FEATURES
Hybrid power, power supply from green power ( handy generator ) or battery. If power source come from " Green power ", battery is no need. Wind-up the generator 20 seconds will offer several minutes energy typically.
4 in 1 professional measuring instrument: Anemometer, Hygrometer, Thermometer, and Light meter.
Anemometer use low-friction ball bearing mounted wheel design provides high accuracy at high and low air velocity.
Anemometer use the separate probe, convenient for measurement.
Light meter use exclusive photo diode and color correction filter light sensor, spectrum meets C.I.E. photopic.
High precision humidity sensor with fast response time.
Standard type K (NiCr-NiAl) thermocouple input jack suitable for all kinds of type K probe.
Concise and compact buttons arrangement, easy operation.
Memorize the maximum and minimum value with recall.
℃/℉ detection by pressing button on the front panel.
Lux/Feet-candle selection by pressing button on the front panel.
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.
Hold function to freeze the current reading value.
Microprocessor circuit assures high accuracy and reliable performance.
Large LCD, dual function display.
Auto power shut off to battery life or manual power off.
Using the durable, long-lasting components and a strong lightweight ABS-plastic housing case.
