Features include large, bold numbers, a dual display for temperature and humidity, max/min temperature and humidity memory, and a freeze alert. Mounts easily by key hole, Velcro®, magnet or the flip-out desk stand.
Extech EasyView Light Meter
This compact meter features a large, easy-to-read display with bar graph. Measures foot candles up to 40,000 in four ranges and up to 400,000 lux in five ranges. The meter utilizes a precision silicon photodiode sensor and features a 5’ coiled cable for easy storage. Other features include min/max function, cosine and color corrected measurements, peak hold, data hold, auto power-off, and indicators for low battery and overrange. Built-in stand, remote sensor with protective cover, protective holster, and 6 AAA batteries included.
Kestrel 3500 Pocket Weather Meter
Providing a wealth of weather information, the Kestrel 3500 measures barometric pressure, altitude, temperature, humidity, wind speed, wind chill, dew point, wet bulb, and heat index. Measure current, maximum, and average wind speed in meters per second, kilometers per hour, miles per hour, feet per minute, knots, or Beaufort Force. Temperature, wind chill, heat stress, and dew point are shown in °C or °F. Relative humidity is displayed as a percentage. Pressure is measured in hPa or inHg. Altitude is displayed in feet or meters. Measurements are shown on a large backlit display. An innovative thermally-adjusted humidity sensor provides stable, accurate measurements even during abrupt condition changes. Other features include a real-time clock, hold function, quick response external thermistor, a high precision pressure sensor, and a user-replaceable impeller. Housed in a waterproof body that floats, the meter features a protective cover with sure-grip overmolding. Lanyard and battery included.
The Kestrel 5500 does it all – measures altitude, barometric pressure, crosswind, density altitude, dew point temperature, direction (wind direction and orientation), headwind/tailwind, heat stress index, relative humidity, station pressure (absolute pressure), temperature, wet bulb temperature (Psychrometric), wind chill, and wind speed. The Kestrel 5500 features a large, high contrast screen, dual color backlight, scratch- and breakage-resistant window, corrosion-resistant battery compartment with secure door, intuitive user-interface, plus it tracks and logs over 10,000 sets of time-stamped data. Data can be transferred to a PC/MAC with the optional waterproof USB Data Transfer Cable (sold separately). Combine the Kestrel 5500 with a portable vane mount and portable tripod (each sold separately) for a data-logging weather station that rotates in even the slightest breeze and is ideal for short-term monitoring. This versatile, waterproof instrument floats, features an easy-to-read backlit display, and has an auto shutdown feature which activates after 15 minutes without a button press (feature can be disabled). Lanyard, protective pouch, lithium AA battery (average life 400 hours), certificate of conformity, and instruction manual are included.
SkyScan Lightning/Storm Detector Model SS-P5
Detect lightning as far as 40 miles away! Thanks to the patented dual antenna technology and digital microprocessor, the SkyScan is the most reliable and accurate lightning detection system available. With the push of a button, SkyScan detects lightning and accurately tracks its approach with both an audible tone and four LEDs which are ranged in miles to let you know if the storm is moving towards, away or parallel to your position. In case of a severe storm, the SkyScan warns of strong thunderstorms or squall lines by sounding a continuous alarm for 15 seconds and illuminating the Severe Storm LED for a minimum of 15 minutes and repeats this every 15 minutes until the severe weather activity has cleared. Other features include a rugged weather-resistant case, a range select that allows audible warnings to be set at desired range, and a battery save function. Operates on six AA batteries.
