIST), + or - 15 percent maximum 0.01 to 1000, CPM + or - 10 percent (NIST), + or -15 percent maximum 0 to 350000. It has a factory default calibration reset option that will automatically reset to auto averaging, mR/hr, CPM, and CAL (calibration) 100. Energy sensitivity: 3340 CPM/mR/hr, referenced to Cesium (Cs) 137. Energy sensitivity detects alpha down to 2.0 MeV. It detects beta at 0.16 MeV with typical 25 percent detection efficiency at 1 MeV. It detects gamma down to 10 keV through the end window. It detects gamma and x-rays down to 10 keV typical through the window, and 40 keV minimum through the sidewall. GM tube: A halogen-quenched, uncompensated GM tube with an effective diameter of 1.75-inches. Normal background radiation: approx 10 to 20 CPM. The meter will hold at full-scale in fields as high as 100 times the maximum reading for anti-saturation. The meter is powered by a 9-volt alkaline battery (not included).

## Features

- Radiation detector used for surveying levels of potentially harmful ionizing particles and rays in the environment such as naturally occurring radioactive material (NORM) contamination
- Also use for and for gross wipe counting, contamination detection of packages, equipment and people, regulatory inspections, and for low energy radionuclide detection
- Free Observer USB software that allows you to download your data from the internal memory, set computer alarms, and calibrate your instrument; on board memory to collect accumulated counts
- Thin wall GM tube provides excellent sensitivity to low levels of alpha, beta, gamma, and x-rays; USB for use with observer USB software for PCs Battery: one 9-volt alkaline battery
- Red flashing light and a beep indicate each ionizing radiation event; battery life is approx. 2000 hours at normal background radiation levels; window thickness: 1.4 to 2 mg/sq cm

## Questions & Answers

**Q: Where is this meter manufactured?**
A: My understanding is that these devices are manufactured in Tennessee by a woman-owned business: http://seintl.com/about_se_international.html

**Q: Is there a user-settable dose rate alarm simlar to what the PRM-9000 has?**
A: Yes

**Q: Does this unit come with a conformance certificate  from factory?**
A: Yes it does. It certifies it was manufactured according to standards and was tested and verified it meets the standards. It warrants the calibration for 12 months.

**Q: The imi inspector and se inspector are two differen brands, but the products look exactly the same, the size, buttons, switches are all the same, why?**
A: They are definitely from two different companies.  Be aware the instruments are not the same.  Please contact IMI Customer Care if you have questions about the IMI Inspector V2.

### ⭐ The inspector failed to function at all when i used ...
*by T***Y on July 1, 2016*

The inspector failed to function at all when i used it the first time, I thought maybe it was operator error but come to find out it failed thesecond time as well, i will have to return it and hope they will replace it. ??

### ⭐⭐⭐⭐⭐ Everybody should have one!
*by H***E on November 16, 2014*

Best geiger counter unless you want to spend many times for for lab grade instrument. It’s pre-calibrated for Cesium 137 but the dose reading is pretty much a guess. Geiger counters really only detect disintegrations, not dose. You probably have no way of knowing what isotope is triggering the counter and unless it is only Cesium 137 you’ll get a misleading reading. That said this is one of the most sensitive meters you can buy. Normal background in my home is 30-35 CPM. I recently ran this meter over my 6 mo old furnace filter and it was reading 220-240 CPM. I put latex gloves and a respirator before moving the filter and sealed it in a heavy duty plastic bag before disposing of it.

### ⭐⭐⭐⭐ There is a catch for high altitude
*by T***N on May 18, 2014*

The large detector is great, but not usable at moderately high altitudes. If you are traveling above 8000 ft. altitude, the detector will break, so be warned. The other warning they do not advertise, but noted in the operator's manual, is that it will not work at temperatures over 100F. so don't try using it in Death Valley, midday during the summer months.It is a great instrument, but beware of prospecting for cool uranium minerals at high altitudes in the Eastern Sierra.I keep mine in an air-tight box when crossing high mountain passes.
