|
testo 435 family of instruments
can monitor and record critical Indoor Air Quality parameters
using wired and wireless probes
to monitor atmospheric CO2, air velocity, relative
humidity (dew point), temperature,
absolute pressure, differential pressure and illumination intensity.
This instrument
is ideal for
- taking velocity in
FPM (0 to 8,000 fpm),
- volumetric flow measurements
in CFM (volume flow calculation 0 to 999,999 CFM)
- temperature readings
(-58.0 to 300.0
°F).
- can average readings
over time or at a number of positions and
- easily calculate volumetric
flow in CFM, m3/sec, m3/hr, etc.

The
testo 521-526 series multifunction meter with the built-in micromanometer
is configured for differential pressure measurements in the HVAC
range of 0 to 40" wg (0-100 hPa), e.g. pressure drops across filters
or inspection of fans or extraction equipment.
The
meter has nine user
selectable display pressure units: in H2O, mbar, hPa,
bar, Pa, kPa, mm H2O, torr and psi. Flexibility is enhanced as
additional probes can be connected to testo 521-526 pressure meters
via 2 user defined probe socket.

The testo 535 is the easiest way
to measure CO2 for indoor air quality (IAQ) surveys. Poor air
quality in rooms can lead to tiredness, lack of concentration
and illness (Sick Building Syndrome) due to high CO2 concentration
(greater than 1000 ppm)
|
|
The testo 317-3
CO meter detects the presence of carbon monoxide (CO) in ambient
air from gas furnaces, water heaters, and other appliances or
equipment and signals the user of dangerous gas concentrations
with both visual and audible alarms.
|
|
The testo 545 light meter can quickly check lighting
levels and can quantify the luminous intensity in the workplace,
hospitals, offices or schools. It
can verify if the lighting meets specific minimum guidelines.
A location list with individual values can be saved and
later connected to form a curve using software.
This “light profile” provides information on
the uniformity of the lighting.

|
testo 625 thermohygrometer
simultaneously displays temperature and %RH or dew point - suitable
for monitoring work-area comfort conditions, IAQ parameters, HVAC
and manufacturing areas requiring humidity and temperature control.
Monitor for conditions that lead to mold/fungus growth. Probe
configuration options include using the probe head on a cable
and extended handle, and a wireless probe for locations which
are difficult to monitor when the system is operating.
