Manufacturer: Sper Brand: Sper

All-in-one meter measures CO2, humidity, dew point, plus air and wet bulb temperatures.Your students can investigate air quality in the classroom, laboratory, or other indoor space with this portable meter. Backlit display indicates CO2 level, humidity, and air temperature, or choose a rotating display of dew point and wet bulb temperature instead of air temperature. Meter calculates TWA (time-weighted average) and STEL (short-term exposure limit) for CO2 measurements.Additional features include audible CO2 threshold alarms; hold, min, max, and avg functions; an RS232 computer interface; and simple user calibration. NDIR (nondispersive infrared) CO2 sensor technology ensures long-term accuracy, stability, and reliability. Meter comes in a hard carrying case with 4 AA batteries.Note:Relative humidity calibration solutions are not included and must be purchased separately.

Manufacturer: Testo AG Brand: Testo Model: 400563 4170

The Testo 417 vane anemometer measures air velocity in m/s and fpm and air temperature in degrees C and F; calculates air flow volume in m3/h and cfm; and has hold, maximum, minimum, and mean functions for analyzing air flow. Hold function freezes a reading on the display to aid documentation, and the maximum and minimum functions display highest and lowest readings since the meter was powered on or reset. Mean function displays the multi-point average of recorded readings as well as the average reading during a timed measurement. 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 down the unit after 10 minutes of non-use to conserve battery life and has a low-battery indicator. This anemometer is used for monitoring air flow and temperature in ductwork, spray booths, and exhaust hoods, among other applications.

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 ...

Manufacturer: Dwyer Instruments Brand: Dwyer Model: 641RM-12-LED

The Dwyer 641RM 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. The hot-wire probe is 12" long for reaching into ductwork and has a 6-ft. long cable that allows the transmitter body to be mounted at a convenient distance from the probe. 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). 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 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.
