Full-link Quality Control
Tkind builds a full-link quality control system covering R&D, incoming material inspection, production and finished product testing. All energy metering hardware passes dozens of reliability tests on temperature resistance, waterproofing and durability. Key procedures adopt 100% on-line full inspection, and the MES system records traceable production data for every device. Following ISO standards strictly, we eliminate risks like metering errors and circuit faults at the source. It ensures long-term stable operation of heat meters and energy managers, delivering high-precision energy-saving equipment via standardized QC procedures.
Strict Reliability Testing
Tkind operates an in-house professional reliability laboratory. For our full range of core metering devices including ultrasonic heat meters, electromagnetic heat meters, IoT thermostats and energy consumption collectors, we conduct simulated tests under extreme conditions such as high-low temperature cycling, aging durability, thermal shock, electromagnetic interference, water and dust resistance. Every product undergoes multiple precision calibrations and error reviews before delivery, ensuring accuracy indicators remain within the industry’s optimal range.
Standardized testing workflows eliminate design and production defects in advance, greatly reducing on-site maintenance failures and rework rates. We deliver long-term stable, highly accurate and reliable energy metering devices and supporting systems for diverse scenarios including hospitals, geothermal projects and commercial properties.
Relevant Certifications
Full-process Quality Control
Tkind builds a full-process QC system covering incoming inspection, processing, assembly, calibration, aging and delivery for heat meters, energy collectors and AC thermostats. Every workshop procedure implements triple inspection: self-check, mutual check and professional check. The MES system records production data in real time to trace component batches and device serial numbers. Complying with national metering standards and ISO9001, we eliminate metering errors and circuit defects in advance, stabilize product precision in mass production and cut on-site rework rates, delivering durable energy-saving metering hardware for hospitals, geothermal and commercial property projects.
Lab Extreme Reliability Tests
We operate a standardized in-house reliability lab to simulate extreme working conditions for electromagnetic heat meters, IoT water meters and regional energy controllers, including temperature cycling, thermal shock, EMC interference, waterproof & dustproof and long-term aging tests. All finished products undergo multiple precision calibrations to control metering errors within strict limits. Standard testing workflows eliminate design and craft defects upfront and reduce late-stage maintenance failures. Rigorous lab testing ensures stable performance under harsh conditions of geothermal stations, hospitals and industrial parks, meeting clients’ long-term demand for high-precision energy metering.
Full-lifecycle Quality Traceability
Tkind builds a closed-loop traceability system covering R&D, production, delivery and after-sales. Each ultrasonic heat meter and energy collector is assigned a unique ID to record component batches, assembly steps, test data and factory calibration records. We integrate on-site maintenance feedback and failure data into QC database to form a continuous improvement loop of problem identification, root cause analysis, craft upgrade and effect verification. Full traceability quickly locates quality defects, optimizes product stability and improves long-term satisfaction for hospital and geothermal clients.
Authorized Third-party Testing
Our core metering products are regularly sent to national metering institutes for official type evaluation. Ultrasonic heat meters, electromagnetic heat meters and IoT thermostats obtain complete metering instrument certifications. Authorized third parties strictly verify metering accuracy, environmental adaptability, EMC performance and service life with official test reports. All released products pass both internal inspection and external authoritative testing. Dual QC guarantees precise and reliable metering data, meeting mandatory testing qualification requirements for bidding of municipal, hospital and geothermal projects.
Scene-oriented Quality Optimization
Based on massive project feedback from hospitals, geothermal stations, smart properties and industrial parks nationwide, Tkind optimizes QC standards for different scenarios: high-temperature and anti-scale testing for geothermal working conditions; enhanced EMC resistance and stable metering for medical buildings; long-term low-power durability tests for commercial properties. We update testing indicators with on-site operation data and customize QC schemes to meet strict industry demands, extending service life and improving metering accuracy under diverse working conditions.
ISO Standardized QC System
Tkind fully implements the ISO9001 quality management system with standardized workflows for document control, staff training, equipment calibration and finished product sampling. All energy metering devices are manufactured in line with national metering instrument standards. We conduct regular internal audits and annual third-party sampling inspections to optimize QC procedures. Compliant quality control guarantees full market access qualifications for heat meters and energy collectors, supporting bidding projects of hospitals, geothermal stations and smart properties nationwide, eliminating compliance risks and consolidating brand credibility.
