Amprobe THWD-10 Relative Humidity and Temperature Meter

Amprobe THWD-10 Relative Humidity and Temperature Meter: Tools & Home Improvement. Amprobe THWD-10 Relative Humidity and Temperature Meter: Tools & Home Improvement. Relative humidity (RH) and temperature meter measures temperature, relative humidity (RH), dew point, and wet bulb, and is used for HVAC, indoor air quality, and environmental applications 。 Two temperature sensors (K-type thermocouple and thermistor) for a range of dual-scale temperature readings in F and C 。 Capacitive humidity sensor ranges from 0 to 100 percent relative humidity (RH) 。 Data hold for recording data, and minimum, maximum, and average temperature readings 。 Five-digit LCD display 。 The THWD-10 relative humidity (RH) and temperature meter simultaneously measures relative humidity, dew point, and wet-and dry-bulb temperature using two temperature sensors (K-type thermocouple and thermistor) that provide a range of dual-scale temperature readings, and is used for HVAC, indoor air quality, and environmental applications. The K-type thermocouple sensor measures temperatures from-50 to 1,832 degrees F (-50 to 1,000 degrees C), and has a resolution of 0.2 degrees F (0.1 degrees C). The thermistor temperature sensor has a temperature range from 32 to 140 degrees F (0 to 60 degrees C), and has a resolution of 0.1 degrees F and C. The meter has minimum, maximum, average, and hold functions for recording data, and relative zero functionality stores reference points. It requires four AAA batteries (included), and includes, a k-type thermocouple, a white box and instructions. Specifications K-type thermocouple temperature accuracy (operating temperatures 64 to 82 degrees F) For one year (not including thermocouple error): for temperatures-50 to 1,832 degrees F, accuracy is Plus or, (0.1 percent of reading Plus 2 degrees F; for temperatures-58 to-328 degrees F, accuracy is Plus or, (0.05 percent of reading Plus 1.4 degrees F) K-type thermocouple temperature accuracy (operating temperatures 18 to 28 degrees C) For one year (not including thermocouple error): for temperatures-50 to 1000 degrees C, accuracy is Plus or, 0.1 percent of reading Plus 1 degree C Thermistor temperature accuracy (degrees F) For temperatures 32 to 50 degrees F, accuracy is Plus or, 4 degrees F, for temperatures 50 to 113 degrees F, accuracy is Plus or, 1 degree F, for temperatures 113 to 140 degrees F, accuracy is Plus or, 4 degrees F Thermistor temperature accuracy (degrees C) For temperatures 0 to 10 degrees C, accuracy is Plus or, 2 degrees C, for temperatures 10 to 45 degrees C, accuracy is Plus or, 0.5 degrees C, for temperatures 45 to 60 degrees C, accuracy is Plus or, 2 degrees C RH accuracy Plus or, 2.5 percent at 77 degrees F (25 degrees C) and 10 to 90 percent RH, and Plus or, 5 percent at 77 degrees F (25 degrees C) and 0 to 10 percent RH RH sensor response time (90 percent of total range) 60 seconds typical Sensor hysteresis (excursion of 10 percent to 90 percent to 10 percent) Plus or, 1 percent RH typical Wireless frequency 910 to 920 megahertz, low current consumption less than 1 milliamp (mA), transmitting distance up to 25 meters away without magnetic interference Operating environment at less than 80 percent relative humidity 32 to 122 degrees F (0 to 50 degrees C) Storage environment (with battery removed) at less than 70 percent relative humidity-4 to 140 degrees F (-20 to 60 degrees C) Dimensions 9.5 x 6.22 x 3 inches (241.3 x 157.98 x 76.2 mm) (H x W x D) Weight Approximately .67 lb. (304g), including batteries H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. A thermohygrometer is a combination thermometer to measure temperature, and hygrometer to measure humidity. It monitors relative humidity and temperature in lab, office, home, and greenhouse applications manufactures electrical testing equipment for commercial, industrial, and home use. The company was founded in 1948 and is headquartered in Everett, WA What’s in the Box? Meter AAA batteries (4) K-type thermocouple White box Instructions 。 。 。
