Measurement Accuracy |
Fluke 61 |
-18 °C (0 °F) to -1 °C (30 °F) ± 3 °C (5 °F)
above -1 °C (30 °F) to 275 °C (525 °F) ± 2% of reading or 2 °C (3.5 °F)
(With the instrument stable between 23-25 °C) |
Fluke 65 |
Above 0 ºC (32 ºF) : ± 2 ºC (± 4 ºF)
Below 0 ºC (32 ºF) : ± 5 ºC (± 9 ºF)
(With instrument stable at 23ºC ± 3 ºC) |
uke 63, 66, 68 |
-32 to -26 ºC (-25 to -15 ºF): ±3 ºC (±5 ºF)
-26 to -18 ºC (-15 to 0 ºF): ±2.5 ºC (±4 ºF)
-18 to 23 ºC (-0 to 73 ºF): ±2 ºC (±3 ºF)
For targets above 23 ºC (73 ºF): ±1% of reading or ±1 ºC (±2 ºF), whichever is greater |
