General Tools and Instruments' CIH20DL Data Logging Hot Wire Anemometer/IR Thermometer measures the speed, volume and temperature of slow-moving air
General Tools and Instruments' CIH20DL Data Logging Hot Wire Anemometer/IR Thermometer is built to measure the speed, volume and temperature of slow-moving air. It is engineered to perform duct flow testing and energy audits, convert air speed readings to airflow volume measurements in units of CFM or CMM, and determine air and surface temperatures with a data logging capacity of 20,000 data points.
The handheld device is designed to measure air movement from 2 ft/min to 7,874 ft/min (20 mm/sec to 40 m/sec). Air speed readings can be displayed in any of five different units: ft/min, m/sec, mph, km/hr and knots. The CIH20DL is made to calculate airflow volumes up to 2.5 million CFM (72,000 CMM). Air temperatures from 32° to 158° F (0° to 70° C) are measured by a thermistor at the end of a telescoping probe that extends to 6 feet (1.8 meters). Surface temperatures from -25° to 999° F (-32° to 537° C) are measured by an integral infrared thermometer with an 8:1 distance-to-spot ratio.
The CIH20DL features a backlit display with three simultaneous readouts: air speed or airflow volume; surface temperature and air temperature. The readouts default to real-time values, but users can opt to display maximum, minimum or average measurements. The unit can store and recall up to nine sets of these three readings in chronological order.
