The JIRS LP Series Low Pressure RO Membrane Elements deliver up to 99% stable salt rejection and high permeate flow at low operating pressure. Designed for brackish water desalination and pure water production in industrial, commercial, and drinking water applications.
The JIRS Residual Chlorine Sensor is designed for continuous online measurement of free chlorine and hypochlorous acid (HOCl) in water treatment processes. Built with an advanced constant voltage three-electrode system and a platinum working electrode, it provides stable and accurate readings across a 0–20.00 mg/L range with 0.01 mg/L resolution.
JIRS pH sensor series offers five industrial online pH combination electrodes — GP-100, GP-100T, GP-100 PTFE, GP-100T PTFE, and GP-400G — covering 0–14 pH measurement across 0–120 °C. Featuring gel electrolyte salt bridges, anti-fouling PTFE or ceramic diaphragms, and low-impedance glass membranes, these sensors deliver ±0.01 pH accuracy with 5-second response. Options include ABS, PTFE, or high-temperature glass bodies, with or without PT1000/PT100/NTC temperature compensation, for wastewater treatment, chemical processing, and corrosive environments.
JIRS GO-300 and GO-400G are industrial online ORP (Oxidation-Reduction Potential) sensors built for continuous water quality monitoring. Combining platinum measuring electrodes, gel-filled reference systems, and anti-fouling PTFE diaphragms, these redox sensors deliver fast 5-second response and long-term stability with zero electrolyte refilling. The GO-300 (ABS body, 0–60 °C) covers general wastewater treatment, while the GO-400G (high-temperature glass body, 5–100 °C) handles boiler water and chromium-containing wastewater.
JIRS PH/ORP-6800 industrial online ORP controller supports switchable ORP and pH measurement with matching sensor probe. It features dual high/low limit relays for automatic chemical dosing control, isolated 4-20mA analog output and optional RS485 Modbus communication. Built-in auto/manual temperature compensation, password lock, power-saving backlight and ESD overvoltage protection. This panel-mounted monitor fits wastewater, chemical, electroplating, printing, swimming pool and aquaculture water monitoring with multi-voltage power supply. Pre-calibrated at factory for long-term stable low-drift measurement.
EC/TDS-6800 Online Conductivity TDS Resistivity Controller | Industrial Water Monitor with Dual Relay Alarm, Isolated 4-20mA & Modbus RS485 Output, PID Control, Panel Mount Water Quality Transmitter for Pure Water, Wastewater, Food & Chemical Industry
JIRS CL-6850 is an industrial online free chlorine controller designed for continuous monitoring and control of free chlorine, HOCl, pH and temperature in water. Featuring a non-membrane constant voltage sensor, it requires no diaphragm or reagent replacement, delivering high sensitivity, fast response and low maintenance. Ideal for drinking water plants, swimming pools, bottling lines and industrial water treatment.
JIRS industrial online pH meter pH ORP controller features auto and manual temperature compensation dual high low limit relay alarm isolated 4 20mA output and optional RS485 Modbus to provide accurate real time water quality detection for electroplating chemical printing and wastewater industries.
JIRS EC/TDS-6800 is a single-channel online controller that simultaneously measures conductivity, TDS, resistivity and temperature with PT1000 auto compensation.
JIRS EC/TDS-600 online conductivity TDS controller is a compact panel mount industrial water monitor. With auto temperature compensation, dual relay alarm and isolated 4-20mA output, it supports optional RS485 Modbus and multiple matching sensors. Ideal for RO, hydroponics, cooling water and water treatment systems, customizable and OEM available.
LCD display with backlight, English operation interface.
Rotameter measures fluid flow based on the throttling principle. It changes the flow area of the fluid to keep the differential pressure above and below the rotor constant, so it is also called a variable flow area constant differential pressure flow meter, also known as a float flow meter.
