Application
Application of 8552 AZ ORP Detector:
ORP stands for Oxidation Reduction Potential. The ORP is a measure of the
cleanliness of the water & its ability to break down contaminants, which is used
frequently in the water treatment, water disinfection process & food processing
industry.
The 8552 AZ ORP Pen can measure the
oxidation reduction potential value from -999mV to 999mV. It is powered by 4PCS
LR44 and carried easily. It could be met with the lab research or other study
purpose.
The 8552 AZ ORP Pen could be the Water
Quality Tester for the measuring purposes for Aquaculture, Aqua farm, swimming
pool, cooling tower, hot tubs or other related industry.
The 8552 AZ ORP mV Pen was being designed
and manufactured by AZ Instrument, a well experienced manufacturer for
Environmental Measuring Instrument.

FAQ AZ 8552 Affordable ORP Pocket Tester
Q1: Is the AZ 8552 ORP pocket tester accurate for daily use?
A1: Yes. With ±4 mV accuracy, the AZ 8552 pocket ORP tester provides dependable results for everyday ORP and water quality checks in pools, aquaculture, or treatment systems.
Q2: How does AZ 8552 compare to higher-cost ORP meters?
A2: While high-end ORP meters may offer tighter accuracy specs, the AZ 8552 is designed to balance performance and cost, delivering reliable readings at a competitive price.
Q3: What should I do if the ORP reading differs greatly from my previous measurement?
A3: If a large difference is observed, rinse the electrode with clean water and ensure it is fully immersed in the sample. Allow sufficient time for the reading to stabilize. Since the AZ 8552 does not support user calibration, it is recommended to verify the reading by comparing it with a fresh ORP standard solution (around 220–222 mV) to confirm proper sensor performance.
