Analyzer or sensor? Which one do you need
The sensor measures, the controller decides. The sensor reads the value in the process; the controller compares this value against the setpoint, generates an alarm, and drives the dosing pump or valve. What the market commonly calls an "analyzer" is often exactly this: sensor + controller. If you're looking for a "pH analyzer," what you actually need is a pH sensor paired with a suitable controller — we supply both together, matched to each other.
Choosing a controller doesn't limit your sensor choice: thanks to their universal sensor input and analog input, the Intuition-6 and Intuition-9 work with practically the full range of sensors on the market. The table below shows our recommended sensor–controller pairing for each parameter.
Recommended Sensor and Controller Pairings
| Measured Parameter | Recommended Sensor | Recommended Controller |
|---|---|---|
| pH / ORP | Hamilton EasyFerm Plus, Polilyte Plus, ChemoTrode · Walchem WEL/WDS | Intuition-6 · W100W · W600 |
| Conductivity | Hamilton Conducell · Walchem contacting and toroidal | Intuition-6 · W100W · W600 |

| Turbidity | Hefer TU-311 / TU-341 (loop-powered) | Intuition-6 · Intuition-9 · Hefer TSS-3000C |

You don’t need a separate analyzer for every parameter
Hefer sensors connect in two ways:
(a) Ready-made analyzer — PME electrode + its own controller: CL-3000-C (chlorine), CLO-3000-C (chlorine dioxide), O-3000-C (ozone), WHA-3000-C (hardness), OD-3000C (oxygen). One parameter, one box.
(b) Transmitter to a single hub — PME electrode + 2030 series transmitter (PH-2030 (pH), MV-2030 (ORP), C-2030 (conductivity), CL-2030 (chlorine / dissolved ozone)) generates a 4-20 mA signal; this signal connects to an analog input card fitted to the Intuition-6 or Intuition-9.
In other words, instead of four separate analyzers for four parameters, you get four transmitters and a single controller.
How many parameters will you measure?
- W100W — entry level, wall-mounted: conductivity and pH.
- Intuition-6 — 6 relay outputs, universal sensor input; expandable with analog, Modbus, and combination cards.
- Intuition-9 — 24 sensor inputs, 12 relays, color touchscreen; the same card architecture.
- W600 — network-connected; conductivity, pH, ORP, and disinfectant.
Card architecture: the Intuition-6 and Intuition-9 are modular — sensor input, analog (4-20 mA), Modbus, and combination cards are selected according to the application. This is why the controller can practically work with the full range of sensors on the market: any missing connection type is simply added with a card.
The W900 has been discontinued; the Intuition-9 replaced it.

Frequently Asked Questions About Online Measurement and Instrumentation
A technical guide to sensor selection, fouling compensation, Memosens digital technology, and automatic controller architectures.
How is the PTSA fluorometer (Pyxis ST-500) unaffected by turbidity and suspended solids in tower water?
The Pyxis ST-500 and ST-500SS probes use a proprietary multi-channel optical design. The device simultaneously measures fluorescence emission and turbidity scatter, mathematically compensating for background color and sediment interference. According to the manufacturer, measurement performance is maintained up to 100 NTU turbidity and/or 5 ppm iron, providing a stable tracer reading across the 0–300 ppb PTSA range.
Which process parameters can be managed simultaneously with the Walchem Intuition-9 controller?
With up to 8 direct sensor inputs and up to 24 analog inputs, the Intuition-9 controller manages pH, ORP, contacting/toroidal conductivity, dissolved oxygen (DO), free/total chlorine, corrosion rate (LPR) and flow parameters from a single screen. Blowdown valves, biocide pumps, and antiscalant dosing are closed-loop controlled through its 12 relay outputs.
What are the key differences between the Heyl Testomat 2000 and Testomat EVO?
The Testomat 2000 is a well-established, industry-standard water hardness titrator with 2 limit relays and optional 4-20 mA / RS232 cards. The Testomat EVO is the successor to the Testomat ECO, offering precision titration with a piston dosing pump, a graphic LCD, SD card data logging, and an RS232 serial interface; its 0.05–25 °dH range is selected according to indicator type.
What advantages do Hamilton Arc® / Memosens digital sensors have over conventional analog electrodes?
Hamilton Arc® sensors carry the microprocessor inside the sensor body, converting the measured analog millivolt signal directly into digital data at the sensor head. They are completely unaffected by moisture, cable length, or electromagnetic interference (motor/frequency inverter noise). Because the sensor also stores its calibration data in memory, it can be pre-calibrated in the laboratory and then installed on-site as a plug-and-play unit.
Does the Hefer WHA-3000-C ion-selective (ISE) hardness system consume reagents?
The Hefer WHA-3000-C and WHA-2000 work with a potentiometric ion-selective electrode (ISE) system: the signals of the hardness electrode and the reference electrode are sent to the controller. The manufacturer documents give no statement on reagent consumption; the sensor membrane can be damaged by free chlorine, ozone and organic solvents, so the sample is kept within the limits in the documents.
