Chlorine Dioxide Gas Concentration Measurement Device for Sterilization Equipment Weraser Meter

Chlorine Dioxide Gas Concentration Measurement Device for Sterilization Equipment Weraser Meter

The command center for space disinfection! Measurement of gas to emission completed in 18 seconds!

The gas in the sterilization room is drawn into the measurement cell, and the ultraviolet light from the ultraviolet light-emitting diode is received by a photodiode. Concentration conversion is performed. Before measuring gas concentration, a zero point measurement is conducted with fresh air, and a light filter is inserted for K-point correction. After these calibrations, the gas concentration is measured. The measured gas is then discharged. This operation can be completed in [18 seconds]! *For more details, please download the PDF or feel free to contact us.

Water-related IoT: Water Quality Management System (Oil Concentration)

Water-related IoT: Water Quality Management System (Oil Concentration)

■■ Cloud service for automating water-related operations ■■

Water (drain) discharged from air compressors and air dryers contains oils such as compressor oil. Discharging drain that contains oil directly into the wastewater can cause environmental destruction and violate related laws (Water Pollution Prevention Act and Sewerage Act). Additionally, it can lead to problems such as uneven painting due to drain during air blowing, corrosion of piping, and failures of air equipment such as cylinders and solenoid valves. ■ Discharge regulation values under the Water Pollution Prevention Act: Oil concentration (n-hexane extractable substances) must be below 5 ppm. Measurement data can be viewed and managed in real-time on client devices (PCs, smartphones, tablets), which can help improve the efficiency of water quality management operations. ▶▶▶ For more details, please download the PDF ◀◀◀

Non-contact liquid concentration meter "PIOX(R)S"

Non-contact liquid concentration meter "PIOX(R)S"

Measurement of fluids in pipes regardless of acids or bases.

"PIOX(R)S" is a non-contact liquid density meter that can measure the concentration, density, and mass flow rate of corrosive fluids without contact. The measurement method is based on the principle of ultrasonic propagation time. Two ultrasonic sensors are installed from the outside of the piping, alternately transmitting and receiving ultrasonic signals. By measuring the time difference in propagation between the two ultrasonic signals, the flow velocity (v) is determined, and the volumetric flow rate is accurately calculated from the internal diameter of the piping. 【Features】 ■ Beneficial for plants ■ Corrosion-resistant ■ No risk of leakage from measuring instruments ■ No friction parts ■ No pressure limit *For more details, please download the PDF or feel free to contact us.

Inline Oxygen Concentration Meter "PNA Series"

Inline Oxygen Concentration Meter "PNA Series"

Energy-saving, space-saving, and pipe-saving! The oxygen concentration under pressure has become visible.

The PNA series is an inline oxygen concentration meter that uses a limit current method. When a voltage is applied to the zirconia element, an ionic current flows with oxygen ions as the carrier. As the oxygen concentration changes, the current characteristics also change proportionally, allowing for the detection of oxygen concentration. This method is durable and has a long expected lifespan. We also have a catalog with detailed specifications available. For more information, please download the PDF document below. 【Features】 ■ Switchable display for oxygen and inert gas concentrations ■ Upper and lower limit switch output settings and analog output available ■ Self-diagnostic function included ■ Protection structure equivalent to IP65 ■ Pressure-resistant structure *For more details, please refer to the PDF document or feel free to contact us.
