5611A Series – Silicone-coated secondary thermistor probes: With a diameter at the tip of just 1.5 mm ( 1/16”), the 5611A''s tip has the smallest diameter of any of our secondary reference thermistors and can fit nearly anywhere. Its faster response time, flexible sheath, and silicone coating make the 5611A great for use in many applications. However, applications involving silicone oil could damage the thermistor and should be avoided.

Available for sale in the United States and Canada only.
