台湾表面温度计DE-305
台湾表面温度计DE-305产品说明
温度范围:摄氏或华氏,用户选择。 分辨率:摄氏1oC或华氏1oF(或0.1oC或0.1oF) 用户可选择 输入:一个K型热电偶 测量范围:-50~1300oC,(-59~2000oF) 仪器操作范围:使用在0~50℃ 环境(32~122oF) 精度:(18~28oC环境) ±(0.3%读值+摄氏1o)-50~1000oC ±(0.5%读值+摄氏1o)1000~1300oC ±(0.3%读值+ 2oF)-58~2000oC 其精确度规范不包括 D型热电偶探头的精度。 温度系数: 0.1倍于每个应用精度范围 从摄氏0度至摄氏18度,至摄氏50℃ 误差。偏差。 误差是由于某个热电偶引起,这实际上可消除,(或者)超过了量程,(或者)使用一 个槽形面板(可能是变了形的,引起误差)。 偏差:是当在仪表上调整和温度精度标准调整时(所产生)。当使用不同的热电偶,虽然作了调整,(还是可能会产生偏差)。 *大输入:60V的直流或交流有效值24V,在输入引线或任何输入和接地之间(的电压)。
Technical Temperature scale: oC or oF User-Selective. Resolution: 1oC or 1oF (or 0.1oC or 0.1oF) User-Selectable Inputs: One K-type Thermocouple Measurement Range: -50 ~ 1300oC, (-59 ~ 2000oF) Meter Operating Range:For Using at 0oC ~ 50oC Environment(32 ~ 122oF) Accuracy:(18~28oC ambient) ±(0.3%rdg + 1oC)-50 ~ 1000oC ±(0.5%rdg + 1oC)1000 ~ 1300oC ±(0.3%rdg + 2oF)-58 ~ 2000oC The accuracy specification does not include type D thermocouple probe accuracy. Temperature Coefficient: 0.1 times the applicable accuracy specification per oC from 0oC to 18oC to 50oC Error Offset:Errors contributed by one particular thermocouple may be practically eliminated, over a limited measurement range, using a recessed front panel OFFSET adjust on the meter and an accurate temperature standard when making the adjustment. Although making the adjustment may increase measurement errors for using different themocouples Maximum Input: 60V dc or 24V rms ac between the input pins or any input and ground. 台湾表面温度计DE-305 General Display: 31/2 digit liquid crystal display (LCD) with maximum reading of 1999. Sampling Rate: 2.5 times per second Battery: One 9 V battery (6F 22) Dimensions (mm): 148(H)x71(W)x36(D) Weight: 208g (including battery) Power current:Approx. DC 2.8mA (typical) Enclosure 1. Manual 2. Battery 9V . 3. Rubber Holster
