HOWELL INSTRUMENTS Product Lines We Repair
Our engineers are trained on the full HOWELL INSTRUMENTS product range. Below are the major product families we service.
Howell Panel Meters (Analog)
Ruggedized analog panel meters for voltage, current, frequency and power measurement in harsh industrial environments. Common issues include meter coil damage from overload, zero shift from mechanical shock, and scale pointer misalignment affecting readability.
Howell Digital Meters & Displays
LED and LCD digital instrumentation for temperature, pressure and process variable indication. Typical faults include display segment failure, input amplifier drift, and connector corrosion in humid or chemically aggressive plant environments.
Howell Temperature & Process Controllers
Compact PID controllers and thermostat modules for furnace, kiln and reactor temperature control. Common failures involve thermocouple input circuit degradation, relay contact wear, and setpoint drift causing batch quality variations.
Howell Transducers & Signal Conditioners
Current and voltage transducers for measurement isolation and signal conversion in power monitoring systems. Repair challenges include capacitor aging, isolation transformer degradation, and output scaling errors under heavy industrial vibration.
Howell Chart Recorders & Analog Loggers
Pen chart and digital recording systems for process trend documentation in foundries, heat treatment and chemical plants. Frequent issues are drive motor failure, pen mechanism stiction, and timing circuit drift affecting data accuracy.

Common HOWELL INSTRUMENTS Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HOWELL INSTRUMENTS equipment arriving at our workshop.
- ✓Analog meter pointer sticks or drifts slowly — Howell analog meters develop bearing friction from dust ingress in mill and foundry environments, or the meter movement becomes magnetized causing nonlinear response. Mechanical shock can also bend the pointer pivot.
- ✓Digital display segments missing or intermittent — Howell LED/LCD displays fail due to solder joint cracking on the display module from thermal cycling in foundries and kiln rooms, or LED segment driver IC failure from overvoltage transients.
- ✓Temperature controller output relay chattering or stuck — Howell PID controllers experience relay contact erosion and pitting from switching high inrush currents, or the coil becomes weak due to potting compound moisture absorption and wire insulation breakdown.
- ✓Transducer output signal drifting or noisy — Howell transducers drift when capacitors in the isolation and output conditioning circuits age and degrade — common in high-temperature plant rooms. Connector corrosion also introduces noise into the analog signal path.
- ✓Chart recorder motor runs but pen does not advance — The pen drive mechanism in Howell recorders becomes stiff from dried ink, lubricant gumming, or broken gear teeth in the advance motor coupling. Belt or pulley misalignment can also prevent smooth pen motion.
- ✓Meter reads zero or full scale regardless of input — Input amplifier circuit failure in Howell meters — typically from blown coupling capacitors or failed input buffer IC. Defective input terminals also prevent signal entry.

Frequently Asked Questions — HOWELL INSTRUMENTS Repairs
Do you repair Howell Instruments equipment anywhere in India?+
Yes. Synchronics repairs the full Howell Instruments product range including analog meters, digital controllers, transducers, and chart recorders. We offer PAN India door pickup service from Mumbai, Delhi, Pune, Bangalore, Chennai, Hyderabad, Ahmedabad, and all other major industrial cities. Equipment is brought to our Vadodara, Gujarat facility for complete diagnosis, repair and calibration.
How do you calibrate Howell meters and controllers after repair?+
Synchronics uses precision signal generators, decade boxes, and NIST-traceable calibration standards to restore Howell equipment to factory specifications. We perform multi-point calibration across the full operating range, document all adjustments, and issue a calibration certificate with before/after readings. Repeatability is verified across ambient temperature extremes.
What is the typical turnaround time for a Howell controller or meter repair?+
Most Howell Instruments repairs are completed within 7-10 working days from receipt at our Vadodara facility. Urgent repairs can be expedited to 3-5 days. Complex issues like complete drive circuit failures may require 10-14 days for sourcing replacement modules. We provide daily status updates and free courier pickup/return across India.
Can you repair Howell transducers and signal conditioners with isolation modules?+
Yes. Synchronics specialises in repairing Howell isolation transformers, signal conditioning circuits, and multi-input transducer modules. We recalibrate zero and span offsets, test isolation voltage withstand, verify output accuracy under full-scale load conditions, and inspect potted components for moisture damage using non-destructive methods.
Do you stock spare Howell Instruments components and modules?+
Yes. Synchronics maintains inventory of common Howell replacement modules including display panels, relay packs, capacitor banks, and connector sets. For obsolete or custom Howell components, we can source directly from the manufacturer or recommend equivalent industrial-grade substitutes with full compatibility verification.
How do I send my HOWELL 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 HOWELL 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 HOWELL 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 HOWELL 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.
