Moisture Analyzers TDLAS T-1 Series
Absorption spectroscopic dew point moisture meter The TDLAS T-1 series is the first domestic manufacturer to succeed in developing and commercializing a wavelength tunable diode laser absorption spectroscopic dew point moisture meter (TDLAS), and has the world's fastest response in the normal temperature and humidity range. It is a new product with characteristics. Can measure dew point from -70 to + 20 ° C DP.
Features
Highly reliable accuracy besides fast response
(Example) Dew point environment example Response time: -50 ℃ DP⇔0 ℃ DP Within 6 seconds (63% response)
Example of humidity environment Response time: 10% Rh⇔90% Rh (at25 ℃) 2 seconds (63% response)
Outstanding response suitable for immediate H2O measurement
It can be used in acid and alkali gases that could not be measured by many measuring instruments.
Dew point temperature measurement without the effect of supercooling
Provides accurate values without distinguishing frost and dew points that were problems with dew point meters.
Built-in pump for gas sampling
The vacuum pump necessary to draw the measurement gas to the instrument is built in.
Intuitive operation is possible
The vacuum pump necessary to draw the measurement gas to the instrument is built in.
monitoring on PC.
Free software included for logging and monitoring on PC.
Fast response by advanced technology.
Unlike measurement methods that permeate / absorb moisture, aggregate or deposit, water molecules are directly sensed, enabling extremely high-speed measurements. Comparison between TDLAS T-1 and mirror-cooled dew point meter (compared to our company).
TDLAS T-1 responds 90% within 6 seconds to a sudden dew point change from 0 ℃ DP to -50 ℃ DP. The dew point meter takes more than 15 minutes.

※1 By extending the pipe to be introduced into the main body and lowering the sampling gas temperature, it is possible to achieve a temperature higher than indicated.
※2 Accuracy in a stable environment (ambient temperature, sampling gas, etc.).
※3 Optional temperature sensor is required. However, it is possible to input and set a fixed value for calculation in the output setting.
※4 When the optional temperature sensor is not used, calculation is performed at the fixed sampling gas temperature set for calculation.
