Ventilation Psychrometer

1. Product Introduction

The ventilation psychrometer is a portable, high-precision instrument well-suited for field surveys. The complete set consists of a pair of columnar-sensor thermometers, a support stand, a three-way connector, and a ventilation tube, accompanied by a DC regulated power supply, a dual-control switch, and cables.

The humidity measurement principle of the ventilation psychrometer is the same as that of the louvered dry-wet bulb thermometer. Its sensing components are two thermometers of identical models—one dry bulb and one wet bulb. The sensing bulb of the wet bulb is wrapped with gauze, which must be moistened during observation.
