ALMEMO® Measuring Instruments
ALMEMO® precision measuring
instrument with data logger
function. Comprehensive range
of functions for all application
areas. Increased measuring accuracy, fast measuring rate.
Generously dimensioned graphics display, bright illumination. 9 measuring inputs
Runs on rechargeable batteries,
charging via the device itself
Technical data and functions
• Increased measuring accuracy and stability
• Fast measuring rate, up to 50 measuring operations per second
With SD memory card, up to 100 mops, optional for 1 channel
up to 400 mops
• 9 measuring inputs, electrically isolated
• Over 65 standard measuring ranges
• Support for ALMEMO® plugs with multi-point adjustment,
special linearization, and special measuring ranges
• Option KL for independent multi-point adjustment or special
linearization programmable in 30 points and management of
calibration data saved in the sensor connector and the measuring instrument
• Higher measuring quality thanks to electrical isolation between
measuring inputs and device power supply (device ground)
• Improved cold junction compensation with 2 sensors
• Data logger with internal EEPROM, sufficient for 100,000
measured values, configurable as linear or ring memory
• Memory connector with micro SD (accessory)
• Sleep mode for long-term recording
• Generously dimensioned graphics display, bright illumination,
large display of measured values
• Measured values can be displayed graphically in line chart or
bar chart form or numerically in various sizes.
• 3 user-defined menus can be freely configured from a range of
50 functions.
• Easy to operate by means of 4 soft-keys and cursor block,
menu-guided with wizards and context-sensitive help windows
• Additional thumb-wheel for extra cursor speed
• Choice of languages : German, English, French (other options
also available)
• 2 ALMEMO® output sockets, suitable for digital interfaces,
analog output, trigger input, alarm contacts, memory card
• Runs on rechargeable batteries (as standard), high-speed charging in the device itself using mains unit, included in delivery
