1. Product Overview
Type:
Monochrome paperless recorder: It adopts a black and white/blue background liquid crystal screen (LCD), with low power consumption, suitable for basic data recording.
Color screen paperless recorder: TFT true-color LCD screen (usually 5.6 inches to 7 inches), supporting multi-color curve display, making human-machine interaction more intuitive.
Core function: Real-time monitoring and recording of analog/digital signals such as temperature, pressure and flow rate, replacing traditional paper recorders.
2. Technical parameter comparison

3. Core functional features
General function
Paperless recording: Data is stored in CSV/PDF format and supports export to a USB flash drive.
Alarm function: Multi-channel relay output, threshold trigger sound and light alarm (color screen supports pop-up window prompt).
Trend analysis: Scroll display historical/real-time curves (color screen supports multi-curve superimposition and comparison).
Unique functions of the color screen
Visual operation
Dual operation by touch and keys, supporting switching between Chinese and English interfaces.
Dynamic flowchart display (such as industrial process simulation).
Advanced Analysis
Data is displayed in split screens (real-time values, curves, and statistical reports can be viewed simultaneously).
Peak capture, FFT spectrum analysis (applicable to vibration monitoring).
Remote management
Real-time monitoring can be achieved through the Web end or an APP (such as iOS/Android), and cloud backup is supported.
4. Application Scenarios
The application scenarios of industry monochrome recorders and color screen recorders
Temperature monitoring of industrial automation production lines (low-cost demand) Multi-parameter collaborative analysis of complex equipment (such as PLC systems)
Pharmaceutical cold chain drug warehouse temperature and Humidity recording GMP-certified laboratory (with Audit trail function required)
Energy and environmental protection: Voltage monitoring of photovoltaic power stations, comprehensive analysis of vibration and power of wind turbine generators
The temperature of food processing ovens is recorded at regular intervals, and the entire production process is visualized and traceable in compliance with HACCP
Scientific research experiments, basic physical and chemical experiments, data acquisition, high-speed dynamic signal capture (such as explosion tests)
5. Selection suggestions
Choose the single-color version: for limited budgets, single-parameter recording, and unattended environments (such as substations).
Choose the color screen model:
It is necessary to quickly locate the anomaly (distinguish the alarm status by color).
Multi-dimensional data analysis (such as simultaneously displaying temperature gradients and pressure changes).
Comply with the requirements of electronic record regulations such as FDA 21 CFR Part 11.
6. Additional services
Customized development: Supports OEM interface logos and special communication protocols (such as Profinet).
Certification standards: CE, UL, GB/T 34036-2017 (National Standard for paperless recorders).
