Data Logging Hot Wire Anemometer
SAFETY
DATA LOGGING HOT WIRE ANEMOMETER WITH CFM/CMM
AND 8:1 OR 30:1 IR THERMOMETER – CIH20DL, CIH30DL
Ideal for low FPM applications.
DIGITAL DUAL MODE REFRIGERANT LEAK DETECTOR – RLD440
Uses UV LEDs to spot leaks of fluorescent dye injected into an A/C system.
A proprietary semiconductor sensor then gauges and displays the size of the leak.
FEATURES:
• Measures and displays air speed or airflow
volume in several Imperial or metric units
• Simultaneously measures and displays ambient
temperature from 32° to 158°F (0° to 70°C) in
°F or °C with ±2% accuracy
• Measures air speeds from 2 ft/min to 7874
ft/min (20 mm/sec to 40 m/sec) with ±3%
accuracy
• Measures airflow volumes from 0 to 2.5 million
CFM (0 to 72,000 CMM) with ±3% accuracy
• Displays maximum, minimum or maximum air
speed plus temperature
• Also has 8:1 or 30:1 infrared thermometer for
remote, non-contact measurement of surface
temperatures from -25° to 999°F
(-32° to 538°C) with ±3% accuracy
• Telescoping probe and cable extend reach of
hot wire sensor and thermistor to up to
6 ft. (1.8m)
• Jumbo backlit LCD with three readouts
• Stores/recalls up to nine sets of three readings
in nonvolatile memory
• Time-stamps and saves up to 20,000 data
points at user-selected sampling rate from
5 seconds to 1 hour
• Included USB cable and interface/data logging
software enable transfer of stored data logs
from the meter’s internal memory to a PC for
tabular or graphic display and analysis
• Data hold and auto power off functions
• CE and RoHS approved
