The RP-3000 is designed for the demanding needs of wastewater treatment, power plants, and chemical dosing systems.
The RP-3000 has fully isolated 4-20mA outputs, which means that electromagnetic interference from heavy gear like pumps and mixers won’t mess with your measurement results. This is different from ordinary meters. This analyzer is easy to add to your PLC or SCADA system since it has a vivid IPS LCD screen and an RS485 Modbus RTU protocol built in.

Innovative Application Scenarios
“Dual task master” for tough jobs
- Chemical business: It has two channels that check the pH and ORP of two reaction lines at the same time. It also has switches that add chemicals automatically to keep the process stable and cut down on the amount of work that needs to be done by hand.
- When making drugs, it’s important to follow GMP rules, keep an eye on the pH and ORP of clean water and preparation solutions, and give data that can be tracked.
- Food production: Keep an eye on the pH level of the water used to mix raw materials and clean to make sure the end product stays of the same quality and follows all food safety rules.
Outdoor warriors in harsh environments
- Municipal sewage treatment: with IP65 rating, able to prevent rain, dust, and moisture; Wall mounted installation saves space and continuously monitors wastewater pH/ORP to meet discharge standards.
- If you have a cooling tower, it can work in hot (up to 60 °C) and muggy conditions, check the pH level of the water that is flowing through it, keep pipes from scaling and rusting, and make equipment last longer.
- Rural water supply: It can be installed outside in towns and ponds and makes sure that the water is safe to drink by running steadily and needing little upkeep.
Flexible installation of ‘space saving solutions’
- Small laboratory and testing line: compact design, suitable for narrow control cabinets; And dual channel monitoring eliminates the need for multiple devices, saving space.
- Renovation project: Supports panel installation and wall mounted installation, making it easy to integrate into existing systems without major modifications.
- Mobile monitoring: Suitable for temporary scenarios such as emergency wastewater treatment and construction site runoff as a portable power source, with flexible and fast deployment.
Compliance Navigator with Data That Can Be Tracked
- Automatically record pH/ORP data for industrial wastewater to make records that can be used for environmental checks and avoid fines for not following the rules.
- Water supply network: Keep an eye on the pH level of tanks and transport pipes to find problems with the water quality quickly, stop pipeline corrosion, and keep people healthy.
- Aquaculture: Keeping an eye on the pH and ORP levels of water in fish ponds and using relays to change the aeration and doses to help fish survive.
