Digital Gauge Frequently Asked Questions

Question number FAQ-0110

The tips of the gauge sensor flat measuring probes AA-220, AA-240, and AA-250 are covered with a resin-like material; is it okay to use them as they are?

The bottom surface of the flat measuring element is polished after plating to ensure flatness.
Since there is a possibility of rust occurring if left as is, a resin-type rust preventive agent is applied.
This cannot be used as is, so please use it after peeling off the resin. (It can be easily peeled off with your fingers.)

Please perform maintenance, such as applying anti-rust oil to the measuring device after use.
