how often does the tester need to be calibrated and how much does it cost to calibrate

Per Corentium customer support (support@corentium.com), I was told "for our digital radon monitor there is no need for a recalibration within the lifetime of the instrument." I am not affiliated with this company and do not own this unit, but I had emailed them previously out of my own curiosity.

I have never calibrated mine and not sure how you would do it short of sending it back to factory. I have compared mine with several other test sets and also the system at my pool store and found it to be very accurate.

It comes with a year calibration. It is best to replace after a year and it comes with a certificate.

The only calibration I have seen happens during each power-on. The directions ask for a vial of clear pool water and it self calibrates.

No calibration required. It counts reflected light pulses. I've had one for some time with no issues and I use mine on a daily basis. I'm a marine diesel technician, I put reflective tape onthe vibration dampner reads every time. I had compared it to more expensive photo TACHS from snap-on and Mac and this one is dead on every time.

It is factory calibrated at the time of manufacture. If you need current calibration that must be done when purchased. Some retailers offer calibration for an extra fee or you can send it out to your local calibration shop.

This pH meter goes from 3 to 8, although if I remember correctly it does not claim accuracy above a pH of 7. There is no calibration required. However, since it depends upon the slight electrical signal generated by the electrodes in damp soil the cleanness of the electrodes is very important. They basically need repolishing before every measurement. That is done using a special polishing tape (Think ultra fine sandpaper, but do not use regular sand paper is it would damage the electrodes). I do wish they supplied more of the policing tape but more can be ordered. Accuracy depends upon cleanness of the electrodes, slightly damp soil (not wet), and if you water the soil to accomplish this you actually need to let it soak in for a couple of hours. Failure to pay attention to those details will alter the readings. I found this out when I failed to let the soil sit for a few hours and got one reading (6.5) and then sent off a soil sample and was told it was 7.3. I hope that helps.

It self calibrated when I first set it up. I have moved it twice since then with no problems.

Yes, it will. Make sure the battery (in the tester) is fresh, and the electrodes on the tester are clean.

I don't calibrate the meter. It works right out of the box for humidity level. I do not use the ph meter or the light meter. May be you can stick in in vinegar and see if it reads about 3

get some calibration solution and then dip the meter in it, hit the calibrate button then use it after it says saved

Interesting question. You might try the Taylor site. My past experience has been that the calibration isn't correct if it is replaced. My friend upgraded to this unit when his failed. I will probably follow suit. http://www.amazon.com/gp/product/B00EHNH3JC/ref=oh_details_o05_s00_i00?ie=UTF8&psc=1

As I recall the calibrates when you tap the platform with your foot and let it settle. You need to do this whenever the unit is moved.

We recommend getting it calibrated at a rate of about every 6 months, though it may continue to give accurate readings for longer than that.

Short answer is yes. The software will 'remind' you to calibrate after a month or so. It's good to regularly calibrate as monitors and settings can change over time. This is especially important if your work requires a calibrated monitor for print/video.

I have purchased two of these and both were in perfect calibration out of the box. One is still new but the other one has been working well and has held calibration for 10 months. If you do want to have calibration capability all you need is a 500 gram weight. a nickle weighs 5.1 on both of mine and a dollar weighs 1 gram even.

We have this test meter for our community well. We fluorinate according to the EPA guidelines. It works well when it is calibrated. You have to have the 1% fluoride solution and the tabs to calibrate the meter. We had the meter for about 4 months and the sensor went bad. The company replaced it immediately at no cost but with the wrong part. It took several weeks to replace it with the right part. It was on B/O for some time. Now that we use it daily I can get an idea of the level we need to be at. It's a field test and they are not 100% but close enough for what we need. When our levels were low the meter just gave a Lo code. It am not confident it would give you a zero reading you may be looking for. We have this test meter for our community well.
