Parking area/garage Monitor(CO and NO), Controller

Model SA-PM100 

Navter's Parking Garage Monitor and controller is a wall mountable instrument that measures CO and NO2 concentration in air and controls the ventilation based on CO and NO2 concentration. It displays the real-time value of CO and NO2 concentration in ppm.

  • LCD display with real time values of CO and NO2 gas concentration.
  • Two dry contact relays for actuation of low and high speed blowers
  • Two cut off values, low level cut off for one relay and high level cutoff for second relay
  • Led indication of relay state on/off
  • Provision to change the cut off values based on user requirements
  • Real time continuous data logging of STEL (average of every 15 min.) & TWA (average of every hour).
  • The data log has auto generated gas concentration versus time
  • Analytical data of blower operation time and monthly energy savings.
  • Easy 2-step wireless connectivity
  • In Built storage of 1 million data records
  • Optional analog signal output
  • High efficiency sensor with quick response time
  • Optional network of monitor and controller units based on user requirement.
  • Wall mountable device.
  • Easy installation and usability

The clean room monitor has automatic data logging of STEL (short term exposure limit) values every 15 minutes throughout the operation of the monitor. It has inbuilt storage of 16GB that can store more than a million data records. The data log stored in the device can be easily accessed from any Wi-Fi enabled device such as smartphone, pc, laptop etc. The data log has auto generated graph of dust particle concentration versus date & time.

Cross sensitivities:

The cross sensitivity of various chemicals substances that affect the CO gas and NO2 gas readings is given below.

 

Substance

CO - Cross Sensitivity (%) NO2 - Cross Sensitivity (%)
Hydrogen 40 <-1
Nitric oxide <50 <20
Ethanol <0.5 <1
Ethylene <80 -
Nitrogen dioxide <7 -
Hydrogen sulphide - <40
Sulphur dioxide - <-1
Ammonia - <-1
Carbon monoxide - <-4
Toluene - <3
Chlorine - 100
