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 ~42° -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.

The Dwyer Rate-Master series RMC flowmeter is a 10" scale air flow meter that has 1/2" female NPT inlet and outlet connections for inline monitoring and measuring of air flow with an accuracy of + or – 2% of full scale for precise readings. An integral flow guide stabilizes the float throughout the range for consistent readings. The flowmeter is made of injection molded polycarbonate around a precision tapered pin to maintain calibration, resist breakage, and provide a clear view of the scale. The body is mounted to a stainless steel back bone with welded pipe thread inserts to absorb piping torque during installation. The scale is epoxy-coated brushed aluminum with black graduations marked along both sides of the flow tube for distinct readings. Models are available for measuring air flow in scfm or scfh. Some models come with a brass or stainless steel metering valve for precise adjustment of air flow. Hardware is included for panel or surface mounting. This flowmeter is commonly used for measuring air flow in medical equipment, air samplers, gas analyzers, pollution monitors, chemical injectors, and cabinet purging equipment, among other devices.SpecificationsScale length10"Accuracy+ or – 2% of full scaleConnections1/2" female NPT inlet and outletPressure rating100 psi/6.9 barTemperature rating54 degrees C/130 degrees FWetted materialsBody: polycarbonate; O-ring: Buna-N and neoprene; metal parts: stainless steel or brass (for models with brass valve); float (varies by range): black glass, nickel/copper alloy, stainless steel, or tungsten carbideDimensions (H x W x D)39.05 x 5.72 x 6.35 mm/15-3/8 x 2-1/4 x 2-1/2 inchesWeight1,105.6 g/39 oz.H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

The Testo 410-2 vane anemometer measures air velocity in m/s, fpm, knots, mph, km/h, and Beaufort scale, air temperature in degrees C and F, and humidity in %RH; calculates windchill, dewpoint, and wet bulb temperatures; and has hold, maximum, minimum, and timed mean calculation functions for analyzing air flow. Hold function freezes a reading on the display to aid documentation, maximum and minimum functions display highest and lowest readings since the meter was powered on or reset, and timed mean calculation function displays an average reading over time. The meter includes a calibration certificate. The LCD shows air velocity and temperature measurement simultaneously and a backlight provides visibility in low light. The unit has an auto-off mode that shuts it down after 10 minutes of non-use to conserve battery life and has a low-battery indicator. A wrist strap provides a secure hold during one-hand operation. This anemometer is used for weather monitoring and for checking air flow and temperature in ductwork, spray booths, and exhaust hoods, among other applications.

The TPI 615 single-input digital manometer has a + or - 80 inH2O (inches of water) measuring range and a + or - 0.5% full scale accuracy for measuring pressure and vacuum of dry, non-corrosive air and gas. The instrument displays measurements in inH2O, kPs, PSI, inHg, mmHg, mmH2O, and mbar. The LCD displays measurements in inches of water, and has a backlight LCD for reading in a variety of lighting conditions. The one-touch zero feature provides field calibration. The autoranging feature provides high resolution and accuracy at low pressures, and the trim mode smoothing function averages the previous four measurements to stabilize erratic readings. The manometer records Min/Max to perform pressure circuit leak testing. The display hold feature freezes the display for reading when the display is not visible during testing. The manometer automatically shuts off after 20 minutes to extend battery life. A built-in hanging hook and back-mounted magnet provides hands-free use.

They are used in laboratory, medical equipment, engineering, automotive, and heating, ventilation, and air-conditioning applications. Manometers measure any combination of gauge, absolute, or differential pressures. Gauge pressure is the amount of pressure in a system relative to the ambient pressure, absolute pressure is the amount of pressure in a system relative to an absolute vacuum, and differential pressure is the difference between two pressures. Analog manometers are composed of columns of liquid, and they use gravity and the liquid's density to calculate pressure. Becau...
