测试磁性金属上非磁性材料，如油漆、电镀等等。


精度为读数±10% 和2.5 microns（±10% ａnd 0.1 mil）
 

公英制：microns （metric） ａnd mils （inch）

量程为: 5-500 微米/0.25 to 20 mils （inch）

（A型） ：常温表面测量

 （B型） 用于极端温度表面测量（ -100°C到230°C/-150°F －450°F）
 

 （C型） Some objects become excessively magnetic.  For example 300 series stainless steel is non-magnetic but becomes magnetic over time.  Certain welding seams become magnetic compared to the surrounding metal.  PosiPen C allows you to compare ferrite content to a known value.

• PosiPen A for measurements on surfaces with normal temperatures
  
• PosiPen  B for measurements on surfaces with extreme temperatures （between  -150°F ａnd +450°F or -100°C ａnd +230°C）
  

  PosiPen A and B have two scales, microns （metric） ａnd mils （inch）

  Range:  0.25 to 20 mils （inch） Tolerance ±10% ａnd 0.1 mil Range: 5 to 500 microns （metric） Tolerance ±10% ａnd 2.5 microns

• PosiPen C  ferrite comparator

PosiPen C has two scales:

Ferrite content measuring range: 0-10 linear units to compare Ferrite content to an known value

Coating thickness measuring range:  0.25 to 20 mils （inch scale）  Tolerance: +10% ａnd +0.1 mil
