Hart의 5600 시리즈 써미스터 프로브는 낮은 온도 범위에서 높은 정확도를 요구하는 교정 작업에 적합한 경제적인 제품입니다. 써미스터는 어떤 응용에 있어서는 기준급 온도 센서인 PRT 이상으로 많은 장점을 제공합니다. PRT에 비해 써미스터 프로브는 작은 형태로 되어 있어서 응답 속도가 훨씬 빠릅니다.
5600 시리즈는 0°C에서 100°C까지의 온도 범위와 ±0.01°C의 정확도를 제공합니다.

Hundreds of thousands of thermistors are sold every year, but only a few have the stability necessary for use as high-accuracy thermometry standards. If you’re looking for economical lab-grade thermistor probes for accurate work across a narrow temperature range, Hart’s Secondary Reference Series thermistor probes are the best you can buy.
A thermistor offers several advantages over a PRT as a reference thermometer in some applications. First, there’s size. A thermistor is much smaller than a PRT element, and so it can be built into a much larger variety of probe shapes and sizes. The smaller element contributes to much faster response times, too.
If your application involves frequent handling, a thermistor is less susceptible to mechanical shock than a PRT. The bottom line may be better accuracy in fieldwork.
Higher base resistance and larger resistance coefficients make it easier to achieve precision readings. Better resolution and accuracy are possible for a lower cost.
These probes come in a complete assembly ready for use, and they make an excellent match with the uncertainties of our thermometer readouts: the 1504 Tweener, the 1521 and 1522 Handheld Thermometers, the 1529 Chub-E4, the 1560 Black Stack, and the 1575A and 1590 Super-Thermometers.
These probes are accurate to ±0.015°C, and each comes with a NIST-traceable calibration and a resistance versus temperature table printed in 0.1°C increments.
The Secondary Reference Series Thermistors cover the temperature range of 0°C to 100°C. No other sensors can match the accuracy and price combination of these high-accuracy thermistor probes. Try one and you’ll agree.
