TD40 Manual –revision 1.8 2
1. Introduction
1.1 Overview
The GlanAir TD40 measures particles from 0.35 to 40μm in diameter using a laser-based particle
sensor and pump-less air flow system. An LCD display provides on board display of PM1.0, PM2.5 and
PM10 values and wireless connectivity provides remote monitoring access for detailed analysis of PM
readings, real time particle size histograms as well as temperature and humidity monitoring.
The TD40 measures the light scattered by individual particles carried in a sample air stream through a
laser beam. These measurements are used to determine the particle size (related to the intensity of
light scattered via a calibration based on Mie scattering theory) and particle number concentration.
Particle mass loadings - PM1.0, PM2.5 or PM10, are then calculated from the particle size spectra and
concentration data, assuming a particle density and refractive index (RI).
1.2 Technical Specification
See glan-air.com/resources/
2. Sensor Operation
2.1 How it works
The TD40 classifies each particle size, recording the particle size to one of 24 software “bins” covering
the size range from 0.35 to 40 μm. The resulting particle size histograms can be evaluated using the
online web interface.
All particles, regardless of shape are assumed to be spherical and are therefore assigned a ‘spherical
equivalent size’. This size is related to the measurement of light scattered by the particle as defined
by Mie theory, an exact theory to predict scattering by spheres of known size and refractive index (RI).
The TD40 is calibrated using Polystyrene Spherical Latex Particles of a known diameter and known RI.
2.2 PM Measurements
The particle size data recorded by the TD40 monitor can be used to calculate the mass of airborne
particles per unit volume of air, normally expressed as μg/m3. The accepted international standard
definitions of particle mass loadings in the air are PM1.0, PM2.5 and PM10. These definitions relate to
the mass and size of particles that would be inhaled by a typical adult. So, for example, PM2.5 is defined
as ‘particles which pass through a size-selective inlet with a 50% efficiency cut-off at 2.5 μm
aerodynamic diameter’. The 50% cut-off indicates that a proportion of particles of larger than 2.5 μm

TD40 Manual –revision 1.8 3
will be included in PM2.5, the proportion decreasing with increasing particle size, in this case out to
approximately 10 μm particles.
The TD40 calculates the respective PM values according to the method defined by European Standard
EN 481. Conversion from the ‘optical size’ of each particle as recorded by the TD40 and the mass of
that particle requires knowledge of both particle density and its RI at the wavelength of the
illuminating laser beam, 658 nm. The latter is required because both the intensity and angular
distribution of scattered light from the particle are dependent on RI. The TD40 assumes an average RI
value of 1.5 + i0.
Notes
The TD40 calculations of particle mass assume a negligible contribution from particles below
approximately 0.35 μm, the lower limit of particle detection of the TD40 monitor.
The EN 481 standard definition for PM10 extends to particle sizes beyond the upper measurable size
limit of the TD40. In some cases, this can result in the reported PM10 value being underestimated by
up to ~10%.
3. Hardware Configuration
3.1 Requirements for Installing the TD40
The following is required in order to install the system:
•Access to a power connection
•Access to a wired internet connection for the gateway
•Once power is supplied and the data gateway is connected the unit will need to be added to
your online monitoring account. Please note that you only need to add the monitor device ID
to the online software.
•The monitor should be positioned within range of your GY36 gateway
3.2 Wireless Communication
The TD40 connects to the online monitoring system using Zigbee wireless communication. This
enables multiple monitors to be installed and communicate back to a wireless gateway which converts
wireless data to a single Ethernet point.

3.3 LCD Display
The LCD displays the current temperature and humidity and cycles through a view of each PM value
(PM1.0, PM2.5 & PM10) as follows;
Figure 2 → LCD Display
Note, there are variations in LCD output between the TD40 SKUs. The TD40-i8 provides bespoke
output for ISO-8 Cleanrooms with 0.5µm, 1µm and 5µm counts.
3.4 Where Best to Place the TD40
The TD40 continuously samples the air in its immediate vicinity, and throughout the day considering
the migration of air in a room will monitor a wide area around the device. However, for optimum
usage the system should be placed close to sources of particle contamination.
The unit can be wall mounted using the sensor enclosure mounting holes or placed flat on a desk or
worktop.
Note: Do not place the monitor upright on a desk as this will obstruct the flow of air to the
temperature and humidity sensors which are at the bottom of the unit.

4. Power Supply
The TD40 is supplied with a 12V DC power supply. The converter operates at 100 –240VAC on its input
and is compatible with the mains power network of most continents.
5. Internet Connection
5.1 Wireless Ethernet Gateway Connection
Your wireless monitor will need to be in range of the gateway which may be up to 30m depending on
the environment.
•To set up the Gateway please connect the Ethernet cable provided to the DATA HUB and then
connect to an Ethernet point or a spare Ethernet port on your router.
•Power on the device after connecting the supplied power supply. The device will power on
automatically and establish a connection with the monitor.
Please note: It can take up to 5 minutes for the gateway to pair with the monitor. You can check its
status by viewing the monitor’s dashboard for data arriving online.
5.2 Network Configuration
The DATA HUB will also by default automatically configure itself to your network settings using DHCP.

TD40 Manual –revision 1.8 6
It is possible to configure the monitor to connect to a static IP address. Please see section on Gateway
Network Configuration to complete this step.
6. Online Software Setup
6.1 Online Account Setup
To set up your online account to remotely monitor your IAQ monitor please navigate to
https://hex2.nuwavesensors.com/ on your computer internet browser.
On the webpage you will be prompted to sign in or create an account. As this is your first time to
