Description
LR-Cal TLDMM 2.0 Description
The digital reference pressure gauge LR-Cal TLDMM 2.0 is featured with an outstanding longterm stability. It is perfect for reference pressure measurements, for testing and calibration purposes. Together with the LR-Cal portable pressure test pumps it can be used mobile, on site. For higher pressure values we recommend our LR-Cal pressure comparison pumps.
The LR-Cal TLDMM 2.0 is powered by a rechargeable Li-Ion battery and is fitted with an USB interface. The instrument measures also the temperature of the pressure medium. A transit case, an USB charger, USB cable and a traceable ACCREDIA certificate (equal to DAkkS) are included in standard delivery.
Optional versions:
- Version with data logger functionality, with integr. real time clock
- Version for panel mounting with pressure port excentric back
- Version for external power supply 12...24 VDC, without built-in battery
For protection of the device we recomment the as assessory available yellow rubber protection cap, order-code LDM80-GK.
