Truly amazing - speed,conv. and accuracy
on April 10, 2009
Bought this couple of weeks back consequent to my son developing high fever and which fluctuated considerably. This caused the Red Cross $9.00 digital thermometer useless as it takes approx. a minute (under armpits) to record temparature. Our doctor advised us to buy Braun based ear thermometer.
First off - there are quite a models available. After taking to doctor and doing research - the 2 new models are IRT 4520 and IRT 4020. These are EXACT copies (all functionality) like their PRO 4000 versions!
The ExacTemp feature has a pre-heated tip which is more comfortable for the ear.
The older models (PRO 3000) is about $80, but uses lithium batteries and I don't think has pre-heated tip.
Has a "sort of" battery meter. Starts to show - that battery's low, flashing means - will effect results. (Very good)
Switch on, place tip (with tip cover, without cover, doesn't work)
push START and WITHIN TWO SECONDS you get the temperature.
Notes: Slightly hold the ear in order to place the tip INTO THE EAR HOLE to get best INTERNAL EAR CANAL reading. The readings are stored for access later - total 8 memory readings.
Auto shut-off: 60 sec.
The storage is into a white canister type case, which has HORIZONTAL standing (not good - as VERTICAL standing would have been better or if provided ALSO - good).
The given 21 nos. of lens caps are very little. Thankfully, the whole package of lens caps goes INSIDE the thermometer case, storing them together.
Size-wise it's a bit thick and thus slightly problematic to carry along but due to it's accuracy/etc. worth the hassle.
The ejector is very useful. Just press it and the lens cap is THROWN forward. Be careful, it's literally EJECTED out. (Point towards garbage can - I hit my wife's nose...;)
If you get covers for the PRO 4xxx series - you can use it with IRT 4520. That's very good. The batteries are regular AA series and last long. The IRT 4020 has 1 extra feature - has a protective plastic cap covering the disposable lens caps. That's actually very useful. So, if you get 4520 and 4020 at approx. the same price, I would opt for 4020.
There are some calibrations possible, but advice you NOT to do so. If you keep pressing the I/O button even after OFF, then you can switch between Celsius/Fahrenheit settings.
You can set the optimal temperature of the tip, define ambient room temp, etc - Keep i/o button pressed, after OFF starts to FLASH, there will be loud beep - immediately release the I/O button. Then keep pressing (short presses) of the I/O to switch to go thru the options stated above.
Note: ALTHOUGH NOT STATED, IT'S ADVISABLE to have the thermometer calibrated professionally *KAZ, in US* annually.
Weight - about 8 oz.
Any diff. between ExacTemp and non-Exac?
Yes - the pre-heated tip.
Any diff. btw the Professional (+$200) and this?
NONE in functionality, the PRO's just more heavy duty, with anti-theft features, base-station, etc. (all sold as accessories)
Any diff. btw this and the "Compact" one?
Yes - this has ExacTemp, has Memory functions, overall - quicker.
Does the PRO series lens cover fit?
Difference with IRT 4520 and IRT 4020?
IRT 4020 has a protective cover ON top of lens cover. IRT 4020 - difficult to buy. Pro 4xxx series REPLICATES IRT 4520, not IRT 4020.
Very accurate. I compared with mercury-based prof. thermometers.
Use the SAME ear (you'll notice each ear records diff. temp) Hold the ear slightly up, push gently the tip INSIDE and press "Start"
Can I use it "orally", rectum, arm-pits?
I don't think so, it's gonna be difficult, the tip's designed for ears. Although stated possible - can't imagine how.
Any features I would have liked?
Yes, the following:
(a) Memory feature has the date/time included
(b) The memory feature has the LEFT ear and RIGHT ear set. (i.e. 2*8 memory locations, at least)
(c) Ability to switch off the BEEP
(d) A 2nd. display where the "Start" button is to see the temp. immediately (priority - low)
(e) More thin - the overall product
(f) Lens covers are very costly
(g) The case should be able to STAND, not lying down only
[UPDATE} 12/2012: Still going strong, absolutely no complaints. Traveled with us thru Europe and Asia and back to NA. Used gazillion times with zero failures or problems!
