I.Overview
HZ1 43 4 SF6 gas pu ri ty analyzer is the late st inte lligent me asur in g
in st rument dev eloped by our company. Th is pr oduct adopts the co lo r
hi gh li ght LCD touch screen as th e man-machine inte rface, the full Chinese
in terf ac e is convenient for op er atio n, and all kin ds of dat a ar e displayed in
real time. Th e full to uch screen with hig h pr ec is io n and fas t response is
us ed as man-m ac hi ne input, and a varie ty of fun ct io ns can be sw itched
freely. Buil t in hi gh -capacity rec ha rgeable lithi um ba tt ery pack provides
ul tra long standby time. Th e standard USB int erfa ce is co nfigured, and th e

The instrume nt adopts the mos t advanc ed mi cr o ther mal con du ctivity
sen so r with te mp eratur e compensation to pr ovide us ers wi th a simple
on -site de tection method of SF 6 pur ity. It is mainly used to measure the
pu rity (perc entage con tent ) of SF6 ga s in bottled SF6 gas, SF6 switch and
ot her equip ment . It can also be us ed in appli cati on s with several
ba ckgrou nd gases (special requir ements ar e req ui red) .

IV.Operation steps
1. Start up an d wa rm up for ten min ut es. Thi s pr oc es s can eliminate the
in fluence of ambie nt temper ature on the test results .
2. Connectin g SF6 equipme nt
a) Connect the th readed end of the measurin g pipe with the switch
con ne ctor and tighten it wi th a wrenc h;
b) Then in se rt one en d of the qui ck connector on the test pipe into the
sam pl ing por t on th e puri ty instrument - < gas inle t >;
c) Connect the ex ha ust pipe to the air outle t - < gas out le t >.
3. Check the power

When us in g DC powe r, please check th e battery po wer displayed in the
up pe r rig ht corn er. If th e pow er is less than abo ut 20%, please tur n off and
con tinue to use af ter charging.
4. Start mea sureme nt
Fir st, ope n the meter to me as ure th e needle va lve on the pipe, then adjust
the flow valve on the panel of the puri ty te st er, adjust the flow to about
0. 5L/M, and start measuri ng the puri ty value of the SF6 ga s.
5. Store dat a
After the equipment measurement is compl eted, the data can be sa ve d in
the instrum ent, and press the "data quer y" key to ca ll out the ope ration
menu.
6. Mea su ring other eq ui pm en t
After one equipment is measured, close the needle valve on the measuring
pi pe li ne and th e regulat in g valve on the pu rity ins trum ent. Re mo ve the
ad ap ter from th e SF6 Ele ctrical equ ip me nt . If it is nece ss ary to cont in ue to
mea su re other eq ui pment, conti nu e to mea su re the nex t eq ui pm en t
ac cord ing to the abov e steps.
7. End of measureme nt
After the measuremen t of all eq ui pm en t, turn off th e pow er supply of the
pu rity instrume nt.
V.Matters Needing Attention
1. The inst rume nt shall be placed in a safe pos it ion to pre ve nt damage.
Avoid violent vibration.
2. Do not de tect corrosive gases.
3. When adjusting th e gas flow, the fl ow va lve sha ll be opened slowly to
mak e the flow indi cati on withi n the range of 0.5 ~ 0.8 L / mi n.
4. The instrum ent shall be char ge d in time before us e. When ch arging,
ju st inser t the po wer adapter of the instrument in to the charging po rt

10
without turning on the powe r swi tch of the instrume nt. The inst rume nt will
cha rge automatically. Th e char ging time generally takes more than 5
ho ur s.
