DTLH Oversized Intelligent Temperature and Humidity Calibration Chamber
Introduction
Enforcement of verification regulations
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.
Upgraded to Automatic Verification System
- With an intelligent image acquisition system, dew point meter and industrial control computer, it can be upgraded to an intelligent temperature and humidity meter automatic verification system to realize the automation of the verification process, the automatic preservation of records and the automatic generation of reports. The metering personnel is liberated from the reading recording of the temperature and humidity meter, which greatly improves the verification efficiency and reduces labor costs.
