HARSHAW Product Lines We Repair
Our engineers are trained on the full HARSHAW product range. Below are the major product families we service.
Harshaw TLD Reader Systems
Thermoluminescent dosimetry readers for personnel and environmental dosimetry. Common faults include heating element failures, photomultiplier tube degradation, temperature sensor drift, and data acquisition board malfunctions affecting dose accuracy and reproducibility.
Harshaw Scintillation Detectors
Sodium iodide (NaI) and cesium iodide (CsI) crystal detectors used in gamma spectroscopy and radiation surveys. Repair involves PMT replacement, crystal integrity assessment, high-voltage supply failures, and signal processing circuit restoration.
Harshaw Environmental Monitoring Systems
Continuous air monitor and environmental survey instrumentation for nuclear facilities and medical institutions. Typical repairs address sensor fouling, electronics module failures, wireless transmission loss, and calibration drift in India's humid and high-temperature industrial environments.
Harshaw Survey Meters and Dose Rate Instruments
Portable gamma and beta survey meters used for field radiation assessment. Common failures include detector window damage, battery charger circuits, analog display panel faults, and communication interface failures in handheld units.
Harshaw Calibration and Reference Sources
Radioactive reference sources and calibration equipment for maintaining instrument accuracy. Repairs include source holder integrity, shielding assessment, linearity verification, and certification documentation for regulatory compliance.

Common HARSHAW Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HARSHAW equipment arriving at our workshop.
- ✓Photomultiplier tube signal loss or noise — Harshaw detectors use sensitive PMTs exposed to high-voltage stress and thermal cycling in Indian nuclear and medical facilities. PMT photocathode aging, dynode chain contamination, and high-voltage regulator drift cause signal degradation or complete detector failure.
- ✓TLD reader heating element malfunction — Harshaw TLD readers cycle heating elements 50+ times daily for dose readout. Thermal element burnout, thermostat calibration drift, and thermal transfer grease degradation in India's industrial dust environments reduce heating ramp accuracy and compromise dose measurement precision.
- ✓Data acquisition board clock drift or memory corruption — Harshaw's TLD systems and spectroscopy readers use real-time data logging and timestamp functions. Crystal oscillator aging, EEPROM bit rot from thermal stress, and firmware corruption in humid industrial environments cause data loss, timestamp errors, and failed dose records.
- ✓Detector high-voltage supply regulation failure — Harshaw gamma and beta detectors require stable high-voltage (400V-2000V DC). Power supply voltage regulators fail due to thermal stress, capacitor dry-out in India's climate, and transient spikes from facility power fluctuations, causing detector shutdown or unsafe overvoltage conditions.
- ✓Thermoluminescent crystal phosphor degradation or contamination — Harshaw TLD phosphors (LiF, CaSO4) absorb residual radiation and environmental moisture over years of use in nuclear facilities. Fading of stored dose signal, chemiluminescence from dust contamination, and hygroscopic absorption reduce measurement accuracy by 5-15% annually.
- ✓Wireless data transmission loss or authentication failure — Harshaw networked monitoring systems use proprietary wireless or Ethernet protocols for remote dosimetry and environmental data logging. Antenna corrosion, network module firmware bugs, and security certificate expiration cause data gaps in multi-facility monitoring networks typical of India's large nuclear and medical campuses.

Frequently Asked Questions — HARSHAW Repairs
Do you repair Harshaw equipment anywhere in India?+
Yes. Synchronics repairs the complete Harshaw radiation detection and dosimetry portfolio — TLD readers, scintillation detectors, survey meters, environmental monitors, and calibration systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Hyderabad, Bangalore, Chennai, Kolkata, Ahmedabad, and all other cities. All repairs centralized at our Vadodara, Gujarat facility with nuclear-trained engineers and certified test equipment.
Can Harshaw TLD readers be recalibrated after repair?+
Absolutely. Harshaw TLD reader calibration is critical for dose accuracy in medical and nuclear facilities. After component repair, Synchronics performs full system calibration using NIST-traceable cesium-137 and cobalt-60 reference sources. We generate calibration certificates valid for regulatory compliance across India's atomic energy and medical radiation safety authorities.
What is Synchronics' turnaround time for Harshaw detector repair?+
Standard Harshaw repairs — PMT replacement, high-voltage supply restoration, signal circuit repair — are completed in 5-7 working days. Complex spectroscopy system recalibration or multi-module restoration may take 10-14 days. Express 48-hour turnaround available for critical nuclear facility equipment upon request. We prioritize dosimetry continuity for medical and nuclear applications.
Do you handle Harshaw warranty repairs or out-of-warranty equipment?+
Synchronics repairs both warranty and out-of-warranty Harshaw instruments across India. We are authorized to service legacy Harshaw models no longer supported by original distribution, which is common for university labs and smaller medical facilities. We maintain parts inventory and technical documentation for Harshaw equipment manufactured 1990-present.
Can you repair Harshaw environmental monitoring systems used in multi-facility networks?+
Yes. Harshaw continuous air monitors and environmental survey systems are deployed across large nuclear campuses and multi-unit medical centers. Synchronics restores individual monitoring nodes, troubleshoots data aggregation failures, recertifies sensor calibration, and validates wireless/network connectivity to ensure seamless integration with facility monitoring dashboards.
How do I send my HARSHAW 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 HARSHAW 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 HARSHAW 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 HARSHAW 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.
