About moisture meters in oil

About moisture meters in oil

Easy to handle! Allows quantitative evaluation of moisture content in various oils! Easy maintenance!

1) Easy to handle Unlike the Karl Fischer method, no special techniques or reagents are required. With the handheld type, you can measure simply by inserting the probe into the oil. (It responds in 5 to 10 minutes.) With the continuous measurement type, by installing the probe in the oil flow path, you can continuously monitor moisture changes, which can be used for diagnosing oil contamination and degradation, ensuring you don't miss the timing for oil replacement. 2) Quantitative evaluation of various oils is possible When displaying in ppm conversion, we conduct analysis using the Karl Fischer method and set a conversion coefficient suitable for that oil. Therefore, even with ppm measurements, you can measure various oils while maintaining measurement accuracy equivalent to the Karl Fischer method. 3) Easy maintenance Customers can clean the sensor part themselves. We also provide a simple calibration kit, allowing customers to perform simple calibrations on their own. Repairs and calibrations, such as probe and sensor replacements, can also be conducted domestically. Our technicians can visit the site to perform calibrations on-site as well.

CO2 (carbon dioxide) sensor module

CO2 (carbon dioxide) sensor module

Achieving high gas selectivity and high precision with a single light source dual-wavelength NDIR (non-dispersive infrared absorption) method!

We introduce the 'CO2 (carbon dioxide) sensor module,' which has achieved a lifespan of over 10 years without calibration through the optimization of sensing intervals. By utilizing the fact that the infrared absorption characteristics differ depending on the type of gas, we have adopted a method that measures two wavelengths: the CO2 absorption wavelength and a reference wavelength. This module can be used for applications such as monitoring ventilation conditions, confirming the presence of people and animals, managing growth environments through the photosynthesis-promoting effects on plants like crops, and checking for the presence and freshness of vegetables in refrigerators. 【Features】 ■ Widely used for air quality monitoring ■ Adopts a method that measures two wavelengths: the CO2 absorption wavelength and a reference wavelength ■ Achieves high CO2 selectivity and high precision ■ Achieves a lifespan of over 10 years without calibration through the optimization of sensing intervals *For more details, please refer to the related links or feel free to contact us.

Wall-mounted/Desktop LED Display CO2 Alarm CO2GUARD 10

Wall-mounted/Desktop LED Display CO2 Alarm CO2GUARD 10

【No calibration needed for 5 years】A CO2 meter that displays CO2 concentration with color and sound, ideal for determining ventilation.

● The detection principle recommended by the Ministry of Economy, Trade and Industry is an optical sensor. ● Equipped with automatic CO2 calibration function (automatic correction function). ● High-precision measurement. ● Wall-mounted or portable tabletop placement. ● CO2 concentration displayed in color in stages from 0 to 5000 ppm. ● No maintenance required. ■ The CO2 Guard 10 accurately displays the surrounding carbon dioxide concentration as an indicator of indoor air quality (IAQ). By displaying CO2 levels with an LED, it helps determine the need for ventilation, such as opening windows. Proper ventilation and indoor air quality are very important for maintaining a healthy living and working environment. Maintaining good indoor air quality can reduce the risk of aerosol infections, such as the coronavirus, even in densely populated spaces. Additionally, ventilating based on CO2 levels can significantly reduce energy costs compared to irregular ventilation. For more details, please contact us or refer to the catalog.

The principle of the CO2 meter (carbon dioxide concentration meter).

The principle of the CO2 meter (carbon dioxide concentration meter).

The detection principle recommended by the Ministry of Economy, Trade and Industry for CO2 measuring devices is an optical sensor. It features an automatic calibration function (automatic correction function) and excellent long-term stability.

We have adopted a unique automatic calibration method (double beam NDIR method). As a result, it excels in long-term stability and maintainability, and the annual drift is kept very low at 20 ppm/year. Its reliability is proven not only through rigorous testing but also by its market share in Europe. Please choose from the duct-mounted EE850, wall-mounted EE800, or agricultural EE820. You can also select concentration scaling and output options. For more details on CO2 meters in general, please visit the URL below.
