* 5 in 1 professional measuring instrument: Anemometer, Hygrometer, Type K Thermometer, Light meter. Sound level meter.
* Anemometer use low-friction ball bearing mounted wheel design provides high accuracy.
* Light meter use exclusive photo diode and color correction filter light sensor, spectrum meets C.I.E. photopic.
* Type K thermometer use standard type K (NiCr-NiAl) thermocouple input jack suitable for all kinds of type K probe.
* Humidity meter use high precision humidity sensor with fast response time.
* Sound level meter’s characteristic is simulated as
” Human Ear Listing” response, used the ” A ” frequency weighting and ” Fast ” time weighting to meet IEC 61672 class 2.
* Sound level meter can cooperate the external 94 dB sound calibrator and just press the front buttons to make the calibration
* Built- in microprocessor circuit assures excellent performance and accuracy.
* Concise and compact buttons arrangement, easy operation.
* Memorize the maximum and minimum value with recall.
* Hold function to freeze the current reading value.
* / detection by pressing button on the front panel.
* Lux/Feet-candle selection by pressing front button.
* Air velocity measuring units selection by pressing button on the front panel for five kinds of units.
* Multi channel display for relative humidity and temperature measured values or air velocity and temperature measured values at the same time.
* Zero button design makes light meter calibration.
* Rough housing case suitable for handling with one hand,
* RS232/USB computer data bus.
