We make our best effort to provide you with high quality products in a short lead time followed by good customer support.
TEKHNE Corporation is the dew point sensor manufacturer in Japan. We have over 35 years’ experience in this field.
High quality products, short lead time and good customer support are the our basic policy.
We can be your best consultant and provide you with solutions against your problems with moisture control (dew point, moisture, absolute humidity, mixing ratio, etc.).
We’ll offer most suitable sensors, analysers or equiments to you, considering the amount of moisture, the kinds of gas, the pressure level, and the accuracy of your dew point measuring needs.
The dew point temperature is the temperature at which the air can no longer “hold” all of the water vapor which is mixed with it, and some of the water vapor must condense into liquid water. For example, if we cool the air around us down to 10 degree and some water vapor starts to condense into liquid water, that is “this air’s dew point temperature is 10 degree”.
In industrial and semiconductor manufacturers, sometimes they have to deal with gas whose dew points are as low as -80 degree, for example. It means that the level of moisture in the gas or air is so low that when the temperature is at as low as -80 degree, condensation starts to occur. Many people might be more familiar with relative humidity as humidity and moisture measurement unit, but just like the word “relative” itself explains, it indicates how much influence the temperature gives to the humidity level. On the other hand, dew point is not influenced by temperature and it shows absolute value of the amount of moisture in gas. To measure dew point, you need to have a sampling system with the most suitable instrument to your needs which is connected to plumbing directly.
All the TK-100 series dew point sensors are equipped with 4-20mA analog output as a standard. If the data needs to be logged, you can simply connect TK-100 dew point sensors to your logger.
TK-100 dew point sensor is durable with several kinds of corrosive gas. Please contact us for more detailed information.
In a dusty environment, we recommend customers to use filters in a plumbing so that dusts would be removed from the sampled gas before it is measured.
Yes, it does. When there is a pressure, the dew point will be displayed higher than an assumed value, and vice vers We are preparing good caliculation software. Please contact us to get it.
We recommend Teflon tubes or SUS tubes for measuring low dew points over -40deg C. In the case of measuring high dew points, since condensation is highly influential to the accuracy of the measurement, temperature control for the pluming will be required (e.g. heating up the sample plumbing, etc…) . Silicon and vinyl chloride are not suitable materials since these tubes tend to absorb and permeate moisture.
We always have several TK-100 in stock so that we can dispatch them as soon as possible. For more detailed information, please contact us.
We have a traceble standard dew point transmitter in our technical center so that we can conduct calibration in Japan.
The Calibration Laboratory of TEKHNE Corporation has gained accreditation by the JCSS(Japan Calibration Service System), whose accreditation standard is JIS Q 17025 (ISO/MEC 17025), as an MRA compliant operator in the category of humidity measurement in the range from -70 to -10 deg C dew point (accreditation number 0272). JCSS is operated by IA Japan signatory to APLAC (Asia Pacific Laboratory Accreditation Cooperation) and ILAC (International Laboratory Accreditation Corporation).
