Application
Application of 8695 AZ Flat Surface Long Tube pH
Detector:
The 8695 AZ pH Meter has 12.5 cm long pH
probe with flat surface electrode, which could be inserting to the container
with narrow opening size easily than other pH Meter. It has the waterproof IP65
function, and it can measure the pH value from 2~12 to meet different Water
Quality Testing applications.
The pH sensor electrode of 8695 AZ Flat Surface Long
Tube pH Pen is protected/storage in a bottle, which could keep the pH
sensor wet. The 8695 AZ Water Pen with Flat
Surface pH sensor can be calibrated easily by one touch calibration function.
The 8695 AZ Flat Surface Long Tube pH Pen
has big and clear LCD to show the real time pH and temperature value. The flat
bottom pH electrode of 8695 AZ can be met
with the water solution pH measuring purposes of skin, surface, agar plate,
food, paper, leather or mat Industry testing object.
The 8695 AZ Flat Surface Long Tube pH Pen
was being designed and manufactured by AZ Instrument, a well experienced
manufacturer for Environmental Measuring Instrument.

FAQ
【FAQ of 8695 Flat Surface pH Pen (Skin/Paper)】
Q1: Why use a flat electrode instead of a bulb?
A1: Flat electrodes like the AZ 8695 provide maximum contact on solid surfaces or with very small droplets (micro-samples) where a bulb cannot submerge.
Q2: Why is it necessary to dampen the sample surface before using the AZ 8695 flat pH pen?
A2: Since pH measurement requires an ionic exchange between the electrode and the sample, the AZ 8695 flat electrode needs a thin layer of liquid to establish a proper reading.
When testing dry surfaces like paper, fabric, or skin, you must first apply a drop of distilled water or a neutral saline solution to the surface.
This creates the necessary "liquid bridge" to ensure an accurate and stable pH measurement on solid materials.
Q3: How do I maintain the long probe electrode for longevity?
A3: Always keep the electrode tip moist by adding KCL storage solution to the protective cap. Avoid touching the glass membrane with hard objects and rinse with distilled water after each use to prevent cross-contamination.
