臺灣表面溫度計DE-306 產品說明 · 測量范圍 : -50~1300 ℃ , -58 ℉ ~2372 ℉ · 分辨率 : 0.1 ℃ , 0.1 ℉ · 準確度 : -50 ℃ ~199.9 ℃ , 0.2% 讀數 +1 ℃ ·-58 ℉ ~391.8 ℉ , 0.2% 數數 +1 ℉ · 輸入信號 : K echnical Temperature scale: ℃ or ℉ User-Selective. Resolution: 1℃ or 1℉ (or 0.1℃ or 0.1℉) User-Selective. Inputs:Two K-type Thermocouples Measurement Range:-50 ~ 1300℃(-59 ~ 2000℉) Meter Operating Range:For Using at 0 ~ 50℃ Environment (32 ~ 122℉) Accuracy:(18 ~ 28℃ ambient) ±(0.3% rdg + 1℃) –50 ~ 1000℃ ±(0.5% rdg + 1℃) 1000 ~ 1300℃ ±(0.3% rdg + 2℉) -58 ~ 2000℉ The accuracy specification does not include type K thermocouple probe accuracy. Temperature Coefficient: 0.1 times the applicable accuracy specification per ℃ from 0℃ to 18℃ to 50℃. 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 in an accurate temperature standard when making the adjustment. Although making the adjustment may increase measurement errors for using different thermocouples Maximum Input: 60V dc or 24V rms ac between the input pins or any input and ground.
