Apera Instruments LabSen 833 User Manual

LabSen electrochemical sensors are premium pH electrode with manufacturing technology
and key components imported from Switzerland. LabSen833 pH electrode adopts special HF
glass membrane, suitable for strong acid solution, or solution containing HF (≥3pH)
This probe has following features:
⚫ Impact-resist membrane (see the right picture), there is no danger of electrode
breakage during normal use.
⚫ Extremely long service life, able to measure solution containing HF for about
1000 times. (test condition: 25°C, 1% HF concentration, test period 1
minute )
⚫ Blue gel inner solution, does not flow and will not cause bubble.
⚫ Silver ion trap reference prevents the contamination of the junction when
testing sample contains sulfides and proteins.
