The Portable pH Dissolved Oxygen Meter (Model PD10) launched by DDKSCI is a compact device dedicated to pH and dissolved oxygen (DO) testing, with an additional mV measurement function. Widely suitable for multiple scenarios including environmental monitoring, industrial production, and agricultural cultivation, it makes water quality testing more efficient and hassle-free.
I. Core Function: Accurate Detection of Key Indicators
The main function of this device is to quickly test the pH value and dissolved oxygen content of liquids. It also has an extra mV measurement function.
- Environmental protection workers can use it to spot-check river water quality.
- Food processing factories can use it to test production water indicators.
- Hydroponic growers can monitor the pH and oxygen levels of nutrient solutions.
- It also meets the basic analysis needs of labs.
You don’t need to switch between different devices.This makes testing more efficient.
II.Core Advantages: Durable and User-Friendly
Strong Protection
The Portable pH Dissolved Oxygen Meter has an IP57 dustproof and waterproof rating, plus a silicone protective case. It can resist dust and splashes, so it’s good for use in damp workshops or outdoor testing.
Easy to Read and Operate
It has a 3.5-inch color screen with backlight. This lets you clearly see measurement results and stability. The interface is simple—even new users can learn to use it quickly.
Flexible and Convenient
It can store up to 3,000 sets of data. It has a Type-C charging port that meets the latest EU standards. The foldable stand turns it into a bench-top device. So it works for both portable on-site testing and fixed-location testing.
III. Key Technology: Reliable Data Accuracy
The Portable pH Dissolved Oxygen Meter has reliable testing precision, with the following key parameters:
- pH measurement: Range is -2.000–20.000pH, accuracy is ±0.002pH.
- Dissolved oxygen measurement: Range is 0–20.00mg/L, accuracy is ±0.30mg/L.
The device automatically adjusts for temperature changes between 0–50℃. For dissolved oxygen testing, it supports manual salinity adjustment and automatic pressure adjustment. This ensures accurate data in different environments.
IV. Frequently Asked Questions (FAQ)
Is the device hard to calibrate?
No, it’s not. For pH, you can do 1–3 point calibration. For dissolved oxygen, you can calibrate with 100% oxygen or zero oxygen. It comes with calibration solutions and a user manual. Follow the step-by-step guide, and you can finish calibration in 5 minutes.
Is the battery life enough for outdoor use?
Yes. It has a built-in rechargeable lithium battery. A full charge lets it work continuously for over 8 hours. You can charge it with a power bank via the Type-C port—so you don’t have to worry about running out of power outdoors.
How to export stored data?
Connect the Portable pH Dissolved Oxygen Meter to a computer with a Type-C cable. Use the matching PC software to export up to 3,000 sets of data. The exported data includes serial number, measured value, temperature and timestamp. This makes follow-up analysis easy.
The Portable pH Dissolved Oxygen Meter comes with a full set of accessories, including a pH probe, dissolved oxygen probe and calibration solutions. You can use it right after unboxing. With its accuracy, durability and convenience, the DDKSCI PD10 (pH/mV/DO Meter) meets the needs of many industries and is a practical choice for water quality testing.
