Coulomb Micro Moisture Analyzer Liquid Moisture Content Determining
Test Machine
Product Introduction
The Coulomb Micro Moisture Analyzer is mainly used for measuring
and determining the trace moisture content in liquids. The
instrument features a large LCD color display with touch screen
input, a simple interface, and Chinese character prompts for
operation content. The human-computer dialogue is flexible and
convenient. In addition to having features such as high detection
sensitivity, simple operation, fast testing speed, and good
repeatability, it also has the functions of storing experimental
results, printing, and time display.
Product Features
01. Utilizes a 64-bit embedded microprocessor as the main control
core and an intelligent operating system.
02. High detection sensitivity, fast testing speed, good
repeatability, stable and reliable.
03. Real-time electrolysis curve graph, making it easier to observe
the experimental process and status.
04. Multiple analysis methods, as well as report units such as
mg/L, micrograms, ppm, and %, to meet the needs of various
industries.
05. Resolution can reach 0.01 ug, 0.001 ppm, with higher accuracy.
06. Touch screen input method, allowing for immediate data input,
and convenient data calculation.
07. Automatic test reagent solution function, with a simple
interface.
08. Electrolytic cell waterproof and sealed design, short balancing
time, and long electrolyte usage time.
09. Large touch screen operation mode, more intuitive, flexible
human-computer dialogue, and simpler operation.
10. Experimental result storage, printing function, and time display
function.
