TESTO Equipment We Repair — By Category
TESTO Product Lines We Repair
Our engineers are trained on the full TESTO product range. Below are the major product families we service.
TESTO Thermal Imaging Cameras
Portable infrared cameras including testo 869, testo 876, and testo 890 models used for electrical fault detection, building thermal surveys, and predictive maintenance. Common issues include sensor drift, display defects, focus mechanism failure, and internal lens fogging requiring professional recalibration.
TESTO Combustion and Gas Analysers
Portable emission analysers like testo 300, testo 320, and testo 350 used in power plants, refineries, and manufacturing for flue gas testing. Repair focus includes sensor poisoning recovery, zero-span calibration, probe corrosion issues, and sample line blockages common in high-dust Indian industrial environments.
TESTO Digital Multimeters and Clamp Meters
Handheld electrical measurement instruments including testo 755-1, testo 760, and testo 770 clamp meters. Failures include display segment corruption, measurement range selector switch wear, AC/DC conversion circuit faults, and battery charging port issues prevalent in high-humidity Indian industrial settings.
TESTO Indoor Air Quality Monitors
Fixed and portable CO2, temperature, and humidity instruments for pharmaceutical clean rooms, food processing facilities, and building management systems. Repair issues encompass sensor lifetime exhaustion, wireless transmission failure, data logger memory corruption, and display backlighting degradation.
TESTO Food Temperature and Moisture Probes
Specialized measurement instruments for Indian pharmaceutical, dairy, and food processing industries including moisture analysers and penetration thermometers. Common faults involve probe contamination, connector corrosion, battery oxidation, and calibration drift affecting compliance documentation required by Indian regulatory authorities.

Common TESTO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TESTO equipment arriving at our workshop.
- ✓Thermal camera sensor drift and measurement inaccuracy — Extended use in Indian industrial environments with temperature extremes, moisture, and dust contamination causes radiometric calibration to shift, typically 2-5 degrees Celsius error on testo 869/876/890 models after 18-24 months of heavy usage.
- ✓Gas analyser sensor poisoning and zero calibration failure — TESTO combustion analysers deployed in refineries and power plants accumulate particulate contamination and chemical poisoning on electrochemical sensors, especially sulfur dioxide and nitrogen oxide sensors, causing erratic readings and failed zero-span checks.
- ✓Thermal imaging display panel segments non-functional or dimmed — LCD backlighting degradation, flex circuit connector corrosion, and display driver IC failures are common in testo 880-890 cameras used in humid coastal Indian plants and exposed outdoor electrical surveys, rendering the IR image unreadable despite functional sensor.
- ✓Combustion analyser probe tip cracking and measurement dead spots — Testo 300/320/350 ceramic and stainless steel probe tips crack due to thermal shock (rapid cooling in wet flue gas) and corrosive gas exposure. Fine cracks create dead zones where gas sample bypasses sensor elements, producing false low readings.
- ✓Digital clamp meter AC/DC selector switch sticky or non-responsive — testo 760 and testo 770 clamp meters used in Indian switchgear testing accumulate dust and moisture in the rotary function selector switch, causing intermittent contact or complete mode switching failure during power factor and harmonic measurements.
- ✓Thermal camera focus mechanism stuck or slow autofocus — Motor-driven focus rings in testo 876/890 models jam due to dust ingestion and thermal cycling stress on plastic focus gears. Autofocus failure occurs when focusing servo motor loses calibration or internal lens positioning sensor drifts.

Frequently Asked Questions — TESTO Repairs
Do you repair TESTO equipment anywhere in India?+
Yes. Synchronics Electronics repairs the complete TESTO product range — thermal imaging cameras, combustion analysers, gas analysers, clamp meters, and air quality monitors. We offer pan-India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, and all other major cities. All repairs are performed at our Vadodara, Gujarat facility with turnaround time typically 7-10 working days.
How do you recalibrate TESTO thermal imaging cameras for measurement accuracy?+
We recalibrate TESTO 869/876/880/890 thermal cameras using NIST-traceable reference blackbodies maintained in our climate-controlled lab. We perform radiometric calibration across 5 temperature points, verify emissivity compensation, and test thermal sensitivity. Calibration reports are issued with updated factory coefficients valid for Indian regulatory inspections and ISO 9001 quality documentation.
What is the cost and timeline for TESTO combustion analyser sensor replacement?+
Sensor replacement cost for TESTO 300/320/350 analysers typically ranges from INR 8000-15000 depending on sensor type (O2, NO, NO2, CO, or SO2). We source genuine TESTO sensors and complete the repair in 5-7 days including zero-span calibration testing. We provide a 90-day warranty on sensor function.
Can you repair TESTO thermal cameras that have internal condensation or lens fogging?+
Yes. Synchronics disassembles the optical assembly, dries all internal surfaces in a controlled humidity chamber, applies desiccant silica packs, and reseals the camera body with fresh rubber gaskets. We then verify thermal image clarity and perform sensor calibration. This repair typically costs INR 6000-10000 and takes 8-10 days.
Do you supply replacement parts for TESTO instruments or only offer repair?+
We primarily offer full repair and calibration services. However, for critical spares like LCD displays, probe tips, sensors, and battery packs for TESTO 869/876/890/300/320/350 models, we can source genuine OEM components. Contact our Vadodara office for parts availability and lead times — most common spares are stocked and ship within 3-5 days.
How do I send my TESTO 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 TESTO 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 TESTO 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 TESTO 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.
