1. FEATURES

* 5 in 1 professional measuring instrument: Anemometer,

Air flow, Hygrometer, Thermometer, and Light meter.

* Multi channel display for relative humidity, temperature,

and air velocity measured values at the same time.

* Air velocity measuring units selectable by pressing button on

the front panel for five kinds of units.

* Air flow (CFM. CMM) measurement by setting the desired area

dimension.

* Low-friction ball bearing mounted wheel design provides

high accuracy at high and low air velocity.

* High precision thin-film capacitance humidity sensor with

fast response to the humidity changes.

* °F/°C selectable by pressing button on the front panel.

Lux/Feet-candle selectable by pressing button on the front panel.

* Standard type K (NiCr-NiAl) thermocouple input jack

suitable for all kinds of type K probe.

* Built-in microprocessor circuit assures excellent

performance and accuracy.

* Button arrangement allows easy operation.

Maximum and minimum value with recall.

* Hold function to freeze the current reading value.

* Lightweight and small size case design

are suitable for handling with one hand.

* Wristlet design provides extra protection to the instrument

especially for user one hand operation.
