Overview
Enviro Testers’s industrial pH controller provides continuous online pH monitoring and control in harsh industrial environments with configurable outputs for digital or analog systems. Housed in a robust PC/ABS enclosure, it supports programmable auto-temperature compensation and ensures stable readings across -10 to 60 °C operation. The unit features both 4–20 mA analog and RS-485 digital (Modbus) output, ideal for integration with PLCs, SCADA, or DCS systems. Backed by OEM-ready customization, this controller is a versatile solution for diverse industrial processes.
Features
- Auto Temperature Compensation (ATC) for accurate pH measurement under varying temperatures.
- Dual Output Channels: 4–20 mA analog and RS-485 digital (Modbus) for flexible integration.
- Durable PC/ABS Enclosure rated for industrial usage in extreme conditions.
- Wide Temperature Capability: Operates from –10 to 60 °C (up to 100 °C in some variants).
- Storage Temperature Span: Robust storage from –20 to 70 °C.
- High Input Resistance Sensor Support: ≥ 1×10¹² Ω input workable.
- User-Friendly Calibration: Supports multi-point auto-buffer calibration (USA/NIST standards).
- Alarm Functions: Configurable high/low alarm relay outputs potentially available.
- OEM/ODM Customization: Logo, graphics, and packaging can be tailored per requirements.
- Compact Panel or Rail Mounting: Fits typical industrial panel dimensions (e.g., 96 × 96 mm).
Applications
- Water treatment and pH regulation in chemical, food, and beverage processing.
- Industrial effluent control, cooling towers, and boiler water conditioning.
- Environmental monitoring and neutralization systems.
- Integration into SCADA, PLC, and DCS platforms as part of smart industrial setups.
