- The LR-Cal TLDMM is a microprocessor based digital pressure gauge, made of particularly high long-term stable analogue section and a 16 bit A/D converter which ensure 65,000 internal divisions. These features, together with a 0.05% accuracy class, make it ideal as a laboratory instrument: in fact, the LR-Cal TLDMM is proposed as a first line sample for Calibration Laboratories and is provided with an ACCREDIA certificate of calibration, traceable to international standard.
- The pressure calibrator LR-Cal TLDMM has internal batteries with 1 year autonomy, also guaranteed by the Auto-Power-Off function, which activates if no measurement changes are detected in teh previous 30 minutes.
- Accuracy ±0.05% FS (incl. ACCREDIA certificate of calibration)
- Pressure ranges up to 2000 bar
- Battery operated (life time >1 year)
- Selectable pressure units bar, mbar, psi, MPa, kPa
- MIN- and MAX memory, PEAK value function
- Adjustable digital filter
- Pressure port 1/2" BSP male in stainless steel
- Large LCD screen including bargraph display
