Nikon Coolpix 800 digital camera with fish-eye lens
-
A super wide-angle of 180 degrees gets everything in the frame – great for giving
context.
The distortions resulting from such a wide angle can be used to artistic or humorous
effect.
Combine the incredibly short focal length with a small aperture, and even objects
touching the lens can be in focus.
A huge field of view combined with a relatively small camera means you can get very
unusual perspectives on small or inaccessible spaces.
A fisheye lens lets you easily capture full spherical panoramas in just a few shots.

LI-1400 Data-logger with Radiation Sensor and Photometric Sensor
The LI-1400 is a multipurpose data-logger that functions both as a data logging device and a
multichannel, auto-ranging meter. It can be configured as a hand-held meter to display
instantaneous data, or be configured to automatically log data over an extended period of time.
The LI-1400 has three current input channels are located on sealed BNC connectors, the BNC
connectors can be connected either the Radiation Sensor or the Photometric Sensor to
measure the data, the data are stored in the build-in memory, and it can be transferred to a
computer for analysis using the RS-232 interface.

Testo 400 and Testo 480 Climate Measuring Instrument
The testo 400 and testo 480 is a measuring instrument for measuring climate-related
parameters. The testo 400 and testo 480 is ideal for comfort level measurements for the
workplace evaluation and flow measurements in and at ventilation and air-conditioning
systems. Depending on the measurement parameter to be measured, certain probes or sensors
must be plugged into the instrument.
You can customize measuring programs to match the relevant measuring task (e.g. continuous
or punctual measurement). These measuring programs are linked to a specific measuring point.
After the measurement, the relevant measurement protocols are saved under the measuring
program.
There are the probes and sensors connected to the Testo 480:
-
The temp/RH probe.
The wind velocity probe.
The mean radiation sensor.
The 3-function probe for testo 400 only (temp/RH and wind velocity).

Wet and Dry Blub Thermometer
Dry Bulb Temperature of Air (DBT
The temperature of the air measured by the ordinary thermometer is called as the dry bulb
temperature of air, commonly referred as DBT. When ordinary thermometer is exposed to the
atmosphere, it indicates the dry bulb temperature, which is nothing but the atmospheric
temperature.
Wet Bulb Temperature of Air (WBT):
The wet bulb temperature of air is also measured by the ordinary thermometer, but the only
difference is that the bulb of the thermometer is covered by the wet cloth. Temperature of the
ordinary air measured by the thermometer when it is covered by wet cloth or wick is called as
the wet bulb temperature, commonly referred to as WBT. When the air comes in contact with
the wet cloth it absorbs some moisture and gives up some heat, sue to which the temperature
of the air reduces. This reduced temperature measured by the thermometer is called as the wet
bulb temperature.
