No reagents, no need for dilution, instant results, pollution resistant design, remote mobile phone or computer calibration, data recording and diagno
Product details
The Pyxis ST-600 series online sodium hypochlorite probe uses a uniquely designed optical structure to detect and analyze the UV absorption of high concentration (0.01% -16%) sodium hypochlorite solutions at different concentrations, thereby achieving online monitoring of the concentration and content of sodium hypochlorite solutions. The probe can be assembled into a customized tee, which has two three-quarters inch (DN20) NPT internal threaded openings for easy installation into the same three-quarters inch (DN20) water intake circuit. The sensor is powered by a 24V DC power supply, with 4-20mA analog and RS-485 Modbus digital output signals. This feature enables LR-736 to be suitable for most OEM microprocessor based controllers, PLCs, or directly connected to distributed networks. Calibration and wireless diagnosis can be performed through Upyxis Bluetooth connection on mobile phones.
The optical structure design of the ST-600 series online probe makes it very easy to clean, which can avoid the accumulation of impurities from affecting the measurement.
The ST-600 series online probe uses a shorter wavelength gallium phosphide photodiode, which greatly improves the reliability of the ST-600 series online probe and allows it to work in harsh environments for a long time.
Typical applications
Water treatment plants, medical disinfection equipment, sodium hypochlorite generators and other sterilization and disinfection occasions.
instrumentCharacteristics of the device
- Advanced optical monitoring method, no reagents, no dilution, instant results, long-term stable operation
- Pollution resistant design: Embedded quartz tube flow channel design, greatly reducing the need for cleaning and maintenance
- Sodium hypochlorite concentration can be calibrated based on sample concentration
- Built in transmitter, no need for preamplifier or header, directly outputs RS485 or 4-20mA isolated signal, more stable and accurate long-distance transmission
- Calibration, data recording, and diagnosis can be performed on personal computers or smartphones through Bluetooth/USB adapters
- Before leaving the factory, the probe undergoes pressure aging testing and pre calibration to ensure stability and reliability
- Standard IP67 aviation connector, can be directly connected to Pyxis UC-100/UC-1000 universal controller
- Standard 3/4-inch tee fittings are available, and various diameter tee fittings can also be customized to accommodate online installation of sodium hypochlorite conveying pipelines of different diameters
