Hygrometer, Thermometer, and Light meter.

* Tiny bone shape with 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.

* Low-friction ball bearing mounted wheel design provides

high accuracy at high and low air velocity.

* Exclusive photo diode and color correction filter light sensor,

spectrum meets C.I.E. photopic.

* High precision thin-film capacitance humidity sensor with

fast response to the humidity changes.

* 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.

* Concise and compact buttons arrangement, easy operation.
* Memorize the maximum and minimum value with recall.
* / selectable by pressing button on the front panel.℃℉
* Lux/Feet-candle selectable by pressing button on the front

panel.

* Air velocity measuring units selectable 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.
