Application
Application of 8693 AZ Long Tube pH Pen-Full Glass:
The 8693 AZ pH Meter could insert its 13 cm
long pH probe 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
0~14 to meet different Water Quality Testing applications.
The pH sensor electrode of 8693 AZ Long Tube Full Glass
pH Pen is protected/storage in a bottle, which could keep the pH
sensor wet. The 8693 AZ Long Tube Full Glass pH Pen
can be calibrated easily by one touch calibration function.
The 8693 AZ Long Tube Full Glass pH Pen has
big and clear LCD to show the real time pH and temperature value. The glass pH
electrode of 8693 AZ can be met with the
water solution pH measuring purposes of laboratory, water treated or food
treated processing industry testing object.
The 8693 AZ Long Tube Full Glass pH Pen was
being designed and manufactured by AZ Instrument, a well experienced
manufacturer for Environmental Measuring Instrument.

【FAQ of 8693 Long tube pH Pen (Round Tip)】
Q1: What is the best application for the AZ 8693 model?
A1: It is ideal for liquids in narrow-necked containers like test tubes or flasks where standard pH pens cannot reach.
A key advantage of the AZ 8693 is its all-glass electrode design, which provides superior chemical resistance against corrosive samples and ensures easier cleaning, making it highly reliable for laboratory and industrial chemical testing.
Q2: Is the 8693 easier to clean compared to standard pH meters?
A2: Yes. The smooth, non-porous surface of the all-glass stem prevents residues from clinging to the probe.
This is particularly advantageous when switching between different samples, as it minimizes the risk of cross-contamination and allows for thorough sterilization or chemical cleaning that might damage plastic-housed electrodes.
Q3: How do I maintain the long probe electrode for longevity?
A3: Always keep the glass bulb 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.
