    the sensor on mine is on the back side. i made another last night.

    just went and looked. one is ready 62% and the other is 66%. mine are working fine and jars even seem to be pretty airtight.

    jars appear to be losing a bit of the humidity, so i am going to glue the meters in.

    made 2 more tonight. a brand new sharp razor blade is the cleanest method of cutting the lids.

    I've come to the conclusion that mini hygrometers made by China are a joke to begin with.

    I have an Integra packet of 62% in the jar. After hours, the inside mini hygrometer is reading 54% and the mini hygrometer stuck in the lid reads 51%.

    Useless toys. Only cost me $5 for three of them.

    here's mine about 2-3 years old now

    I got the gauge local and simply inserted into the Chinese cookie jar lid

    is junky as but works well

    flip open the back to re trim the gauge

    I avoid glue as it will impart an after taste

    that won't go well with my organic weed ..lol

    good luck

    ps bic is for scale

    You got lucky if it reads accurate, compared to a reliable source. There are probably millions of mini hygrometers like these churned out. I guess I'm one of the unlucky bastards.

    aren't there some glues that would not leak vapor?

    In most cases inserting a gauge into a plastic lid

    can be easy done re ur prev post with drill and knife = easy

    if glue is required cause you misjudged the insert size

    a glue suitable for plastic maybe required

    most plastic glues have some chem that stinks to fuck

    as these chem glues dry by evaporation it may be several days before the stink is gone

    its called outgassing..?

    The fumes from CA (super glue) are a vaporized form of the cyanoacrylate monomer that irritate sensitive membranes in the eyes, nose, and throat. They are immediately polymerized by the moisture in the membranes and become inert. These risks can be minimized by using CA in well ventilated areas. About 5% of the population can become sensitized to CA fumes after repeated exposure, resulting in flu-like symptoms.[24] CA may also be a skin irritant, causing an allergic skin reaction. The ACGIH assign a Threshold Limit Value exposure limit of 200 parts per billion. On rare occasions, inhalation may trigger asthma. There is no singular measurement of toxicity for all cyanoacrylate adhesives because of the large number of adhesives that contain various cyanoacrylate formulations.

    My favorite way to cut a hole in plastic is to break just the tip off a #11 X-Acto knife blade and use the back side as a sort of graver using a metal straightedge as a guide- you'll have to make several passes until you break through the plastic. I'm a master jeweler btw

    Because after the glue cures it should be relatively benign unless you eat it or smoke it lol

    Lol theres lots more nasty stuff in the materials of your home.

    Just saying. .... and yes i know you dont smoke your wall paint

    Or the silicones and other sealants used in construction.

    thought about doing that. wood jig and dremel drill style cutting bit.

    however, the plastic lids i bought are a little fragile if you stress them.

    this is what works best. a couple score marks and it starts to go through

    Most mini hygrometers are set at the factory and can't be adjusted by taking it apart. As for the round ones that have an adjustment knob, 17% of Amazon buyers of that item said its junk (won't calibrate). My cheapo square ones aren't reading correctly at all now. 62% Boost packet inside jar, mini hygrometer inside jar and it reads 53% overnight. You'd probably get one in a hundred made that read correctly over time. And if they initially DO read correctly like mine did, that accuracy won't last.

    its true I screwed some of the earlier cookie jar lids maybe 2 ?

    but returned this time armed with the knowledge to get soft ...even flexible lids

    that can cut with a boxcutter or razor above

    in reflection I suppose the easiest safest glue would be Latex

    the organic tree sap from the rubber tree used as carpet glue

    if you don't mind the slight oder of Ammonia ..?

    lol

    Accuracy of my junky mini hygrometers..to me is acceptable within 10-15% ..12% being the most predominant? popular even

    the real deal is the liltle batteries cost a damm bomb here

    I've even tried to hook up other batteries

    to the pisstake of my buddies... grimmm!
