Laser Moisture Meter Model 4010LX

Laser type! Responds quickly to concentration changes! The world's smallest installed TDLAS moisture meter.

● Successor model of the laser moisture meter Model 4010BR ● World's smallest compact wavelength-variable diode laser moisture meter ● Capable of measurement even with trace amounts of ammonia gas present ● Explosion-proof class Class I, Div I, Group B, C, D ● Equipped with data logger and sampling system ● Measurement at PPM levels ● Measurement time is just under 2 seconds (90% response) ■ Model 4010LX is suitable for moisture measurement under conditions requiring explosion-proof functionality, primarily in natural gas and petrochemical applications. Gas molecules such as saturated water vapor, oxygen, and hydrogen contained in process gas have the property of absorbing near-infrared light. The wavelength range at which gas molecules absorb near-infrared light varies by gas type, and by pinpoint measuring the wavelength range absorbed by saturated water vapor using TDLAS, it is possible to accurately measure the amount of saturated water vapor without being affected by other gas molecules. Additionally, the design has been revised to address the issues of high cost and the need for large installation space that were problems with conventional laser absorption spectroscopy, achieving miniaturization and lower prices. *For more details, please refer to the PDF document or feel free to contact us.*

About moisture meters in oil

Easy to handle! Enables 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 placing 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 basic calibration 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 calibration on-site if needed.
