229 mm (9 in) Small Diameter Probe, "D" (5-pin DIN for Tweener Thermometers)
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.
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
