• data hold to freeze the displayed value
• records min/max readings
• built-in low friction vane wheel improves accuracy of air velocity in ft/min, mph, m/s, km/h, and knots
• built-in precision thin-film capacitance humidity sensor for fast response
• built in thermistor for ambient temperature measurements
• high temperature measurements using type k thermocouple
• utilizes precision photo diode and color correction filter
• cosine and color corrected light measurements
• auto power off, low battery and overrange indication
