CROWCON Equipment We Repair — By Category
CROWCON Product Lines We Repair
Our engineers are trained on the full CROWCON product range. Below are the major product families we service.
Xgard Bright
Portable multi-gas monitor designed for confined space entry and hazard assessment in Indian refineries, chemical plants, and mining operations. Common faults include sensor drift, LCD display degradation, battery charging failures, and bump test communication errors.
Xgard Advanced
High-specification portable detector with advanced datalogging and wireless connectivity for process safety and emergency response teams. Typical issues include Bluetooth module failure, internal memory corruption, calibration offset drift, and connector corrosion.
Gasmaster Automated Systems
Fixed installation gas detection control units and alarm panels for continuous monitoring in hazardous areas. Common repair needs include relay card failure, analog signal conditioning errors, solenoid valve interface faults, and power supply degradation.
Fixed Detector Heads
Catalytic bead and electrochemical sensor modules for LPG, hydrocarbon, oxygen, and toxic gas detection in permanent installations. Typical faults include sensor poisoning, zero drift, slow response time, and electrical connector intermittency.
Signal Conditioners and Transmitters
4-20mA loop powered devices that convert Crowcon detector output into industrial control signals for DCS and PLC integration. Common issues include output scaling errors, loop power supply failures, and signal noise immunity.

Common CROWCON Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CROWCON equipment arriving at our workshop.
- ✓Sensor reading drift or calibration offset — Crowcon sensors experience gradual zero/span drift over 12-24 months in India's humid industrial environments, especially in coastal regions and chemical plants. Exposure to dust, corrosive fumes, or moisture ingress accelerates degradation.
- ✓LCD display pixel failure or complete blackout — Xgard Bright and Advanced units develop display faults due to thermal cycling in Indian climates, vibration exposure during plant transport, or electrostatic damage during maintenance. LCD ribbon cable and driver IC failure are common root causes.
- ✓Battery not charging or rapid discharge — Crowcon portable detectors exhibit charging circuit failures when exposed to high humidity, mineral deposits in charging contacts, or internal battery cell degradation. Indian monsoon climates and inadequate storage conditions accelerate this fault.
- ✓Bump test communication failure — Crowcon bump test protocols depend on stable wireless or IR communication with docking stations. Interference from 2.4GHz sources, firmware version mismatch, or optical sensor obstruction causes repeated test failures in Indian manufacturing plants.
- ✓Fixed head detector slow response or stuck readings — Crowcon fixed detector heads degrade when exposed to process vapors, dust accumulation, or thermal shock in Indian petrochemical and refineries. Catalyst poisoning in catalytic bead sensors and electrode fouling in electrochemical cells reduce response time and accuracy.
- ✓Analog output signal noise or incorrect 4-20mA scaling — Crowcon signal conditioners and transmitters experience EMI-induced noise in DCS/PLC integration due to inadequate shielding near high-power motor drives or unshielded cable runs common in Indian plant environments. Firmware calibration errors cause incorrect current scaling.

Frequently Asked Questions — CROWCON Repairs
Do you repair Crowcon equipment anywhere in India?+
Yes. Synchronics repairs the full Crowcon gas detection product range including Xgard Bright, Xgard Advanced, Gasmaster systems, and fixed detector heads. We offer PAN India door-to-door pickup and return from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all major cities. All repairs are performed in our Vadodara facility with 5-7 day turnaround for standard faults.
Are Crowcon sensor replacements available and certified?+
Yes. Synchronics stocks genuine Crowcon sensor modules including catalytic bead, electrochemical oxygen, and toxic gas sensors. All replacement sensors are sourced from authorized Crowcon distributors in India or UK, come with original calibration certificates, and include fresh expiry dates. Installed sensors are recalibrated and validated before return.
Can you perform bump tests and annual compliance calibration on Crowcon detectors?+
Yes. Synchronics performs ISO 17543 compliant bump testing, full zero/span calibration, and annual compliance verification on all Crowcon portable and fixed detection equipment. We use certified calibration gas mixtures (methane, hydrogen sulfide, oxygen, etc.) and generate compliance documentation required by Indian Factory Acts and DGMS regulations. Bump test certifications are issued within 24 hours.
What happens if a Crowcon detector shows 'Sensor Fault' or 'HW Error' codes?+
These codes indicate sensor degradation, PCB component failure, or firmware corruption. Synchronics diagnoses the root cause using Crowcon service software, performs component-level repair (sensor replacement, capacitor/resistor replacement), or firmware reloads. We validate sensor functionality and error code clearance before release.
Do you offer Crowcon equipment calibration support for Indian pharma and food plants requiring GMP/HACCP compliance?+
Yes. Synchronics provides traceable calibration services with NIST-equivalent standards for Crowcon equipment used in regulated manufacturing. We maintain calibration records, issue audit-ready certificates, and support regulatory inspections by FDA, FSSAI, and local authorities. Our calibration lab is equipped for multi-point linearity verification.
How do I send my CROWCON 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 CROWCON 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 CROWCON 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 CROWCON 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.
