PH 100S ORP Transmitter for Industrial

Electronet Series pH-100S is an industrial-grade pH / ORP transmitter designed for accurate and continuous online measurement. It accepts input from any standard pH or ORP electrode, making it compatible with all major electrode brands.
The transmitter converts the signal into a standard 4–20 mA output (with optional HART). An LCD display provides real-time pH / ORP indication, while Zero/Span adjustments are easily accessible. Its user-friendly pictograph interface and rugged construction make it suitable for demanding industrial environments.
