MKS INSTRUMENTS Equipment We Repair — By Category
MKS INSTRUMENTS Product Lines We Repair
Our engineers are trained on the full MKS INSTRUMENTS product range. Below are the major product families we service.
MKS Baratron Pressure Transducers
Precision absolute and gauge pressure transducers for ultra-high vacuum to atmospheric applications. Common failures include zero drift, sensitivity loss, and electrical connector degradation in harsh chemical environments used in semiconductor and analytical labs.
MKS 1179A Mass Flow Controller
Digital mass flow controllers for semiconductor process gases with integrated electronics and fast response times. Repair typically addresses sensor fouling, controller offset errors, and valve actuation faults that degrade setpoint accuracy.
MKS Type 900 Vacuum Gauge Controllers
Multi-channel vacuum measurement and control units for process monitoring. Common issues include sensor interface failures, analog output errors, and loss of vacuum reading after prolonged high-temperature operation in deposition chambers.
MKS Granville-Phillips Convection Gauges
Convection-based vacuum measurement transducers for moderate vacuum monitoring in pump-down applications. Failures often stem from filament burn-out, bridge circuit imbalance, and thermal compensation drift in production environments.
MKS 910 Series Vacuum System Controllers
Integrated pump control and pressure regulation systems for vacuum chamber automation. Repair addresses relay failures, sensor input errors, pump interlock malfunctions, and analog control signal loss.

All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common MKS INSTRUMENTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in MKS INSTRUMENTS equipment arriving at our workshop.
- ✓Baratron transducer zero drift over time — Thermal drift, long-term capacitor aging, and environmental contamination inside the sensor head cause the zero reference to shift, resulting in pressure reading errors of 1-5% FS even when measuring at atmospheric or vacuum baseline.
- ✓MKS mass flow controller setpoint inaccuracy — Sensor fouling from process gas decomposition, thermal interface degradation between flow sensor and electronics module, and loss of factory calibration reference gas baseline cause the controller to read 5-15% low or high of intended flow rate.
- ✓Type 900 vacuum controller analog output failure — Corrosion of signal conditioning PCB traces, failure of precision potentiometer in output scaling circuit, or capacitor leakage in the 4-20mA output stage result in constant, erratic, or no analog signal to recording equipment.
- ✓Granville-Phillips gauge filament burn-out — Overpressure exposure above design limit (filament rupture), electrical surge during connector insertion, or manufacturing defect in the heating filament element causes complete loss of vacuum reading and inability to restart the gauge.
- ✓MKS 910 series pump control relay chatter — Aging contact surfaces in mechanical relays, moisture ingress into relay cavity, or incorrect hysteresis setting in pump start/stop logic cause repeated energize-de-energize cycling that shortens pump life and creates pressure fluctuation.
- ✓Pressure transducer connector corrosion and intermittent signal — Exposure to corrosive process gases, condensation in connector cavity, or poor weatherproofing allows oxidation of gold-plated pins and signal degradation, especially common in semiconductor wet process areas with HF or chlorine exposure.

Frequently Asked Questions — MKS INSTRUMENTS Repairs
Do you repair MKS Instruments equipment anywhere in India?+
Yes. Synchronics repairs the full MKS Instruments product range across India — pressure transducers, mass flow controllers, vacuum gauges, and process control systems. We offer same-day pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all major industrial cities. All repairs are performed at our ISO 9001 certified facility in Vadodara, Gujarat with complete traceability and documentation.
Can you recalibrate MKS Baratron transducers to current manufacturing specs?+
Yes, absolutely. Synchronics maintains certified calibration standards traceable to NIST for pressure measurement across 0.1 torr to 1000 psi range. We recalibrate all Baratron series (223, 225, 627) transducers to ±0.25% full-scale accuracy and issue formal recalibration certificates valid for semiconductor cleanroom documentation. Turn-around is typically 5-7 working days.
What is the typical repair cost for MKS mass flow controller electronics failure?+
MKS mass flow controller repair costs depend on failure type. Sensor fouling and electronics recalibration typically runs Rs. 12,000-18,000. Full module replacement or custom gas mixture re-certification costs Rs. 20,000-35,000. We provide free failure diagnosis and quotation before repair. Many Indian semiconductor fabs choose our repair service over replacement due to 60-70% cost savings and faster turnaround.
Do you stock genuine MKS Instruments replacement parts and sensors?+
Yes. Synchronics maintains stock of common MKS spare parts including Baratron sensor cartridges, mass flow controller thermal elements, vacuum gauge filaments, and relay modules. For specialized or discontinued parts, we source directly from MKS and authorized distributors with lead times typically 2-4 weeks. We always use genuine MKS components to maintain equipment reliability and warranty validity.
Can you repair MKS 910 pump control systems used in our research vacuum chamber?+
Yes. Synchronics specializes in MKS 910 series (910S, 910G, 910M) pump automation and pressure regulation systems. Common repairs include relay replacement, sensor input troubleshooting, pump interlock circuit restoration, and PLC firmware re-initialization. We test all repairs against your specific vacuum chamber load profile and provide system commissioning support at your site if needed.
How do I send my MKS INSTRUMENTS 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 MKS INSTRUMENTS 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 MKS INSTRUMENTS 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 MKS INSTRUMENTS 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.
