SARTORIUS LMA300PA-000U

Overview

SARTORIUS LMA300PA-000U is a modular loss-on-drying moisture analyzer (thermal gravimetric moisture meter) from the Sartorius LMA300P series. The suffix “PA” represents the control/display terminal unit and “000U” is the standard international version configuration. SARTORIUS LMA300PA-000U is the operator control head, paired with the matching heating-weighing base module to complete rapid moisture testing of solid, granular, paste and powder samples. SARTORIUS LMA300PA-000U is widely supplied as exchange spare for pharmaceutical, food, chemical and battery material QC laboratory maintenance.

Features

SARTORIUS LMA300PA-000U features a high-contrast graphic display and membrane keypad for local method setup, test monitoring, curve viewing and result review. It supports storage of multiple drying methods with programmable temperature ramp, hold time and endpoint criteria, which can be quickly recalled for different sample recipes. SARTORIUS LMA300PA-000U adopts modular bus architecture; one control head can communicate with multiple heating modules, and the terminal can be hot-swapped without stopping the connected weighing and heating unit. It records test curves, moisture results, sample IDs and operator information, supporting GLP-compliant data traceability and audit logging. SARTORIUS LMA300PA-000U supports RS232 communication to connect with printers, LIMS systems and host PCs for automatic data export. It includes built-in hardware self-diagnosis for communication loss, temperature anomaly and weighing system error, with configurable alarm prompts. The heating base uses infrared quartz heating and a high-precision internal balance to continuously track weight loss during drying.

Specs

SARTORIUS LMA300PA-000U is the control terminal only, not including the heater and weighing module. It connects to the LMA300P series internal digital bus. Communication: RS232 serial port. Method storage, trend graph display and GLP audit trail are standard functions. The matched heating module defines weighing capacity, balance resolution, temperature range and moisture measurement range. This is a legacy Sartorius moisture analyzer platform, and the MA series is the newer replacement family. SARTORIUS LMA300PA-000U is widely supplied as spare for laboratory analyser panel replacement.

Principle

SARTORIUS LMA300PA-000U sends drying recipe parameters to the heating base module and receives real-time weight, temperature and moisture readings during the test. The heating module evaporates moisture from the sample under controlled temperature, and the integrated balance continuously measures weight reduction. The control head of SARTORIUS LMA300PA-000U calculates moisture percentage based on loss-on-drying principle and draws moisture/time and temperature/time curves. When the weight change rate meets the preset stable endpoint condition, the analyzer automatically stops heating and locks the final moisture result. If communication interruption, over-temperature or weighing fault occurs, the system triggers a safe stop and saves the partial test record.

Applications

SARTORIUS LMA300PA-000U is deployed in quality control laboratories for food, feed, pharmaceutical raw materials, plastics, ceramics, battery powder and chemical intermediate materials. It is used for fast routine moisture content testing to verify raw material quality and production batch consistency. SARTORIUS LMA300PA-000U is selected for spare inventory and analyser upgrade projects for Sartorius LMA300P moisture analysis systems. It is the human-machine interface and data processing core of this modular thermogravimetric moisture analyzer.
