Why Electrode Material Decides Conductivity Sensor Lifetime Conductivity sensors are simple devices in principle: two electrodes, a driving voltage, and a current measurement. In practice, most of the maintenance burden in a water plant comes from the electrode surface rather than from the ... Read More

Suzhou, China — A New Digital Conductivity Sensor for Water and Wastewater Plants Daruifuno has released the DEC790, a digital conductivity sensor built on a graphite two-electrode measuring cell. The new model combines four selectable conductivity ranges, TDS and salinity measurement, automatic ... Read More

A Practical Buyer Guide to Digital ORP Sensors in Water Treatment Oxidation-reduction potential is one of the few measurements that tells an operator both what the chemistry is doing and whether the dosing system is actually working. Choosing a digital ORP sensor is therefore less about the probe ... Read More

DRH890 Digital ORP Sensor Now Available for Global Water Treatment Projects Our engineering team has released the DRH890 digital ORP sensor, a stainless steel 316 ORP probe designed for continuous oxidation-reduction potential monitoring in environmental protection water treatment, surface water, ...

ORP or Free Chlorine? A Practical Guide to Disinfection Control Every operator running a chlorination loop faces the same question: should the dosing pump follow a free chlorine analyser or an ORP sensor? Both are legitimate measurements, but they answer different questions, and confusing them is ... Read More

Installing a 1" NPT ORP Sensor: Five Mounting Methods and the Commissioning Checklist An ORP sensor is only as good as its installation. The same probe that reads steadily for years in a well-designed flow-through cell can drift continuously in a badly placed immersion bracket, and the cause is ... Read More

Daruifuno Launches DRH790 Digital ORP Sensor with RS485 Modbus Output [China, November 2026] — Daruifuno has released the DRH790 digital ORP sensor, a platinum-ring oxidation-reduction potential probe with native RS485 Modbus communication, IP68 sealing and a full ±2000 mV measuring range. The new ... Read More

System integrators evaluating a pH sensor spend most of their time on questions that have nothing to do with the glass bulb: which register holds the value, what data format it uses, how the station address is changed, and how calibration is triggered from a controller. Daruifuno has published the ... Read More

Wastewater treatment is the most demanding routine application for a pH electrode. Mixed liquor coats the glass bulb, sulphides attack the reference junction, and a plant that runs twenty-four hours a day cannot send a technician to the basin every week. Maintenance, not measurement, is where most ... Read More

Water treatment instrument manufacturer Daruifuno has introduced the DPH890, a digital pH sensor that outputs temperature-compensated pH and temperature values directly over RS485 Modbus RTU. The sensor is aimed at online monitoring points where an analog electrode plus a separate transmitter has ... Read More
