憑藉全面的ITS-90 校準展現二級水平性能

• 外殼直徑較小，3.2mm（0.125 英寸）
• 穩定性優良
• 納入了ITS-90 係數>
• 經NVLAP 認可，校準溫度範圍在– 200 °C 到500 °C 之間，實驗室編碼200706-0

由於憑藉全面的ITS-90 校準展現了二級水平性能，Hart 的5618B 系列PRT 成為臨界溫度測量的絕佳選擇。這些行業標準探頭配有直徑為3.2 mm（1/8 英寸）的外殼，縮短了響應時間，卻不會降低精密度。這種小直徑的5618A 探頭在許多浸沒深度受限的應用場合中均能實現良好的操作。在浸沒深度較淺的應用場合中，較大直徑的探頭則會帶來更多測量誤差，因為這類探頭會在環境與傳感器之間傳導更多熱量。

Secondary level performance with full ITS-90 calibration

• Small diameter sheath, 3.2mm (0.125 in)
• Excellent stability
• Includes ITS-90 coefficients
• NVLAP-accredited calibrated from –200°C to 500°C, lab code 200706-0

For secondary level performance with full ITS-90 calibration, Fluke Calibration’s 5618B series PRTs are an excellent choice for critical temperature measurements. Featuring a 3.2 mm diameter (1/8 in) sheath, these industrial standards probes have reduced response time without compromising precision. This small diameter 5618A probe works well in many applications where immersion depth is limited. Larger diameter probes give more measurement error in short immersion depth applications because they conduct more heat between ambient and the sensor.
