Dear All:
The oxygen level in NMR-Labs during refilling process of LN2 and LHe can
drop to a dangerous low mark; this item was discussed earlier here.
This is just to let you know that we've got an excellent 02 monitoring device:
It's quite handy (not much larger than a cigarette-box - if you remember),
you wear it on your belt.
It even works at strong magnetic fields. Battery and sensor work for a year
(and more) without exchange.
Its name is Micro III G203
For further information see: www.gfg-mbh.com
Ask for article No. 1 318 070 , that´s the iron-free version.
