• Accurate and highly environmentally resistant, assisting with many types of measurements.
• Ratchet thimble provides better operability for one-handed operation.
• Oil-resistant material used for all plastic parts.
• Models equipped with a Digimatic output port can form part of a statistical process control or networked measurement system.
