Product Features:
This enthalpy difference laboratory testing system offers advantages that traditional test benches lack, such as high precision, accurate data, fast testing speed, convenient operation, energy efficiency, and low investment. It has become an indispensable testing equipment for comprehensive air conditioning manufacturers and testing institutions, receiving high praise from users.
All equipment in this testing system operates using a programmable logic controller (PLC) + human-machine interface (HMI) control, featuring an intuitive interface, convenient and reliable operation. Measured values are processed and archived by computer data acquisition, automatically generating test reports. Additionally, this enthalpy difference laboratory can analyze test results and testing data.
The deviation in comparison results with the laboratory does not exceed 3%. It meets the technical requirements for national laboratory accreditation or production license applications. Provides procedural documents and technical support services for laboratory accreditation, production license applications, etc.
