Description

LR-Cal TLDMM-2.0 description

The LR-Cal TLDMM-2.0 electronic pressure calibrator features outstanding long-term stability, a 24-bit A/D converter and modern microprocessor control. It is ideal for reference pressure measurements, as well as testing and calibration tasks.

Features

Battery operation (lithium-ion battery, incl. charger)
Pressure unit switchable bar, mbar, psi, MPa, kPa, kg/cm², mHg, mmHg, mmH2O, mH2O
MIN and MAX memory, "Peak" function (peak value recording)
Programmable digital filter
Pressure connection: 1/2" BSP male, stainless steel
Measurement and display of the medium temperature
range -10...+70°C, accuracy ±1°C, resolution 0.1°C
Large, excellent readable LCD display, incl. bargraph display, background illumination
USB interface as standard

The LR-Cal TLDMM-2.0 pressure calibrator, together with the LR-Cal LPP 10, LR-Cal LPP 40 and LR-Cal LPP 60 (pneumatic) and LR-Cal LPP 700 and LR-Cal LPP 1000 (hydraulic) calibration hand test pumps, is ideally suited for on-site use. In conjunction with the LR-Cal LSP comparative test equipment (spindle pumps), it is also very well suited for operation in the laboratory and in the workshop.

The battery-powered LR-Cal TLDMM-2.0 precision reference pressure gauge operates continuously for over 50 hours on one battery charge, not least because of its intelligent automatic switch-off function. The user can switch between several pressure units, change the display resolution as well as program a digital filter. This makes the LR-Cal TLDMM-2.0 digital fine-measurement manometer suitable for all kinds of measurement and calibration tasks.

The components used (sensors, electronics, housing) are extremely resistant and ensure operation even under greater loads (vibrations, pressure shocks). In addition to the digital display, the pressure is also shown in analog form (bargraph). This is also done when the operator is in programming/setting mode. Furthermore, the medium temperature is measured and can be shown in the display alternating with the pressure display.

A practical carrying case and a DAkkS-approved ACCREDIA calibration certificate are included as standard, as are a charger and USB cable. (Instruments with measuring range from 2,500 bar and with absolute pressure ranges are supplied with factory calibration certificate as standard, here DAkkS calibration certificate optional at extra cost).

The digital reference pressure gauge LR-Cal TLDMM-2.0 is equipped with a USB interface as standard. Furthermore, the following additional variants and functions are optionally available:

Version with data logger functionality, with integrated real-time clock
Version for panel mounting with eccentric rear pressure connection
Version for external power supply 12...24 VDC, without built-in rechargeable battery

For gentle application, we recommend the rubber protective cap available as an accessory, order-code LDM80-GK.
