Industrial Equipment Testing & Electronic Calibration UAE | Mechore
Inaccurate sensors cause machines to behave unpredictably: triggering false alarms, wasting energy, or running out of safe limits without anyone knowing. Mechore provides electronic testing and calibration for industrial instruments, sensors, and control systems, restoring accuracy and preventing the faults that start here.

Is This Happening to You?
Is Your Equipment Sending the Wrong Signals?
When equipment behaves erratically: unexpected shutdowns, false alarms, readings that don’t match physical conditions. the instinct is to look at the machine. But very often, the machine is fine. The problem is the instruments telling the machine what’s happening.
A pressure sensor reading 10% high causes a system to operate differently from how it was designed. A temperature transmitter with drift causes HVAC to run harder than needed. A load cell that’s lost calibration causes a weighing system to overcharge or undercharge, with real commercial consequences.
Calibration is not glamorous maintenance. But its absence causes problems that look like machine failures and get treated as machine failures, when the fix is much simpler.
Our Testing & Calibration Services
Accurate Instruments. Reliable Systems. Fewer Surprises.
Service 1: Sensor Calibration
Temperature sensors, pressure transmitters, flow sensors, level sensors, and humidity transmitters all drift over time. We calibrate against traceable references and restore accuracy to the instrument’s specified range.
- Temperature sensor and thermocouple calibration (PT100, PT1000, Type K, J, T)
- Pressure transmitter calibration (gauge, absolute, differential)
- Flow sensor verification and calibration
- Level sensor and float switch calibration
- Humidity and CO2 sensor calibration
- 4–20mA loop verification
Service 2: Load Cell & Weighing System Calibration
Load cells in weighbridges, batching systems, and conveyor belt scales are measurement-critical. We calibrate load cells and full weighing systems, correct span errors, and verify linearity across the measurement range.
- Individual load cell calibration
- Multi-cell system calibration and corner adjustment
- Weighbridge and platform calibration
- Batching and dosing system verification
- Summing box and indicator calibration
Service 3: Control System & PLC I/O Testing
Analogue I/O cards in PLCs and controllers pass measurement signals from the real world to the control logic. If these are out of calibration, the controller acts on wrong data. We test and verify analogue I/O accuracy.
- Analogue input calibration (mA, voltage, resistance)
- Analogue output verification
- Signal conditioning circuit testing
- Thermocouple and RTD input card calibration
Service 4: Electronic Component Testing
Before a repaired or suspect electronic component is reinstalled, it should be tested. We carry out component-level testing: capacitors, MOSFETs, IGBTs, diodes, transformers with documented results.
- Capacitor ESR and capacitance testing
- MOSFET and IGBT static testing
- Diode and rectifier testing
- Transformer winding resistance and insulation testing
- Relay contact resistance and operating voltage testing
Service 5: Insulation & Electrical Testing
Insulation faults in wiring and motor windings are among the most dangerous and damaging electrical failures. We carry out insulation resistance testing, continuity testing, and earth bonding verification.
- Insulation resistance (Megger) testing
- Motor winding insulation testing
- Cable insulation and continuity testing
- Earth bonding and continuity verification
- Hi-pot (high potential) testing where applicable
Service 6: Preventive Diagnostic Inspection
A scheduled electronic health check of your equipment: carried out before failure, not after identifies deteriorating components, calibration drift, and developing faults before they cause downtime.
What a preventive diagnostic inspection includes:
- Visual inspection of all PCBs, wiring, and connectors
- Capacitor ESR and condition testing
- Power supply voltage and ripple measurement
- Sensor signal verification
- Fan and cooling system check
- Thermal imaging of loaded electronics (where applicable)
- Written inspection report with condition assessment and recommendations
 The Hidden Cost
Equipment Running on Wrong Data Is Always More Expensive Than You Think
Calibration checks are rarely urgent. When everything seems to be working, it’s easy to defer. But sensors drift continuously, and control systems act on what they’re told. The cost of calibration drift is mostly hidden; it shows up as energy waste, product quality variation, premature wear, and eventually, a failure that looks sudden but has been building for years.
A scheduled inspection programme costs a fraction of an emergency repair and far less than the operational losses from a system running on inaccurate data.
- “A pressure transmitter 15% out of calibration will cause a compressor to work harder than needed, every hour it runs.”
- “A temperature sensor 8°C high in an HVAC system can cost significantly more in energy per year than a calibration check.”
Structured Prevention
Stop Fixing Failures. Start Preventing Them.
For facilities and equipment operators who want to reduce unplanned downtime, Mechore offers scheduled preventive diagnostic inspection programmes. We work with your maintenance schedule to carry out electronic health checks at defined intervals; quarterly, semi-annually, or annually, depending on the equipment criticality and operating environment.
What you get from a programme:
- Scheduled visits with no administrative burden on your team
- Consistent inspection coverage across your equipment
- Written inspection reports for every visit, retained for your records
- Early identification of deteriorating components before failure
- Priority response if a fault is identified during inspection
Contact us to discuss a programme tailored to your facility size and equipment mix.
FAQs
Questions About Testing & Calibration
Signs include: readings that don’t match known physical conditions, instrument drift compared to a reference, equipment behaving differently than expected, or simply time elapsed since the last calibration. For process-critical instruments, annual calibration is a minimum.
In most cases, yes. Many sensors and transmitters can be calibrated in-situ with a reference instrument. Some require removal for full calibration, we advise per instrument type.
Yes. Calibration work includes a written calibration record showing before and after values, the reference standard used, and the calibration date. Formal certificates to specific standards are available, discuss your requirements with our team.
This depends on the equipment, its environment, and how critical it is to your operations. High-criticality equipment in harsh environments (heat, dust, moisture) benefits from more frequent checks. We advise on the right interval when we assess your situation.
In most cases, yes calibration can be carried out at a quiet period in your operations without removing the weighbridge from service. We coordinate with you on timing.
CONCLUSION
Accurate Instruments. Predictable Systems. Fewer Emergency Calls.
Whether you need a single sensor calibrated or a preventive inspection programme for your whole facility, we’ll work with your schedule and your requirements.
