GasDNA Co.,Ltd is a professional and leading manufacturer of Fixed Infrared thermometers, Gas detectors and smoke detectors
for use in a various kinds of industries.
GasDNA is focusing on developing and distributing more convenient and stable gas detectors and infrared thermometers.
Based on the technologies and expertise accumulated for last 10 years, we have positioned as Korea's only infrared thermometer
manufacturer, and we are planning to expand into not only the domestic market but overseas markets.
We develop and manufacture efficient and reliable products based on state-of-the-art technologies, and we do our best to be the world's leading company in the gas detector and Infrared thermometer field.
We promise customer's safety and product quality in accordance with the quality assurance K mark and ISO9001 quality system to maximize the customer's use value.
Gas detectors detect one target combustible or toxic gas leaked from industrial sites for in order to prevent any accidents in advance. And it converts digital signal into the 4-20㎃ standard current signal for output signal which can be transmitted to various external devices such as PLC, DDC, RECODER, and so on. Using these functions, you can easily construct the gas monitoring system more extensive as well as more comprehensive.
Infrared thermometer measures a surface temperature by non-contact through measuring the infrared wavelength emitted from the target spot and converts it to standard current signal output (4~20mA) and RS-485 communication signal output. we have a various tempearture ranges upto 2400degreeC and compact and precision type, also can choose fixed and portable type.
