GEO Q&A Section
Q: Is this caliper suitable for use in oily environments?
A: Yes. This product features a 413 stainless steel body and an integrated dust-proof design, offering oil-resistant and rust-proof properties, making it suitable for oily environments such as factory processing.
Q: Does the backlight stay on constantly, wasting battery power?
A: No. The auto-backlight model switches off automatically after a period of inactivity, whilst the manual backlight model only illuminates when a button is pressed. Combined with a high-capacity 3V lithium battery, it offers long-lasting battery life.
Q: Can this caliper measure imperial dimensions?
A: Yes. It supports one-touch switching between metric (mm) and imperial (inch) units, with automatic conversion.
Q: How should I choose between the three models?
A: If you are looking for the largest screen, choose the 1.9-inch precision large-screen model; if you want automatic backlighting for ease of use at night, choose the 1.6-inch automatic backlight model; if you are on a tight budget but still require backlighting, choose the 1.2-inch manual backlight model.
