Membrane Caps for HI76409 and HI76410 Electrodes (5 Pieces) HI76409A/P

Producer: HANNA Instruments

SKU: HANNA-HI76409A/P Category: Hanna experimental measuring equipment

Screw design

PTFE Membrane Cap

For use with HI76409 or HI76410 galvanic electrodes

Easy to refill HI7042S electrolyte

Purchase at:

The HI76409A/P are dissolved oxygen membrane caps designed specifically for the probe and galvanic sensor of Hanna's portable dissolved oxygen meter. The cap is made of ABS plastic with a HDPE membrane. The membrane cap is designed to be easily filled with electrolyte solution and installed onto the probe. The membrane cap separates the cathode and anode of the probe from the water being measured. Oxygen diffuses through the membrane and interacts with the galvanic system to produce a current that measures oxygen concentration. Each cap is designed to be easily filled with HI7042 electrolyte solution and screwed onto the probe.

HOW TO REPLACE MEMBRANE FOR ELECTRONS

PROPERLY STORE THE MEMBRANE WHEN NOT IN USE

HI76409A/P
Material	ABS plastic with HDPE membrane
Specifications	5 membrane caps with O-rings
Using	1. Rinse the HI76409A/P membrane cap with a small amount of HI7042S electrolyte solution, shaking gently while rinsing. 2. Place the O-ring in the correct position on the inside of the membrane cover. 3. Fill the HI7042S bottle with fresh electrolyte solution. 4. Use your finger to gently tap the edge of the membrane cap to ensure there are no trapped air bubbles. Do not tap the membrane directly from the bottom up to avoid damaging the membrane. 5. With the sensor tip facing down, screw the membrane cap onto the probe clockwise. A few drops of electrolyte solution will spill out to be exact.
Methods of preservation	– BStore membrane caps at room temperature, away from direct sunlight. – Do not reuse the old membrane cap after inserting it into the electrode. – Always use fresh HI7042S electrolyte solution – When not in use and during polarization, remove the membrane cap and discard the old electrolyte solution inside, then dry the probe and cover the probe with the red and black transport cap originally supplied.. THE ELECTRODE WILL OXIDATE AND BE COMPLETELY DAMAGED IF THE ELECTROLYTE SOLUTION IS LEFT UNUSED FOR TOO LONG TIME.
