Portable Carbon Dioxide Instrument

Portable Carbon Dioxide Instrument
Portable Carbon Dioxide Instrument
Product Code : P SENSE
Product Description

Model p SENSE is a low cost flexible and easy to use hand-held, instrument designed to measure the carbon dioxide concentration and temperature in surrounding air. The large illuminated display presents the 2 values simultaneously. Built-in data output (RS232) makes it simple to log data for longer time. Audible alarm is included . Max/Min Average as well as TWA and STEL measurements are also available. The carbon dioxide sensor's gold-plated infra-red waveguide and diffusion membrane filter pro- vides you great reliability, accuracy and long- term stability.

Features :

  • State-of-the-art non-dispersive infrared (NDIR) technology to measure carbon dioxide gas in parts-per-million (ppm)
  • Data output RS232
  • Displays the current carbon dioxide temperature on a large LCD
  • Displays TWA (8hours) STEL (15 minutes) Min, Max and average values
  • Internal automatic self-diagnostic function
  • Audible alarm
  • Easy to calibrate

Applications :

With a battery capacity covering more than 24 hours, the instrument works perfectly for diagnosing ventilation using carbon dioxide as the surrogate ventilation index.

The instrument works perfect for measuring the indoor air quality parameters CO2. Temp and Carbon dioxide has been acknowledged as a good indicator that adequate "fresh" outside air is being supplied to the occupants for acceptable indoor air quality. Adequate ventilation reduces temporary sickness, downtime and lost productivity.

The p SENSE is also ideal for measuring carbon dioxide concentration in incubators, greenhouses, mushroom farms, etc., where correct levels are essential for the process outcome.
