COMARK Product Lines We Repair
Our engineers are trained on the full COMARK product range. Below are the major product families we service.
COMARK Digital Thermometers & Handheld Probes
Portable digital thermometers with interchangeable probes for rapid temperature spot-checking. Common repairs include failed LCD displays, non-responsive buttons, faulty sensor connections, and battery contacts corrosion from humid food processing environments.
COMARK Data Loggers (Wireless & Wired)
Temperature data loggers with cloud connectivity, SD card storage, and wireless transmission. Typical faults include failed Wi-Fi modules, corrupted SD card interfaces, low-battery detection circuits, and timestamp synchronization errors in pharmaceutical cold storage applications.
COMARK RTD Sensors & Thermocouple Probes
Precision resistance temperature detectors (RTD) and thermocouple sensors for industrial temperature monitoring. Repairs focus on corroded connectors, signal conditioning board failures, sheath damage from washdown environments, and calibration drift recovery.
COMARK Temperature Monitoring Transmitters
Wall-mounted and panel-mounted transmitters that convert analog temperature signals to 4-20mA output or Modbus signals. Common issues include input calibration loss, output signal dropout, relay failure in alarm circuits, and power supply instability.
COMARK Cold Chain Tracking Systems
Integrated temperature monitoring for cold storage and frozen goods logistics. Repair demands include GPS module failure, SIM card reader malfunction, alert relay non-response, and firmware update failures during shipment transitions.
Why Choose Synchronics for COMARK Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on COMARK equipment.

Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common COMARK Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in COMARK equipment arriving at our workshop.
- ✓LCD display blank or partial segment failure — Humidity ingress from steam-filled food processing kitchens and cold storage condensation damages LCD driver circuits. COMARK thermometer displays are exposed to condensation cycles that corrode the segment decoder chips.
- ✓Temperature sensor reading drift or complete signal loss — RTD Pt100 sensors in COMARK probes develop resistance shift due to thermal cycling in freezer units. Corrosion of probe stem connectors in wet food processing environments breaks the sensor circuit entirely.
- ✓Wireless data logger loss of WiFi or cellular connectivity — COMARK WiFi modules in TL2000 loggers fail after prolonged exposure to refrigeration unit electrical noise. SIM-based loggers develop power management faults, losing connection to cloud servers mid-shift.
- ✓4-20mA transmitter output stuck at one value or absent — Analog output amplifier circuits in COMARK TMM series fail under load current conditions. Temperature sensor input isolation may fail, causing false readings or complete signal blockage to downstream DCS systems.
- ✓Alarm relay non-response despite high temperature condition — COMARK alarm threshold circuits accumulate dust on relay contacts in powder handling and grain storage facilities. Setpoint memory corruption in firmware prevents alarm triggers even when temperature exceeds programmed limits.
- ✓Data logger SD card read/write failure or file corruption — Improper card ejection during active logging and power loss during data write corrupt the file system on COMARK data loggers. SD card slot mechanical wear occurs from repeated insertion cycles in mobile cold chain applications.

Frequently Asked Questions — COMARK Repairs
Do you repair COMARK equipment anywhere in India?+
Yes. Synchronics repairs the full COMARK product range — digital thermometers, RTD probes, data loggers (WiFi and cellular), temperature transmitters, and cold chain monitoring systems. We offer PAN India door pickup and return from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. All repairs are handled in our Vadodara facility with 180+ experienced technicians.
Can you repair COMARK data loggers after they lose WiFi connection or fail to upload data?+
Absolutely. We repair COMARK TL2000 WiFi loggers and cellular TL3000 units that have stopped connecting to the cloud or failed to sync timestamps. Common causes are WiFi module failure, corrupted firmware, SIM card reader issues, or battery circuit failure. Synchronics diagnoses the root cause, replaces failed boards, restore your WiFi credentials and network settings, and retest full cloud connectivity before return. If you have recorded temperature data trapped in the logger, we can recover it using forensic SD card readers.
How long does COMARK equipment repair take at Synchronics?+
Standard COMARK repairs (thermometer displays, probe connectors, transmitter calibration) take 3-5 working days. Complex diagnostics for data logger firmware or wireless module failures may take 5-7 days. Express turnaround (24-48 hours) is available for critical pharmaceutical or food facility shutdowns. We provide live repair status updates and same-day pickup from Vadodara if needed.
My COMARK RTD probe reads incorrectly in the food processing line. How do you fix calibration drift?+
Synchronics recalibrates COMARK RTD sensors using precision ice-point (0°C) and steam-point (100°C) references traceable to Indian National Standards. We measure the Pt100 resistance at multiple temperatures, adjust the bridge circuit gain, and reprogram offset values into the probe electronics. The corrected probe is returned with a calibration certificate valid for 12 months.
What if my COMARK thermometer is still under warranty but broken?+
If your COMARK equipment is under manufacturer warranty, Synchronics can process it through COMARK UK's warranty repair network or repair it directly and co-ordinate reimbursement with your service contract. We maintain authorized service status with COMARK for Indian customers. Contact our support team with your equipment serial number and purchase documentation.
How do I send my COMARK unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a COMARK drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on COMARK repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your COMARK unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
