Technical Specifications

The PH-J100 maintains exceptional accuracy with ±0.01 pH precision even in extreme pH conditions ranging from -2.00 to 16.00 pH. The integrated PT1000 temperature sensor provides automatic temperature compensation with ±0.3°C accuracy from -10.0 to 130.0°C.

The digital signal processing architecture ensures stable measurements free from electrical noise and interference, critical in chemical processing environments with heavy electrical equipment.

Connectivity and Integration

With its RS485 Modbus RTU interface, the PH-J100 seamlessly integrates into industrial SCADA systems and process control networks. The 4-20mA current output option ensures compatibility with traditional chemical plant controllers, PLCs, and safety systems.

The probe operates on 9-24V DC power supply, making it compatible with standard industrial power systems and intrinsically safe barriers where required.

Installation Notes

The NPT 3/4” threaded design provides secure installation in chemical tanks, reactors, and process piping. The chemical-resistant construction ensures long service life even in highly corrosive environments. The 5-wire/BNC connection maintains signal integrity in harsh chemical atmospheres.

Safety and Durability

The PH-J100 is constructed with specially selected materials that resist chemical attack from both strong acids (pH < 2) and strong alkalis (pH > 12). This ensures:

• Extended sensor lifetime in aggressive environments
• Reduced maintenance and replacement costs
• Consistent accuracy over time
• Safe operation in hazardous chemical processes

Process Control Benefits

Accurate pH monitoring in chemical manufacturing is critical for product quality, safety, and regulatory compliance. The PH-J100 provides the reliability and chemical resistance needed for continuous monitoring in the most demanding applications.
