The TPI 565C1 anemometer with telescoping hot-wire probe reaches into tight spaces to measures air velocity in m/s, fpm, knots, mph, and km/h and air temperature in degrees C and F; and has record, recall, and hold functions for analyzing air flow. The meter records and recalls minimum, maximum, and average readings and its data hold function freezes a reading on the display to aid documentation. For transferring and storing data directly to a PC, the meter has an output terminal for connecting to the RS-232 serial port of a compatible PC (interface cable sold separately). The LCD shows air velocity and temperature readings simultaneously. The meter has an auto power-off mode that shuts it down after 10 minutes of non-use to conserve battery life and has a low-battery indicator. It has European Conformity (CE) marking. 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 of rotations of the cups or vane. Hot-wire anemometers calculate air velocity by measuring the change in electrical resistance as air flow cools a heated wire. Pitot tube anemometers measure air pressure within a tube and calculate air velocity based on the difference in pressure between the air inside and outside of the tube. Many anemometers have digital readouts and can display air velocity readings in different units of measure, such as meters per second (m/s), feet per minute (ft./min. or fpm), knots, miles per hour (mph), and kilometers per hour (km/h).

This might be a good device, but the one I got was corroded inside and didn't work, I returned it

Well made. Convenient to use. Good repeatability of readings. Does the job for the price.

I'm using this anemometer to measure the air velocity distribution of an automotive radiator and calculate the volumetric flow rate of the air. As a hobbyist, I wanted a device that didn't cost a fortune yet was accurate enough for me to measure air velocity at idle speed. Another important consideration for me was the size of the sensing element. This device has a sensor that does not disrupt the air flow very much and can be inserted into tight spaces. With that in mind, here are my pros and cons:Pros: (1) small size and shape of sensor, (2) reasonable price, (3) good air velocity range, (4) has a built-in thermistor for temperature readingsCons: (1) sliding protective sleeve for sensor should be a tighter fit on the wand, (2) device should have a flow straightener in order to dampen the fluctuations due to stray air currents (not an issue when used in ducts), (3) device sometimes needs to be zeroed several times until the display shows zero.

Works good. A few issues with power but it could have been the high humidity. Will follow up in a few months. Great instrument for the money

I use this anemometer to take quick greenhouse air movement readings and works well for quick measurements. A good product when considering most anemometers are very expensive. A good product.

I purchased this TPI hot-wire anemometer/air velocity meter several years ago and it seems to be holding up well. For a moderately priced unit, I think it has a lot of good features. It came with a rubber overboot and a decent nylon storage case as well as the 6 AAA batteries it uses. The unit has auto power off and reads degree C or F with temperature range from -5F to 175F as well as air velocity from 0.2 m/s to 20 m/s. It can be set to display either m/s, km/s, ft/min, knots or miles/h, but doesn't read CFM directly, so the reading must be converted using the formula in the manual. It has data recording and there is a 3.5mm serial RS232 output jack for printing and viewing the readings on a computer, but the actual RS232 cable isn't included. The remote hot-wire probe tip on this unit is approximately 3/8" in diameter and the probe is permanently attached with a cable that allows for an overall probe length of about 4-feet when fully extended, so it has plenty of reach for getting deep into plenums and ductwork. TPI recommends having the meter recalibrated once a year, so will need to be shipped to their service facility for that. Overall though, this meter seems to be well made and hasn't given me any trouble to date, so I would have no issue with recommending it.
