Introduction
(업데이트예정)
1.1 Product Overview
The DA-770-CO,CO2 stands as a cutting-edge gas analyzer, renowned for its exceptional precision and unparalleled reliability within the Korean market. Through the incorporation of advanced sensing technology, it distinguishes itself with an extended operational lifespan and heightened stability in comparison to its counterparts. Remarkably, its primary focus centers solely on measuring Ammonia, thereby enabling precise readings even within environments fraught with explosive gases.
1.2 Product Description
The DA-770-CO,CO2 distinguishes itself by being comparatively less susceptible to temperature, humidity, and air pressure variations, setting it apart from alternative products dependent on electrochemical sensors. Additionally, it remains unaffected by the sample gas flow rate, eliminates the need for electrolytes, and demands less frequent calibration and maintenance efforts.
Features
Manual Calibration Function
This device can be calibrated as per requirement and types of gases. This device has very easy calibration process that makes the maintenance and operation easy. Calibration ensures that the gas detector maintains accurate and reliable measurements over time. It is typically recommended to calibrate gas detectors regularly
Built-in HD (High Resolution) A/D Converter
The device is equipped with a high-resolution analog-to-digital (A/D) converter, ensuring precise and accurate conversion of analog signals into digital output. This technology enhances the accuracy of the output signal, resulting in reliable and trustworthy measurements.
User Programming
The device allows users to customize various settings, such as the detection range and other functions, according to their specific requirements and preferences. This feature provides flexibility and adaptability to meet diverse monitoring needs.
Analog 4-20mA Transmitter
With the analog 4-20mA output, the device enables stable and long-distance signal transmission of up to 2.5 kilometers. This ensures reliable communication and allows for extended signal transmission distances while maintaining signal integrity.
Alarm Output
The device also features an alarm output capability. It is equipped with a Single-Pole Single-Throw (SPST) relay contact that provides a two-step alarm functionality. This means it can trigger two separate alarm states, denoted as alarm 1 and alarm 2, enabling effective alerting and response to gas detection events.
