Air Quality Testing - Indoor Digital Hand Held Meter CDM77535
The CDM77535 temperature-humidity-CO2 monitor is ideal for monitoring the indoor air quality (IAQ) of houses, offices, classrooms, factories, hospitals and hotels.
Indoor Air Quality Testing Meter CDM77535
Handheld Digital Environmental Meter is used for testing home, building, or office indoor air quality.
Air Quality Testing Meter Features:
- Measures Carbon Dioxide level, air temperature, dew point, wet bulb, temperature, and humidity
- View all three measurements simultaneously on the digital display of CO2 level, temperature and humidity
- Uses stable non-dispersive infrared (NDIR) sensor to measure CO2
- Calculates, periodically updates and displays 8-hour time-weighted average (TWA) of CO2 exposure and 15-minute short-term exposure limit (STEL)
- Backlit LCD
- Audible CO2 warning alarm
- Powered by batteries or included AC/DC adapter
- Manual calibration of CO2 and humidity
- RS-232 computer interface for uploading readings to a PC
- Minimum/Maximum memory + data hold
- CE and RoHS approved

Hi - Are there devices that measure pesticide vapor toxins? Not just the VOCs that propel, but certain known toxic ingredients some manufacturers use. thank you08/03/2020, 09:07 AM
We are not aware of any specific pesticide detectors that would not require lab testing.
