Rechargeable Differential Pressure Meter - tc168

tc 168 1 02

This digital differential pressure meter has a built-in lithium battery. This instrument is designed with imported pressure sensor, high accuracy ADC and low power consumption MCU, professional high accuracy, high resolution, large screen display, with indoor temperature measurement. A single channel can quickly measure the current detection pressure value (relative to the current atmospheric pressure), and through dual channels can simultaneously detect the difference in pressure between the two detection ports (P1-P2).

  • Carbon dioxide concentration
  • Temperature
  • Humidity
  • Public places

The densely populated place such as meeting room, classroom, exhibition hall, hospitals, department stores, bars, hotel, air port, railway station and entertainment hall, etc. the carbon dioxide detector may be used for ventilation control and environment quality monitoring So, it is used to guarantee body health.

  • Agriculture

The carbon dioxide may be used for plant photosynthesis. Therefore, it is widely used for agriculture. The air fertilizer with proper concentration may improve output of agricultural crops. When the concentration of carbon dioxide is not sufficient, air fertilizer may be used. It will give great help for whether the vegetable growth or improvement of vegetable.

  • Animal husbandry

The air quality concerns healthy growth of animals. If the air is turbid for a long time and the concentration of carbon dioxide is high and ventilation is not provided, the animal will get ill or epidemic disease may burst out. Therefore, installation of carbon dioxide detector at livestock farm may prevent occurrence of animal epidemics.

  • Industry

The carbon dioxide detector is widely used in the Industry such as wastewater treatment, factory building, workshop, temperature, cleaning room, production safety and all types of Industries. Especially, it is very necessary to monitor the carbon dioxide in borehole operation. The carbon dioxide detector is used generally in metal processing, paper pulp and paper making, cleaning and solvent extraction as well as lower temperature cleaning and carbon dioxiderelevant Industry.
