TSI Equipment We Repair — By Category
TSI Product Lines We Repair
Our engineers are trained on the full TSI product range. Below are the major product families we service.
Condensation Particle Counter (CPC) Series
TSI CPC instruments detect ultrafine particles down to 4nm. Common failures include condenser saturation, optics contamination, photodiode sensor drift, and firmware corruption. Critical for cleanroom monitoring in pharma and microelectronics.
Optical Particle Counter (OPC) Series
TSI OPC devices measure 0.3-10µm particles via light scattering. Repair needs include laser module decay, PMT tube failure, optical window fogging, serial communication loss, and flow sensor blockage affecting particle counting accuracy.
Air Velocity and Flow Measurement
TSI VelociCalc, Alnor, and hot-wire anemometer systems measure air velocity, volume flow, and environmental parameters. Common issues: probe sensor oxidation, calibration drift, display pixel failure, battery management faults, and wireless connectivity drop.
Environmental and Cleanroom Monitors
TSI AeroTrack and environmental monitors provide real-time particle, temperature, humidity, and pressure data for ISO cleanroom classification. Faults include sensor calibration loss, data logging corruption, Ethernet/Modbus communication errors, and LCD degradation.
DustTrack and Portable Aerosol Monitors
Handheld TSI monitors for occupational health, industrial hygiene, and field sampling. Repair issues: optical sensor contamination from dust ingestion, battery charging circuit failure, touch screen unresponsiveness, and PM data export errors.
Why Choose Synchronics for TSI Repairs?
PCB-Level Expertise

Fast Turnaround
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 — Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common TSI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TSI equipment arriving at our workshop.
- ✓Particle counter zero-baseline drift above threshold — TSI optical sensors (photodiode, PMT) degrade or condenser saturation in CPC models causes false counts. Ambient contamination and operating hours accumulate optical noise floor.
- ✓No communication / serial port timeout errors — TSI instruments communicate via RS-232, USB, or Ethernet. Connector corrosion, firmware communication stack failure, or host interface board component failure (capacitors, isolators) interrupt data transmission.
- ✓LCD display dim, pixels dead, or no display output — TSI panel displays use CCFL or LED backlights that degrade over 5-10 years. Contrast control circuits fail, polarizer layers separate, or driving transistors short out on the display PCB.
- ✓Flow sensor blockage / unreliable flow measurement — TSI flow measurement paths (in CPCs, OPCs, environmental monitors) become clogged with dust, salt nuclei, or water vapor condensate. Pressure transducers measure incorrect flow, triggering false alarms and counting errors.
- ✓Calibration data loss / instrument reads default/zero values — TSI instruments store calibration coefficients in EEPROM or flash memory. Battery-backed RAM fails, EEPROM corruption occurs due to power surges, or firmware upgrade errors wipe calibration tables.
- ✓Battery charging circuit fails / instrument won't power on — TSI portable monitors use lithium or NiMH batteries. Charging ICs overheat or fail due to thermal stress, shorted battery cells cause brownout protection, or main power supply regulators degrade in lab instruments.

Frequently Asked Questions — TSI Repairs
Do you repair TSI equipment anywhere in India?+
Yes. Synchronics repairs the full TSI product range — particle counters (CPC, OPC), flow meters, environmental monitors, and portable aerosol instruments. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. Central repair facility in Vadodara, Gujarat. Fast turnaround for critical cleanroom and pharma operations.
My TSI particle counter shows 'Cal Error' or wildly high zero-baseline — can you fix it?+
Yes. TSI CPCs and OPCs drift when condenser saturation occurs (CPC) or photodiode/PMT sensors age. Synchronics cleans condensers, replaces optical sensors, recalibrates against certified reference aerosols (FDA/NIST traceable), and restores zero-baseline to <1 count/cm3. Turnaround typically 5-7 days. Certificate of calibration provided.
What is your warranty on TSI repairs?+
Synchronics offers 12 months comprehensive warranty on all TSI repairs covering parts, labor, and re-repair if faults re-occur within warranty. For sensor calibration work, we provide 6-month stability guarantee backed by repeat calibration if drift exceeds 5% NIST tolerance.
Can you repair TSI instruments used in ISO Class 5-7 cleanrooms or pharma validation?+
Absolutely. Synchronics specializes in TSI monitor repair for pharma GMP and semiconductor ISO cleanroom environments. All repairs comply with cleanroom particle contamination protocols. We provide documentation, calibration certificates, and traceability records required for regulatory audits and ISO 14644 certification.
Do you stock TSI spare parts and sensors?+
Yes. Synchronics maintains stock of common TSI replacement modules — optical sensors, flow transducers, LCD panels, battery packs, connector assemblies, and firmware libraries. For unavailable OEM parts, we source compatibles or reverse-engineer solutions. Lead time typically 3-5 days. Urgent request premium available.
How do I send my TSI 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.
What is the cost of repairing a TSI 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 TSI 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 TSI 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.
