When activated, Stannic Chloride is a white colorless gas with a pungent odor. It fumes strongly in moist air forming white hydrochloric acid fume. The emitted tin compound has a strong odor that will provoke an involuntary reaction (i.e. coughing) by the test subject.

An affordable meter for measuring sky brightness for astronomers! The "Sky Quality Meter" measures the brightness of the night sky in magnitudes per square arcsecond. Designed by Dr. Doug Welch and Anthony Tekatch, the Unihedron Sky Quality Meter offers unprecedented sensitivity in a handheld meter. Uses: -Find out how good the night or site REALLY is. -Compare the sky brightness at different sites quantitatively. -Document the evolution of light pollution in your area. -Set planetarium dome illumination to mimic the skies people are likely to experience elsewhere in the city. -Monitor sky brightness through the night, night-to-night, and year-to-year. -Determine which nights show the greatest promise for finding the 'faintest fuzzies'! -Calibrate the effect of sky brightness on qualitative measures such as the Bortle Scale. -Investigate how sky brightness correlates with the solar cycle and month-to-month sunspot activity. -Help provide local ground truth for future sky brightness prediction with the Clear Sky Clock. -CCD users can make a correlation between the SQM reading and when the background reaches some ADC level. Features: -Audible signal while measurement is in progress. -Sky brightness displayed in visual magnitudes per square arcsecond. -Infrared blocking filter restricts measurement to visual bandpass. -Temperature in both Celsius and Fahrenheit as well as model number and serial number can be displayed with different button press sequence. - Precision readings at even the darkest sites. - Power-saving features designed in for maximum battery life. - Reverse battery protection. Specifications: -The Half Width Half Maximum (HWHM) of the angular sensitivity is ~42Â° -Operates from 9V battery (included). -Size 3.8 x 2.4 x 1 in. -Maximum light sampling time: 80 seconds. -Specifications are subject to change without notice.

Finally a Mold Test Kit that test for mold in your air like the professionals so. My Mold Detective's Mold Test Kit utilizes the same air sampling methods that industry professionals use to test air quality in homes and businesses and utilizes industry-standard air sample cassettes. My Mold Detective's Mold Test Kit is not just another petri dish sampling method that is outdated technology and unreliable, it is professionalism boxed and brought to the Do-It-Yourself populace in a simple 3 step process. Now you can stop ignoring the musty odors, allergic reactions and occupant complaints, and give the air you breathe the attention it deserves.
The Series CDW Wall Mount Carbon Dioxide/Temperature Transmitter combines accurate CO2 measurements with a passive temperature output. The Non-Dispersive Infrared (NDIR) sensor continuously updates the calibration through a proprietary logic feature which limits the amount of error due to drift. The CDW series is ideal for building automation systems to help control the fresh air intake in a room.
