digital hydrometer: where?

[mmmrsia]

Hi,
Where can we buy a digital hydrometer for dry box or dry cab?
What is the current price and preferrably the cheapest that works.


thanks

[mmmrsia]

Is it really called hydrometer? Maybe it is humidity meter...

[mmmrsia]

Opps just found out...it is called HYGROMETER

[eagleray]

There is a shop at basement of Sim Lim Towers (not Sim Lim Square), cannot remember the name. Specialises in thermometers and hygrometers .... i got a small digital hygrometer + thermometer for about S$28

but have now reverted to a analog one ... as the digital one keeps running out of batteries every 6 mths or so

[sehsuan]

that's called Space Electronics.

they have stores at both SLS and SLT basements.

You can get it at Giant Hypermart too. The branch at Parkway has 2 models, going for around $30. With thermometer and hygrometer.

I am pretty interested in the analouge ones...

Seen them in Space Electronics too?

U can try buy digital hydrometer at those DIY shop...saw one b4, cost ard $39 if I nt wrong...

For me I am cheapo so I buy those cheaper anagloue type...cost $6.50 only... ..I buy those tat were actually intended for using in cars...1 package contain 1 thermometer and 1 hydrometer...pretty accuarte I tink...almost as accurate as the original digital hydrometer in my dry cabinet

for being cheapo~! ...I bought mine at the basement DIY at Causeway point.....there r a few types for cars actually but mine is the cheapest liao...

but a word of caution, I actually used it only to double check and back up my digital hydrometer....being so cheap, I nt sure it is durable anot....I used it for ard 2wks+ only....so if u only have this hydrometer may nt be very safe...so might as well invest in a better hydrometer...

Ok man.....I know which store liao...that DIY store at the basement.

I stay in Woodlands.....causeway point is just so perfect for me!

Thanks for the caution, I'm also thinking of getting one to back-up my current digital hygrometer.

Thanks alot man!!!

Thanks for the replies. Another question:

1. If your dry box is not see - through when you open it to check the hygrometer reading, will it change drastically/immediately once you open the box?
2. Is the ideal reading between 45-55?

thanks again.

I am using a digi-cabi 40L dry cabinet.

What happens to me is normally when I open the door, the RH readings start to increase quite fast.Can go from 45% to 70%, depending on how long the door is kept opened.

Once door is closed again, it will start to normalise again and drops to its original reading, plus minus 1 or 2% perhaps.......no big deal.......

The recommended reading for storing cameras and gears is abt 45% - 55%.

Hope this helps......

I might have mis-interpreted your question here.

If you are just opening to check the hygrometer's reading, that initial few secs of opening should not change your reading alot.

You might want to conduct a few "dry-box opening drills" to open in lightning speed......just kidding......

get digital 1, for accuracy.
my analog meter give mi a veri huge different.
(ie. A.M shows 65%, digital show 50%)

No Prob dude~!.. so u manage to find it?...btw u might want to try doing a salt test to check the accuracy of your hydrometer...my digital is off by ard 4% while the cheapo analogue one is only off by 1%... ....dunnoe why leh...haa

Yupz I agree wif eagles_creek on this...the digital hydometer on my cabi doesnt change immediately once I open the door...take ard 1-2 sec to react...so guess should be enough time for you to check ur readings..

the digital hydometer is already calibrated? Do we need to calibrate it again to confirm?

[jnet6]

i think cannot calibrate....

[Ah_Seng]

Yo scramblur11,

I really like that two mini-meters. Thanks for the recommendations.

Pretty neat man !!! "Stuck" it at the front of the drawers and it just makes my dry cabinet looks more cool......

Trying to have fun with $6.50......

The readings are only abt 2-3% difference between my digital and analouge.
And the thermometer is pretty accurate too!

Neat !!!

Did not do a salt test, but as long as the difference remains constant, it should be fine.

Then I realise that home-fix DIY store is also selling digi-cabi dry cabinet.40L for $148. $10 more than digital-point. They are also selling the 80L ones...two hundred plus......

jnet6 is right, I think the digital hygrometer cannot be calibrated. They are supposed to be calibrated in factory or something.

Tink there are some type of hydrometer tat can be calibrated...but the digital hydrometer in my digi cabi cannot calibrate..tink is cheaper ones...so u can onli do a salt test den roughly set ur settings...
