Description
For years, you've relied on the 5612, 5613 and 5614 Secondary
Reference Probes. These field durable, lab-accurate PRT's have been
replaced by the 5615, which comes with a NVLAP accredited
calibration.The 5615-12 is a Platinum Resistance Thermometer
(PRT) with an Inconed™ 600 sheath that's
305 mm (12 in) long and 6.3 mm (0.250 in) in diameter. It is a
secondary reference temperature standard designed to bridge the gap
between the highest laboratory standards and industrial or
second-tier lab locations. It has short-term accuracy of
±0.013°C at
0.01°C resolution. |

Note¹
|
"Accuracy" is a difficult term when used to describe a
resistance thermometer. The simplest way to derive "accuracy" is to
combine the probe drift specification and calibration uncertainty
with readout accuracy at a given temperature. |
| Note² |
Three thermal cycles from min to max temp, includes hysteresis,
99.9% confidence. |
| Note³ |
After 100 hours at max temp, 99.9% confidence. |
Note4
|
Temperatures outside this range will cause irreparable damage.
For best performance, transition junction should not be too hot to
touch. |
