MT-93D Split Temperature Humidity Meter

SPLIT DESIGN WITH FLEXIBLE RETRACTABLE SPRING CORD PROBE: This split humidifier humidity meter features an integrated air temperature & humidity probe connected to the main display via flexible retractable spring cord. Hold the lightweight probe in one hand to reach narrow ducts, plant tents, reptile enclosures or humidifier outlets, while holding the main host to view real-time air temperature and RH data without awkward bending, solving the blind spot trouble of integrated all-in-one thermo hygrometers.
4-IN-1 HIGH ACCURACY AIR ENVIRONMENT DETECTOR: Professional handheld thermo hygrometer simultaneously measures ambient air temperature, relative humidity, dew point and wet bulb temperature. Humidity accuracy ±4%RH, air temperature accuracy ±1.0℃, fast 300ms data refresh for HVAC, warehouse and commercial room air environment monitoring.
FULL FUNCTION BACKLIT LCD WITH DATA HOLD SYSTEM: Built-in backlight screen for clear air temperature & humidity reading in dim storage rooms or basements. Supports data hold, MAX/MIN/AVG recording (AVG based on latest 10 readings). 15-minute auto power off can be disabled to support long-time continuous air environment detection.
LOCALIZED PRECISE HUMIDITY DETECTION: The MT-93D captures accurate humidity readings in specific localized areas. Slight reading differences from whole-room hygrometers are normal if ambient humidity is uneven. It supports free ℃/℉ temperature switching and delivers up to 60 hours of continuous operation with 3 AAA batteries.
FACTORY PRE-CALIBRATED & WIDE APPLICATION: Every humidity gauge is fully calibrated before shipment, recommended annual recalibration for stable air temperature and humidity precision. Perfect for humidifier air monitoring, greenhouses, incubators, HVAC duct air testing, libraries, communication rooms and indoor home air environment tracking. Package includes meter, user manual and matched AAA batteries.
