Manufacturer: Thomas Scientific Brand: Thomas Model: 4091

The Thomas Traceable Digital Anemometer with vane probe measures air velocity in m/s, fpm, knots, and km/h, and air temperature in degrees C and F; and has a hold switch that freezes a reading on the display to aid documentation. The vane probe has a 4-ft. cable for reaching into ductwork. A bench stand is built into the back of the meter for viewing readings on the 3-1/2 digit LCD. The meter includes a calibration certificate from an International Organization for Standardization (ISO) 17025 laboratory accredited by the American Association for Laboratory Accreditation (A2LA) with traceability to National Institute of Standards and Technology (NIST) standards. This anemometer is used for monitoring air flow and temperature in ductwork, spray booths, and exhaust hoods, among other applications. SpecificationsAir velocity range0.4 to 30.0 m/s; 80 to 5,910 fpm; 0.8 to 53.3 knots; 1.4 to 108.0 km/hAir velocity resolution0.1 m/s; 10 fpm; 0.1 knots; 0.1 km/hAir velocity accuracy+ or - (2% + 1 digit)Air temperature range0.0 to 60.0 degrees C/32.0 to 140.0 degrees FOperating environment0 to 50 degrees C/32 to 122 degrees F at less than 80% relative humidityPower(1) 9V battery (included)Vane diameter2-3/4"Main unit dimensions (H x W x D)6-1/4 x 3 x 1-1/4 inchesWeight1 lb.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. Anemometers, also called wind meters, measure air velocity and are most commonly used for weather monitoring to determine wind speed and for HVAC applications to determine air flow within ducts. In addition to air velocity, anemometers may measure wind direction, air pressure, air flow volume, air temperature, humidity, light, and other properties. The most common types of anemometer are cup, vane, hot-wire, and Pitot tube. Cup and vane anemometers calculate air velocity based on the number of rotations of the cups or vane. Hot-wire anemometers calculate air velocity by measur...

Dwyer® Series CDTR Carbon Dioxide, Relative Humidity and Temperature Transmitters reduce the number of sensors mounted on a wall or in a duct. By combining CO2, RH, and temperature in one device, system integrators are able to lower installation time of mounting multiple housings, while lowering material cost at the same time. Even with the three sensors combined into a single unit, replacement cost is not increased due to the pluggable nature of the humidity sensor, which allows it or the temperature to be replaced at a fraction of the cost of a new CO2 transmitter. Like our popular Series CDT Carbon Dioxide Transmitter, a single-beam dual-wavelength non-dispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied* and unoccupied buildings against light source aging effects. The single-beam dual-wavelength sensor technology provides the highest level of accuracy compared to Automatic Baseline Correction methods which can unintentionally shift the calibration based on CO2 levels and barometric pressure conditions. In order to achieve a higher level of accuracy, the Series CDTR also includes digital barometric pressure adjustment and the ability to field-calibrate the sensor. Universal outputs for both carbon dioxide and relative humidity allow users to select the transmitter output to be 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC to work with virtually any building management controller. Additionally, passive thermistor or RTD sensor can be ordered for a temperature output. Push buttons are standard on all configurations of the transmitters for access to the menu structure, but wall mount configurations can be ordered without the buttons.

Manufacturer: Dwyer Instruments Brand: Dwyer Model: 641-24-LED

The Dwyer series 641 air velocity transmitter combines a hot-wire anemometer that has 16 user-selectable ranges for measuring air velocity in m/s or fpm with a transmitter that provides an isolated 4 to 20 mA output signal proportional to the measured velocity. Designed as a three- or four-wire device, the transmitter has screw terminals for connecting to either an AC or DC power source and to a power or loop receiver (sold separately). Its 1/2" male NPT process connection allows direct mounting to pipe fittings or a pipe flange, and it may also be mounted using a 5/16" compression fitting. An adjustable output filter stabilizes readings when measuring turbulent flow. The unit is for use with clean, dry air and compatible, non-combustible gases. It has European Conformity (CE) marking. Models are available with various probe lengths, without or with an LED display for observing readings at the point of measurement. The 4-1/2 digit red LED has resolution of 0.01 m/s, 1 fpm (10 fpm at 10,000 and 15,000 fpm ranges). This anemometer is used for monitoring and measuring air flow in HVAC (heating, ventilation, and air conditioning) systems, exhaust stacks and hoods, and clean rooms, among other applications. SpecificationsSelectable air velocity ranges1.25, 2.5, 5, 10, 15, 25, 50, and 75 m/s; 250, 500, 1,000, 2,000, 3,000, 5,000, 10,000, and 15,000 fpmAir velocity accuracy3% of full scale with process air at 0 to 50 degrees C/32 to 122 degrees F; 4% of full scale with process air at -40 to 0 degrees C/-40 to +32 degrees F and 50 to 100 degrees C/122 to 212 degrees FProcess connection1/2" male NPTPower12 to 35VDC or 10 to 16VAC, 1.5 ampOutput signal4 to 20 mA, isolated 24V source, 3- or 4-wire connectionMaximum loop resistance600ΩPressure rating100 psi/6.89 barTemperature ratingProcess air: -40 to +100 degrees C/-40 to +212 degrees F; ambient air: 0 to 60 degrees C/32 to 140 degrees FTransmitter length113.11 mm/4-29/64"WeightWithout LED: 357.2 g/12.6 oz.; with LED: 377 g/13.3 oz.
