Overview

The wet bulb black bulb temperature index instrument WBGT index measuring instrument $r $n mainly consists of three sets of measuring heads and the instrument host, with a total of four parts. Wireless data communication is used between the host and the probe, without the need for any additional wiring connections. Eliminating the hassle of connecting wires. In the absence of obstacles, wireless data transmission distance is effective within a range of 2-40 meters.

About the probe

　　⑴ The natural wet bulb temperature measuring head is covered with a layer of gauze and placed in the tested environment, relying on natural ventilation. Therefore, the obtained reading is different from the count of the ventilated dry bulb thermometer. It has the following characteristics:

measure head form Shape: cylindrical shape

measure head outside Diameter:6±1mm

Minimum length of measuring head:30±5mm

measure quantity Fan Surrounding:5-40 ℃ Accuracy: ± 0.5 ℃

There is a water cup at the bottom of the measuring head. When using, fill the cup with water. The measuring head should be wrapped with a highly absorbent material, such as cotton gauze. The gauze should be packaged in a tubular shape, with a size that fits perfectly on the measuring head. If it is too tight or too loose, it will affect the reading of the measuring head. The gauze should be kept clean. The lower end of the gauze should hang in a water tank, and the free length of the gauze in the air should not be less than30-35mm. It should be able to prevent water temperature rise caused by radiation heat. Any other type of device can be used if the same data can be obtained after calibration.

　　⑵ Black ball temperature probe

The temperature sensitive element of the black ball temperature probe is placed at the center of the black ball, and the characteristics of the black ball are:

straight Diameter:150mm

Average radiation coefficient:0.95 (unpolished black ball);

thick Degree: The thinner the better;

measure quantity Fan Surrounding:20-120℃；

accurate indeed Degree:± 0.5 ℃ at 20-50 ℃ ± 1 ℃ at 50-120 ℃

　　⑶ Air temperature probe

Attention should be paid to preventing the sensitive components of air temperature from being affected by radiation heat during measurement.

Measuring range:10-60℃；

accurate indeed Degree:±0.5℃。

To ensure the accuracy and stability of the testing, the temperature sensitive components used in this instrument are currently excellent digital temperature sensitive components.

⑷ Humidity sensor probe:

Humidity measurement range:20%-95%（0 degree-50 Humidity measurement error within the temperature range:5%.

2. Hair measuring device

The function of the hair detector is to wirelessly send the data detected by the head detector to the host. There are three transmitters, namely the head detector, abdominal detector, and ankle detector. As shown in the figure.
