Critical - Model Yesair -8-Channel Indoor Air Quality Monitor

Both models come with one temperature sensor, one relative humidity (RH) sensor and the capacity for 5 internal gas sensors consisting of a maximum of three electrochemical toxic gas or oxygen sensors plus two high current draw sensors such as an infrared, PID, catalytic or particulate sensor. Sensor readings, battery level and data logging status can be viewed live on the multi-line, backlit, LCD display.

The YESAIR is a battery powered, portable air quality detection and data logging instrument designed for intermittent or continuous indoor air quality monitoring.

Dust, spores, smoke, build-up of gas and/or gas emissions along with high humidity levels and inadequate ventilation can cause poor air quality inside buildings that can leave you vulnerable to severe respiratory health issues. You may already be suffering from asthma or allergies or recovering from a respiratory illness, all of which makes breathing difficult at the best of times. Monitoring the indoor air quality can:

• Identify the levels of indoor air contaminants
• Determine if fresh air intake to re-circulated air ratio is adequate
• Improve processes required to guarantee healthier indoor air
• Provide a log of readings for constant analysis so modifications can be made appropriately
• Increase comfort and productivity
• Reduce sickness
• Give you peace of mind

With the handheld, battery operated YESAIR Indoor Air Quality Monitor you can easily detect particles and gases inside buildings.

1. YESAIR Pump - draws in sample air through a nozzle with an internal pump on the top of the unit
2. YESAIR Diffusion - works by sample air passing through the sensor openings by natural circulation of air on top of the unit
3. YESAIR Dual Probe Incubator Verification - draws in sample air using the internal pump, through an attached temperature and relative humidity probe and high humidity gas probe. This model is specifically for C02 and 02 sampling in high humidity environments such incubator chambers and horticultural applications (greenhouses, ^ mushroom farms, etc).

Multi-line, backlit, LCD display shows sensor readings, battery level and data logging status. The YESAIR can reliably record time-based information, which can be downloaded via a USB port and the YES Viewer Software allows users to analyze and graph the data.

Equipped with Plug & Play Smart Sensor Technology, many of the sensors modules can be changed in the field and are operable within minutes. Choose from a selection of up to 30 different sensors to best suit your application specifications. In addition to the temperature and RH sensors, the YESAIR can handle up to 5 additional internal plug & play sensors consisting of a maximum of 3 electrochemical toxic gas or oxygen sensors, and 2 high current draw sensors such as an infrared PID or catalytic sensor, plus 1 externally mounted particulate sensor.

An optional gas sampling probe 3 is available with the Pump model. The probe has a 10 in / 25.4 cm wand and 30 in / 76 cm of tubing that fits onto the nozzle and allows you to reach into areas that are difficult to access.
