Product catalog summary

Calibration and Standards
The document specifies that the DAkkS accredited calibration or works calibration KE90xx for measuring instruments complies with DIN EN ISO/IEC 17025 standards, ensuring the reliability of test resources.

Technical Specifications
The measuring instrument features one ALMEMO® socket with a precision class of C. It operates at a measuring rate of 2.5 mops and supports various measuring ranges including temperature, voltage, current, and humidity. Specific ranges include:

Temperature: -200 to +950 °C for thermocouples and -20 to +100 °C for NTC sensors.
Voltage: -26 to +26 mV, -260 to +260 mV, 0 to 2.6 V.
Current: 0 to 26 mA, 4 to 20 mA.
Humidity: 0 to 100% RH.

The instrument does not support double connectors with differential voltage/current inputs.

Display and Controls
The device includes a 7-segment LCD display for measured values and functions, with a keypad consisting of 7 silicone keys for operation.

Power Supply
It is powered by a set of 3 AA alkaline batteries with a current consumption of approximately 10 mA without input modules. The sensor power supply is 9 V with a maximum of 0.5 A.

Design and Environmental Conditions
The housing is made of ABS material, suitable for temperatures up to 70 °C, with dimensions of 127 x 83 x 42 mm. The instrument is designed for compact use with over 35 measuring ranges and can operate in battery mode.

Additional Features
The instrument supports ALMEMO® plugs with multi-point adjustment and includes functions such as zero-setting, saving of maximum/minimum values, and a hold function. Test functions include segment monitoring, range monitoring, sensor breakage indication, and battery voltage check.

Accessories and Options
Accessories available include rubberized impact protection, DIN rail mounting, magnetic fastening, and an instrument case. The standard delivery includes batteries, operating instructions, and a manufacturer’s test certificate.

Model and Ordering Information
The compact measuring instrument model is ALMEMO® 2450-1L, with the order number MA24501L.
