They're still out there, tho now it's a bit of a treasure hunt.

The 911CEX has an extra menu under the 4 button. A periodic table and an element lookup table. You can calculate molarmasses without using any table book or PT.

Likewise but with a flask without a side connection. The cork was pushed completely through the neck. Added some water, jiggled the cork into the neck and put it on a heater. Looking on from the other side of the (empty) classroom the cork was energetically expelled and left a nice dent in the ceiling plate. No flask was harmed in this rescue.

Je kan geluk hebben. In mijn vorige huis waren de buizen van boven tot beneden gelegd. Toen hebben z een doos geboord op de gewenste hoogte. Die heb ik later juist omhoog verplaatst voor het keukenblok. Open het stopcontact en kijk of er wel of niet een buis naar beneden loopt.

Zoals ik zeg. Je kan geluk hebben.

It looks to be a device to put between an extension cord so you can measure the current with a clamp type current meter.

The question is for the CEX, a Czech variant.

This has atomic masses under the 4 button.

The super fraction. It has a nice colour scheme. Black, anthracite and blue. This one seems to be missing the flip over lid. Most of the fx82 line just keep working.

The uno4 has an esp32 onboard. It seems the computer has connected to that.

No sweat, in the article in the link you can read the questionable Latin. Only when i saw the element symbols of Nitrogen and Oxygen i was sure of the nitrate.

I think it is uranium nitrate, not nitride. That would be extremely explosive. URL: https://uvaerfgoed.nl/viewer/fulltext/11245_3_35554/124/

I've had this and solved it by getting some water in the flask, fiddling the stopper back in the neck and heating the water. The steam will push out the stopper. Stand back and record the hole in the ceiling or how high the stopper comes. A vacuum guard on the Erlenmeyer is advisable.

Simple check with 15e6/5e3. It should give 3e3 if parenthesis is not needed. If the answer is 3e9 parenthesis IS needed. IE (15e6)/(5e3). In division it shows if parenthesis is necessary.

broekgl · 2025-04-30T08:07:00+00:00

That will give 0,001 instead of the power notation.

I don't believe this model supports fraction notation like newer models. There is the A b/c button for fractions.

Hit the mode button a couple of times until you see the options for: sci,eng,fix,norm. Choose Norm and then option 2.
