EZ3505sc Chloride Ion-Selective Electrode (ISE) Standard Addition Analyser, 1 stream, 4x mA

EZ3505sc Chloride Ion-Selective Electrode (ISE) Standard Addition Analyser, 1 stream, 4x mA
Product #: EZ3505.9700140T
Unit Price Contact Hach

Advanced Standard Addition Technology

Ensure reliable data accuracy with advanced discontinuous and standard addition modes. This feature automatically compensates for interferences, delivering precise results even in complex or changing water conditions. Avoid compliance risks caused by inconsistent or unreliable measurements.

Designed for Low-Maintenance Operation

Frequent manual calibration and sensor cleaning increase maintenance effort and downtime. The EZ3505sc employs discontinuous and automated standard addition modes to compensate for matrix effects, stabilise potentiometric response, reduce reagent consumption, and maximise analyser uptime for reliable chloride monitoring.

Seamless System Integration

Isolated data silos hinder effective plant management. Featuring standard analogue and digital communication protocols, this analyser integrates easily into existing plant networks. Real-time visibility ensures you can make informed decisions quickly based on current process conditions.

Cost-Effective Scalability

Monitoring multiple sample points traditionally requires significant capital investment. This system supports multi-stream functionality, allowing a single unit to analyse up to 8 sample streams. You gain comprehensive process insight while optimising infrastructure costs and reducing equipment footprint.
