量程在– 200 °C 到670 °C 之間且性能穩定的溫度計

• 5608：– 200 °C 到500 °C（浸沒深度最少為80 mm）
• 5609：– 200 °C 到670 °C（浸沒深度最少為100 mm）
• 不包含校準，可選的、經NVLAP 認可的校準，實驗室編碼200348-0
• 90 ° 彎曲的干井參考儀

如果您想要一款量程在– 200 °C 到670 °C 之前且穩定的溫度計，而且十分注重校準，那麼我們的5609經濟型二等標準鉑電阻溫度計就是您的選擇。該溫度計在水三相點處的短期穩定性僅有± 7 mK，而且1/4 英寸(6.23 mm) 的直徑有助於您在浸沒深度僅有100 mm 時得到準確的測量結果。

5608 探頭在水三相點處的短期穩定性也是± 7 mK，但其直徑為1/8 英寸(3.18 mm)，使您能夠在浸沒深度僅有80 mm 時在– 200 °C 到500 °C的範圍內得到準確的測量結果。這兩種探頭均包含多種外殼長度選項，使您可以選擇恰好適合您的具體應用的尺寸。

Very stable thermometer from –200 °C to 670 °C

• 5608: –200 °C to 500 °C (80 mm minimum immersion)
• 5609: –200 °C to 670 °C (100 mm minimum immersion)
• Calibration not included, NVLAP-accredited calibration optional, lab code 200348-0
• Dry-well reference with 90 ° bend

If you want a very stable thermometer from –200 °C to 670 °C and are particular about the calibration, then look no further than our 5609 Secondary Reference PRT. Its short-term stability at the triple point of water is only ± 7 mK and its one-quarter inch (6.23mm) diameter lets you get accurate measurements in only 100 mm of immersion.

The 5608 is also a ± 7 mK probe at the triple point of water, but its one-eighth inch (3.18 mm) diameter gets you accurate measurements from –200 °C to 500 °C with only 80mm (3.1 in) of immersion. With multiple sheath length options on both of these probes, you can find the dimensions that are just right for your specific application.
