NUX HANYOUNG Equipment We Repair — By Category
NUX HANYOUNG Product Lines We Repair
Our engineers are trained on the full NUX HANYOUNG product range. Below are the major product families we service.
Temperature Controllers (TH Series)
Compact PID temperature controllers with relay/SSR outputs and multiple input types. Common faults include setpoint drift, thermocouple open-circuit errors, and display segment failures. NUX HANYOUNG TH-series controllers require precise calibration verification post-repair.
Digital Panel Meters (DM Series)
Multi-function digital displays for voltage, current, frequency, and process signals. Repair focus includes LCD degradation, input terminal corrosion, and analog-to-digital conversion errors common in dusty Indian manufacturing environments.
Process Transmitters (PT Series)
Industrial transmitters for temperature, pressure, and strain measurement with 4-20mA or digital output. Failures often involve sensor bridge imbalance, signal conditioning circuit degradation, and connector corrosion in chemical/textile plants.
Multifunction Monitors (MP Series)
Advanced monitoring units with multiple sensor inputs, data logging, and event recording capability. Common issues include memory corruption, real-time clock battery failure, and Modbus communication errors in networked production systems.
Data Loggers (DR Series)
Standalone and networked data acquisition devices for long-term process monitoring. NUX HANYOUNG DR-series loggers experience SD card interface failures, voltage regulator degradation, and calibration offset accumulation over extended use.

Common NUX HANYOUNG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in NUX HANYOUNG equipment arriving at our workshop.
- ✓Temperature display shows ERR or drifts uncontrollably — NUX HANYOUNG temperature controllers TH-series experience calibration offset due to internal reference voltage drift and thermocouple connector oxidation in humid Indian factory environments. Thermal cycling in non-climate-controlled plants accelerates reference capacitor aging.
- ✓Digital panel meter LCD shows partial or missing segments — NUX HANYOUNG DM-series meters suffer LCD segment failure due to moisture ingress through worn gaskets and dead pixel accumulation from extended temperature cycling. Dust infiltration in cement, textile, and sugar plants accelerates LCD degradation.
- ✓Transmitter output signal stuck or intermittent 4-20mA — NUX HANYOUNG PT-series transmitters develop signal conditioning circuit faults when sensor bridge balance drifts due to resistor tolerance shifts and connector corrosion in chemical/pharmaceutical environments. Power supply regulation failures also cause signal collapse.
- ✓Multifunction monitor Modbus communication fails or timeouts — NUX HANYOUNG MP-series monitors experience communication failures due to RS-485 termination resistor degradation, microcontroller firmware corruption from power surges, and connector pin corrosion in electrical cabinet environments. Industrial EMI and voltage transients damage isolation circuits.
- ✓Data logger stops recording or loses time synchronization — NUX HANYOUNG DR-series loggers fail when SD card interface develops read/write errors, real-time clock battery depletes, or microcontroller memory sectors corrupt. Extended operation without power backup and temperature fluctuations age the coin-cell battery prematurely.
- ✓Controller relay output chatters or fails to switch load — NUX HANYOUNG TH-series relay outputs fail due to contact wear from high-frequency switching, coil insulation breakdown in humid environments, and output driver IC failure from transient voltage spikes. Overloaded relay contacts cause arcing and contact fusion.

What calibration standards does Synchronics use for NUX HANYOUNG temperature controllers?+
Synchronics calibrates all NUX HANYOUNG TH-series temperature controllers against NIST-traceable dry-block calibrators and precision RTD references. We verify PID response, setpoint accuracy within ±0.5 degrees C, and sensor linearization across the full input range. Calibration certificates are provided with every temperature controller repair.
Can Synchronics recover data from a failed NUX HANYOUNG data logger SD card?+
Yes. Synchronics has specialized data recovery capability for NUX HANYOUNG DR-series loggers with corrupted SD cards or failed controller boards. We can extract logged data using hardware bypass techniques, reconstruct partial records, and deliver data in Excel or CSV format. Contact our service team for assessment and timeline.
How quickly can Synchronics repair a NUX HANYOUNG multifunction monitor with Modbus communication error?+
Most NUX HANYOUNG MP-series Modbus faults are diagnosed and repaired within 3-5 working days. We perform initial RS-485 interface diagnostics, firmware verification, and protocol testing same-day. If components require replacement, we source genuine NUX HANYOUNG spares and complete turnaround within one week from receipt.
Does Synchronics provide preventive maintenance service for NUX HANYOUNG instrumentation installed in textile and chemical plants?+
Yes. Synchronics offers annual preventive maintenance contracts for NUX HANYOUNG equipment in high-humidity or corrosive environments. We clean connectors, verify calibration drift, test relay contacts, and replace gaskets before failure occurs. Textile dye houses and chemical plants in Gujarat, Maharashtra, and Tamil Nadu benefit from our on-site maintenance visits.
How do I send my NUX HANYOUNG unit for repair?+
