Dissolved Hydrogen Meter "HYA-120S/120P"

Temperature compensation circuit responds to temperature changes. Available in two types: inline and portable. This is a compact dissolved hydrogen meter that can be rented!

The "HYA-120S/120P" is a compact dissolved hydrogen meter with a diaphragm-type polarographic electrode. It has a built-in temperature compensation circuit, allowing for stable measurements even with sample liquids that undergo temperature changes. There is no need to bring the temperature of the calibration hydrogen gas close to that of the sample liquid. You can choose between two types: the "inline type," which can be installed in piping for real-time measurements, and the "portable type," which is convenient for use in laboratories. If you are concerned about the initial cost, short-term rental options are also available! 【Features】 ■ It adopts a relay with a large contact capacity for the output contacts, enabling direct drive of pumps and solenoid valves. ■ The depth is 126mm, making it possible to install in commercially available control panels. ■ High-brightness LED for easy visibility. * In addition to the "product catalog," we are also offering "technical materials" that explain the measurement principles! Please check them out via the download button. * Feel free to contact us for demo unit rentals.
