Accurate but pricey

Precision is good though price is a bit high compared to consumer grade sensors. You get what you pay for in industrial quality.

Good display visibility

LCD is clear even in dim light. Would prefer a backlight option but overall functionality meets our needs.

Easy DIN-rail install

Snapped right onto the rail in our control cabinet. Wiring the 4-20mA output was straightforward using the manual.
