SWAS products and equipment systems

The standardized controller eliminates the need for multiple specialized controllers.

The multi-channel controller operates with 1 or 2 sensors, reducing investment costs and saving money when adding a second sensor later.

Plug-and-play with all Hach digital sensors.

This is a dual-channel controller with 4-20 mA signal outputs for transmitting primary and secondary measurement values.

New display and guided calibration procedures reduce operator errors.

Password-protected SD card provides a simple solution for data transfer and storage.

Visual warning system provides critical alarms.

Digital Communication:

• MODBUS RS232/RS485, Profibus DPV1, HART

The EZ Series Online Analysers offer multiple options to monitor Phosphate in water. Typical applications are wastewater, drinking water, steam & power generation, surface water.

The EZ1000 Series Analysers use colorimetric analysis to measure Phosphate:
– EZ1031 Vanadate yellow method; standard measuring range: 0.1 – 10 mg/L PO₄-P
– EZ1032 Molybdate blue method; standard measuring range: 0.005 – 1 mg/L PO₄-P

Options for EZ1000 analysers include:
– Calibration to 10, 25 or 50% of standard range
– Internal dilution

Options for all analysers include:
– Multiple stream analysis (1-8 streams) reducing cost per sampling point
– Analogue and/or digital outputs for communication

Phosphate can also be measured in combination with Total Phosphorus. For this option please check the EZ7800 Series.

Some applications may require the use of a sampling/filtration or an external dilution system for sample preconditioning. For this option please check the EZ9000 Sample Preconditioning page.

Hach’s new digital on-site analyser Phosphax sc LR with weather proof housing is ideal for the high precision determination of Ortho-Phosphate concentration directly at the tank. The instrument offers a wide measurement range for a variety of wastewater applications with detection limits as low as 0.015 mg/L PO₄-P and low response time including sample preparation. The Phosphate Analyser also features minimum reagent consumption and easy handling with analysis accessible at all times.

Online analyser for monitoring hydrazine and carbohydrazide oxygen scavengers.
An integral part of a complete water analytics system designed for the Power industry. A broad range of product options made to work together as flexible solutions meet your unique needs. The comprehensive approach saves you time on design, installation, training, maintenance, and operation.

Use only 2 liters of assorted reagents to perform continuous analysis for up to 90 days; Double that of the Silica series 5000 analyzer.

As an analyzer that uses a pressure compression system to dispense reagents, there is no need for an internal pump, minimizing maintenance needs.

Diagnostic tools including Hach’s exclusive Prognosys Technology, warning LEDs, and clear message display allow you to avoid unplanned downtime.

No more problems with reagents getting spilled in the equipment, the floor or on your clothes while fumbling with tubes and straws. With the improved design, now you just need to gently rotate the cap and straw into the sealed bottle containing the reagent to match the colors.

The input and output raw sampling feature allows rapid analysis of a sample poured into the analyzer and facilitates sampling from the analyzer for revalidation by laboratory testing.

Optimise Operation and Response Time with Automatic Electrode Reactivation
To maintain optimum response time and accuracy, the NA5600sc analyser provides automatic electrode reactivation. Reactivation uses non-hazardous chemicals and eliminates the need for manual reactivation or electrode etching.
