DT8891E專業(yè)溫度表是由深圳市華之慧實(shí)業(yè)股份有限公司生產(chǎn)的高精度溫度測量儀器。該產(chǎn)品采用K型熱電偶和紅外線溫度探測儀作為傳感器，提供0.1℃/0.1℉的高分辨率溫度測量。它具備四通道K型熱電偶測溫和紅外測溫功能，可同時測量多個點(diǎn)的溫度。

該溫度表配備了大液晶背光顯示屏，即使在光線較暗的環(huán)境中也能清晰讀取數(shù)據(jù)。它能夠顯示最大值、最小值和平均值，方便用戶進(jìn)行數(shù)據(jù)記錄和分析。此外，每個通道可以保存18,000個數(shù)據(jù)記錄，通過USB接口可將數(shù)據(jù)傳輸至電腦進(jìn)行進(jìn)一步分析。

DT8891E專業(yè)溫度表廣泛應(yīng)用于電力設(shè)施故障診斷、科研實(shí)驗(yàn)溫度監(jiān)控、企業(yè)生產(chǎn)與存儲的溫度檢測和監(jiān)控等領(lǐng)域。其自動關(guān)機(jī)功能可延長電池壽命，確保長時間使用。目前，該產(chǎn)品的價格在1480元人民幣左右。

The DT8891E professional thermometer is a high-precision temperature measuring instrument produced by Shenzhen Hua Zhi Hui Industrial Co., Ltd. This device uses K-type thermocouples and infrared temperature sensors to provide temperature measurements with a high resolution of 0.1℃/0.1℉. It features four-channel K-type thermocouple temperature measurement and infrared temperature measurement, allowing for simultaneous temperature readings at multiple points.

The thermometer is equipped with a large LCD backlight display, ensuring clear visibility of data even in low-light conditions. It can display maximum, minimum, and average values, facilitating data recording and analysis for users. Moreover, each channel can store up to 18,000 data records, and the USB interface allows for data transfer to a computer for further analysis.

The DT8891E professional thermometer is widely used in various fields, including power facility fault diagnosis, temperature monitoring in scientific research experiments, and temperature detection and monitoring in enterprise production and storage. Its auto-shutoff function helps extend battery life, ensuring long-term use. Currently, the price of this product is around 1480 RMB.
