- The LR-Cal DFP is a microprocessor based digital pressure gauge, made of particulary high long-term stable analogue section and a 16 bit A/D converter which ensure 65,000 internal divisions. These features, together with a 0.1% accuracy class, make it ideal as a reference instrument: in fact, the LR-Cal DFP is proposed as a first line sample for Quality Insurance Laboratories.
- The digital reference pressure gauge LR-Cal DFP has internal batteries with 1 year autonomy, also guaranteed by the Auto-PowerOff function, which activates if no measurement changes are detected in the previous 30 minutes (adjustable).
- Accuracy ±0.1% FS
- Pressure ranges up to 2000 bar
- 1 year autonomy without recharging (battery operated)
- Pressure unit "bar", conversion to Force (daN, KN) or Weight (to, kg)
- PEAK function (positive and negative)
- Digital filter (adjustable)
- Pressure connection: 1/2" BSP male
- Clear and easy to read LCD with large figures and bargraph
