EXPLORANIUM Product Lines We Repair
Our engineers are trained on the full EXPLORANIUM product range. Below are the major product families we service.
GR-135 Portable Gamma-Ray Spectrometer
Battery-operated field instrument for real-time gamma-ray analysis in geophysical and environmental surveys. Common issues include detector sensitivity drift, PMT high-voltage instability, and data logger memory corruption affecting spectral storage.
GR-310 HPGe Spectrometer System
High-purity germanium detector system for precise isotope identification and quantitative analysis. Typical faults include cryogenic cooling system failures, detector leakage current rise, and digital pulse processor (DPP) module degradation.
GR-320 NaI Scintillation Spectrometer
Sodium iodide crystal-based spectrometer for portable and fixed laboratory applications in environmental and industrial monitoring. Common failures include photomultiplier tube (PMT) darkening, analog-to-digital converter (ADC) nonlinearity, and crystal optical coupling degradation.
Portable Survey Meters (GR-100 Series)
Handheld radiation survey instruments used for field contamination assessment and occupational safety monitoring. Repair focuses on detector window integrity, battery connector corrosion, and LCD display malfunction.
Multi-Channel Analyzer (MCA) Electronics
Digital signal processing modules that amplify, digitize, and sort gamma-ray pulses into energy spectra. Frequent issues include analog preamp noise injection, timing pulse loss, and firmware version incompatibility with field data.

Common EXPLORANIUM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in EXPLORANIUM equipment arriving at our workshop.
- ✓Photomultiplier tube (PMT) gain loss and darkening — Extended field use in high ambient temperatures or humidity causes photocathode degradation and internal gas contamination in Exploranium GR-135 and GR-320 systems. PMT vacuum seal weakening accelerates this failure, reducing detection efficiency by 30-50%.
- ✓NaI scintillation crystal optical coupling loss — Thermal cycling, vibration during transport, and humidity ingress degrade the optical grease coupling between the crystal and PMT faceplate in Exploranium GR-320 instruments, causing signal attenuation and spectrum baseline shift.
- ✓Cryogenic cooling system compressor failure (GR-310 HPGe) — Mechanical wear in Stirling-cycle coolers used in Exploranium GR-310 systems after 5000+ operating hours causes compressor piston seizure, loss of helium coolant circulation, and HPGe detector warming above safe operating temperature (-90°C), resulting in unacceptable leakage current (>100 nanoamps).
- ✓Multi-Channel Analyzer (MCA) analog-to-digital converter (ADC) nonlinearity — Thermal drift, component aging, and insufficient input signal conditioning in Exploranium MCA modules cause energy-to-channel mapping errors, leading to spectral peak shifts (up to 20-30 channels) and quantification inaccuracy in isotope analysis workflows.
- ✓Data logger memory corruption and spectral file loss — Sudden power loss, firmware bugs, and flash memory cell wear in Exploranium GR-135 and portable survey meters corrupt binary spectral data files, rendering field measurements unrecoverable and disrupting continuous monitoring records.
- ✓High-voltage supply instability and PMT bias drift — Degraded high-voltage power supply circuits in Exploranium detectors cause PMT bias voltage fluctuations (±50V swing), leading to gain variation, baseline noise, and reduced detector linearity across the energy spectrum.

Frequently Asked Questions — EXPLORANIUM Repairs
Do you repair Exploranium equipment anywhere in India?+
Yes. Synchronics repairs the full Exploranium product range — portable spectrometers (GR-135 series), laboratory systems (GR-310, GR-320), survey meters, and multi-channel analyzers. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, and other major cities. All repairs are completed in our certified laboratory facility in Vadodara, Gujarat, with IAEA-compliant calibration.
Can you recalibrate Exploranium gamma-ray spectrometers to international standards?+
Yes. Synchronics maintains a complete set of IAEA-certified radioactive calibration sources (Cs-137, Co-60, Am-241, U-235) and performs full energy and efficiency calibrations for all Exploranium models. We issue traceable calibration certificates with uncertainty quantification (typically 2-3%) and provide documentation suitable for regulatory audits by the Atomic Energy Regulatory Board (AERB) and mining authorities.
What is the turnaround time for GR-310 HPGe detector repairs?+
GR-310 HPGe system repairs typically require 10-15 working days, depending on the extent of cryogenic cooler replacement and detector reconditioning. We prioritize rapid turnaround for critical mining and ONGC operations. Expedited service (7 days) is available for customers with service contracts. All work includes 48-hour stability testing before return shipment.
Do you offer field-level diagnostics for Exploranium instruments without bringing them to Vadodara?+
Yes. Our mobile service engineers can perform on-site diagnostics for GR-135, GR-320, and survey meter issues at mining sites, exploration camps, and laboratories across India. If field-level repair is not feasible, we arrange secure courier logistics to our Vadodara facility. This hybrid approach minimizes downtime for large-scale exploration and monitoring operations.
Can you repair Exploranium systems affected by humid or dusty field conditions?+
Absolutely. Exploranium instruments deployed in India's monsoon regions and arid mining zones often suffer connector corrosion, moisture ingress, and dust contamination. Synchronics specializes in remedial cleaning, conformal coating, connector refurbishment, and environmental sealing to restore field-hardened reliability. We also recommend preventive maintenance protocols for challenging Indian climates.
How do I send my EXPLORANIUM 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 EXPLORANIUM 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 EXPLORANIUM 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 EXPLORANIUM 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.
