Excellent geiger counter for the money.

I recently purchased the Monitor 4 geiger counter due to the ongoing nuclear crisis in Japan. I have been very pleased so far. It is very sensitive, accurate, durable and easy to use. Plus, the price is fair. I strongly recommend anyone who purchases this geiger to also purchase the Observer geiger software Radiation Alert OBSERVER Software For Collecting Counts From Radiation Detectors. When used together with the software, it turns the Monitor 4 into a very capable instrument. I have been using both together to check for low-levels of food and drink contamination. It has been very useful so far. I have also owned the Inspector+ geiger counter. That geiger counter has a super-sensitive pancake sensor. Only a 10-minute count is required for that instrument to get a fairly accurate reading of low-level contamination. BUT the same thing can be accomplished with the Monitor 4 when used with the Observer software. This can be done by taking a longer timed count of at least 20 minutes (but 30 minutes to 1 hour is even better). The reason the longer timed count is necessary is because the Monitor 4 has a much smaller sensor compared to the Inspector+. But in the end the same thing can be accomplished when used with the software. Plus the Monitor 4 is in stock NOW. The Inspector+ is back ordered everywhere by at least 6-12 months. You really can't go wrong with the Monitor 4 when used with the Observer software. It is a reliable, accurate, and durable instrument that will last many years. Just ask the owners of the older design Monitor 4.

Analog needle display not useful under ordinary conditions

The product is described as registering 5 to 20 CPM (counts per minute) "normal background radiation". This is how many clicks or beeps you'll get when you use the meter without any radioactive sample nearby, for instance if you are trying to detect food contamination. However, the analog needle display will not distinguish between these values. The most sensitive setting has the display read between 0 and 500 CPM, but at 5 CPM the needle will jump up a tiny bit and slowly drop back to zero after each particle is detected. You would need to connect the device to a computer in order to get such a sensitive reading. Such a reading would be made using software to count events over several minutes or an hour.It's nice that the meter has a headphone jack, which is a bit easier to interface a computer to than USB. It's also nice that the product specifications for the GM tube are more complete than other Geiger counters I've seen on Amazon. Just be aware that the needle display is not useful unless you happen to be around something that's really radioactive. Also, Geiger counters cannot be returned to Amazon, so you might be stuck with it.I wish that Amazon gave information about the sensitivity of the GM tubes in each of their Geiger counter products. I would like to find a counter which registers, say, 50 CPM for normal background radiation, using a larger tube window.

Geiger tube failed 2 months out of warrenty.

BEWARE OF QUALITY.Unit failed after 1 year and 2 months (just out of the one year warranty) and SE charged me full repair price ($150). It was a bad geiger tube. I had used it about 3 times (for about 5 minutes each time) over the course of the year. It was not subject to any environmental issues (I left it in the original box).

I seems to work

I am not sure if it is really accurated, I have not a ny instrument to make a quantitative comparison

Great item to detect alpha radiation not only beta and gamma for this price, and very fast to search higher spot, if you need to connect and calculate its data, i will recommend usb version of this, but it's enoght to check aroud our environment, here in tokyo, japan.

Budget detector that can still detect all three (alpha, beta, and gamma) types of radiation

Pro: cheaper than its brother (Inspector). Con: analog meter - have to count the "beeps" to measure CPM/accumulated readings.It seems the detector works (I'm not a radiation expert). I get background radiation 25-30 'beeps' a minute(CPM) here in SW US, and no significantly higher level was detected in the food that I've tested so far (wild salmon, squid, etc. from the pacific).I was cleaning up a closet today and found an old (20+Y.O.) gas lantern and remembered that some old filaments for those lanterns include radioactive material. The detector proved itself by showing 300+ CPM level (lower mR/hr for beta & gamma measures) on the filament. Obviously, the detector works!

Not for serious work - very low sensitivity

I purchased this device because I am working on radioactive isotope 32P (strong beta) extensively, and I want a personal device that measures me to ensure there is no contamination on me after work.First of all, it does count. However, it is not sensitive enough compare to a traditional Geiger counter with a pancake detector.I have compared side by side that when the traditional one used in the lab gives about 1.5k cpm, this Monitor4 does not show any difference compare to background, even when the detector is about 1-inch to the source.I am not sure about other application, for serious beta ray detection it does not work well.

Superior value and function

You will save a lot of $$ if you buy a modern instrument (like this one) vs an old CD 700 series meter, then have to get it refurbished and calibrated. While not as bulletproof as the old metal CD survey meters, this is new, it's calibrated, and in the long run cheaper.
