DTLH Customized Smart Temperature and Humidity Calibration Chamber
Introduction
Main features of the equipment
Advanced technical principles
- Humidity control adopts the principle of moisture occurrence by shunt method, which greatly shortens the time required for stability and improves the verification efficiency compared with the principle of humidity occurrence by the double temperature method.
- Temperature control using liquid bath constant temperature plate heating technology, liquid medium heat radiation, temperature more constant, temperature field more uniform.
- The unique air circulation design in the measuring chamber ensures no dead angle airflow and adopts frequency conversion technology to speed the fan to ensure that the internal temperature field is uniform at low speed.
Product intelligence
- Fusion of measurement technology and Internet of things technology to wifi remote control to make measurement easier
- HD touchscreen control, multi-touch, greatly improve user experience,
- One-click start, automatic control, shorten the training period for metering personnel
- Timing switch machine, remote switch machine, save time, improve verification efficiency
- The shell adopts thick plate phosphating, passivation, spray molding, anti-corrosion, rust prevention, salt spray resistance;
- SUS304 for internal bile
- High precision sensor, temperature and humidity control with imported high precision platinum resistance Rotronic humidity sensor
Upgrade to Fully Automatic and Unattended Calibration
- An upgrade with smart imaging system, dew point meters, industrial cameras, robotic imaging systems, and database management software enables fully automatic temperature and humidity calibration. This system automates data recording and report generation, reducing manual labor and increasing efficiency.
Key Features
Smart Large Touchscreen
Models feature high-definition capacitive touchscreens with clearer display and multi-touch support, and are designed for intuitive smartphone-like user experience.
Mobile App Remote Control
Users operate smartphone/tablet App to remotely set temperature and humidity, start/stop the device, and monitor real-time status and fluctuations.
Programmable Calibration
Multi-stage programming function allows users to predefine five calibration points as per metrology standards. The system executes the calibration sequentially with one-click activation, eliminating the need for manual input.
Rate of Change Indicator
Temperature and humidity variation rates are displayed with customizable measurement intervals.
Real-Time Status Monitoring
Real-time stability is calculated and displayed. The stability status, USB drive connection, and Wi-Fi connection status are displayed.
Graphical Data Visualization
The system supports real-time temperature and humidity curves display, touchscreen zoom & pan functionality, and one-click screenshot and USB export.
Data Logging & Export
Data can be automatic saved in Excel format and exported to a USB drive with one-click.
Scheduled Startup
The system supports pre-programmed startup, allowing the system to reach operational conditions before work hours for immediate use.
Multi-Point Calibration
The system enables multi-point calibration for temperature and humidity sensors, ensuring minimal deviation from reference standards through segmented correction.
Segmented PID Control
The system implements multi-segment PID regulation, ensuring fast, stable adjustments with zero overshoot. The system can increase humidity from 40% RH to 60% RH within 15 minutes.
Fan Speed Control
The main internal circulation fan features variable frequency speed regulation, allowing adjustable airflow via the touchscreen interface.
Multiple Safety Protections
Includes overheat protection, low liquid level alarm, water tank refill alerts, compressor overheat warning & startup protection.
Communication Expansion
Equipped with Ethernet, Wi-Fi, USB, and RS-232 ports, enabling PC connectivity for data acquisition and system configuration.
