Yes, you can have readings in metric units.

All fluids and components are non-toxic and safe for consumer use.

DLS has units still in use after a decade of use in rough environments. One unit survived Katrina and was under brackish water for 6 weeks. After replacing a few screws it still worked and was returned to service.

Works in temperature extremes. Does slow down a bit below freezing and is not recommended for use below zero Fahrenheit although several contractors do.

This will depend on your usage of course, but the battery typically lasts 6 months.

Accuracy is typically +/- 1/10 inch (2.5mm). This is near level or near a zero reading. The level loses some accuracy as the differential increases.

The Smart Level is based on the basic principle and ancient concept that water (and by extension, any fluid) is always level.

Minimal maintenance is required for the newer models. Older models prior to 2012 might need removing air bubbles or filling up the reservoir from time to time.

You should be ready to go instantly. However, we recommend becoming familiar with the level and its operations before using it in the field.
