Wall Mount

ZGa21enc

  • Dual Beam NDIR (Non-Dispersive Infrared) technology is used to measure CO2 concentration up to 50,000 ppm (parts per million) and electrochemical technology to measure O2 concentration up to 30%
  • With the SEU (Sensor Unit) and RDU (Remote Display Unit), it can connect up to 3 RDU for safety notices
  • Large digital LCD display clearly indicates the ambient CO2、O2(optional) Concentration and Temperature
  • Relay output can automatically control a fan to ventilate confined spaces
  • Audible and Visual Alarm indications
  • IP54 Splash Proof Protection of SEU (Sensor Unit) except backside when installed on the wall

Introduction

  • ZyAura ZGa21enc, the Wall Mount CO2 & O2 Monitor, measures the CO2 concentration up to 50,000 ppm, O2 concentration for electrochemical technology and temperature. The gas meter also can control the related instruments easily, including the Sensor Unit (SEU) and Remote Display Unite (RDU) up to 3 connections, which is 8 meters long to extend your measure spot away from the display. The ZGa21enc relay output could control the other connected devices, such as CO2 generator or ventilation fan for the brewery, HVAC, metal and lightening industry.
     
    general intro
     

    Indoor Air Quality (IAQ) is measure for the quality of air in interiors, the comfortable indoor environmental quality can make people feel fresh, work efficiency and good for the health. The CO2 concentration is the important factor of good indoor air quality. People breath in oxygen and breath out CO2, nowadays people often close the windows to avoid noise and enjoy the comfort living and working environment provided by air-conditioning systems, which results in the fact that the indoor concentration of CO2 is far higher than outdoor average. With the high CO2 concentration and non- proper ventilation, people will feel headaches, dull, drowsiness, lose of concentration and correspond to the high levels of dust, chemicals and bacteria in the air.

    • CO2 Measurement Range: 0~50,000ppm (5%) display
    • CO2 Accuracy: ±100ppm or ±5% of reading, whichever is greater
    • O2 Measurement Range: 0~30% display
    • O2 Accuracy: Better than ± 3% of FS over 0.1 to 30%
    • Temperature Range: 0°C to 50°C (32°F to 122°F)
    • Temperature Accuracy: ±1°C(±2°F) when CO2 concentration is below first alarm level
    • Power Supply: AC adapter 110/220 VAC
    • Relay Output: Peak Current<2A@30VDC or 250VAC, SPDT for CO2 / O2
    • Operating Temperature: 0°C to 40°C (32°F to 104°F), 0-95% RH, non-condensing
