Extech 45170 4-in-1 Environmental Meter: Digital Anemometer, Hygrometer, Light Meter, and Thermometer - Pocket Sized Air Velocity, Humidity, and Lux Tester for HVAC, Greenhouses, and Home Inspection

Product Description The Extech 45170 is the ultimate multi-tool for environmental troubleshooting, designed for professionals who need accuracy without the bulk. This high-performance 4-in-1 meter combines a digital anemometer, hygrometer, thermometer, and light meter into a single, rugged, handheld device that fits comfortably in your pocket. Whether you are an HVAC technician balancing air distribution, a home inspector checking for humidity imbalances, or a greenhouse manager optimizing plant growth conditions, the 45170 provides the data you need to make informed decisions on the spot. Equipped with a low-friction vane wheel for air velocity and a precision thin-film capacitance sensor for humidity, this meter delivers lightning-fast response times. The integrated light sensor allows for quick Lux and Foot-candle readings, making it ideal for workplace safety audits and photography setup. The user-friendly interface features a large, easy-to-read display with Data Hold and Min/Max functions to capture environmental extremes over time. Built with the durability that professionals expect, the Extech 45170 ensures that you are always prepared to diagnose air, light, and moisture conditions in any residential, commercial, or industrial setting. Amazon.com The pocket-sized, four-in-one Extech 45170 hygro-thermo-anemometer-light meter displays temperature and gives you a choice between showing relative humidity or air velocity. Temperature air or surface measurements can be made using the built-in Type K input (thermocouple probe sold separately). Additionally, the 45170 includes a light sensor, and its display reverses when in light mode. Type K temperature input (probe sold separately, view larger). The 45170 features a built in thermistor for ambient temperature measurements and a precision thin-film capacitance humidity sensor for fast response. The low friction vane wheel improves accuracy when measuring air velocity in ft/min, mph, m/s, km/h, and knots. For light measurement, the 45170 utilizes a precision photo diode and color correction filter and can provide cosine and color corrected light measurements. Other features include recording of minimum/maximum readings, a Data Hold function to freeze the displayed value, auto power off, and low battery indication. The device has a temperature range of 32 to 122 degrees F, a humidity range of 10 to 95 percent relative humidity (RH), and light measurement capabilities of up to 1860 foot candles or 20,000 lux. Additionally, it offers the following air velocity measurement ranges: MeasurementsThe 45170 measures 6.1 x 2.4 x 1.3 inches (HxWxD), weighs 5 ounces, and is powered by a single 9-volt battery. It's backed by a one-year limited warranty.What's in the Box45170 Hygro-Thermo-Anemometer-Light Meter, wrist strap, 9-volt battery, operating instructions P.when('A').execute(function(A) { A.on('a:expander:toggle_description:toggle:collapse', function(data) { window.scroll(0, data.expander.$expander[0].offsetTop-100); }); }); From the Manufacturer 4-in-1 meter measures Humidity, Temperature, Air Velocity and Light.
