Measurement is the technical process of quantifying a physical, chemical, or logical quantity by comparing it with a known standard. It is the basis for validating products, processes, and systems — ensuring quality, safety, traceability, and regulatory compliance in industrial, laboratory, and clinical environments.
In practice, there is no reliable test without well-implemented measurement.
Why is measurement essential?
- 📏 Validate technical design requirements
- 🧾 Certify compliance with standards and tolerances
- 📈 Detect variations and keep processes under control
- 🔁 Standardize results and quality decisions
- 📁 Generate traceability for audits and clients
Main types of measurement
🔌 Electrical measurement
Used to verify signals and consumption in electronic systems:
- Voltage, current, resistance, impedance, capacitance
- Performed with multimeters, programmable power supplies, oscilloscopes, LCR meters
- Fundamental for functional tests, ICT, circuit validation, and electrical safety
🌡️ Physico-chemical measurement
Typical in cosmetic, pharmaceutical, and chemical sectors:
- pH, viscosity, conductivity, density, thermal stability
- Executed with sensors in laboratories or attached to automated systems
- Supports stability tests, formula characterization, and packaging compatibility
⚙️ Mechanical and dimensional measurement
Indispensable in parts assembly, machining, and validation of electromechanical systems:
- Distance, angle, thickness, height, displacement, torque, force
- Tools: calipers, micrometers, dial indicators, load cells, strain gauges
- Can be done manually, with digital sensors, or with robotic systems
📶 RF signal and communication measurement
Applied to devices with embedded connectivity:
- Transmitted power, sensitivity, BER, EVM, pairing time
- Specialized equipment like LitePoint, Keysight, Anritsu
- Applications: Wi-Fi, BLE, ZigBee, GNSS, LoRa, RF modules
👁️ Vision measurement (machine vision)
Contactless technology based on industrial cameras and image algorithms for measuring visual parameters with high speed and repeatability.
What can be measured:
- 📏 Dimensions (width, height, angle, edge-to-edge distance)
- 🎯 Position and orientation of parts in assemblies
- 🔤 Reading and validation of markings, texts, and codes (OCR, DataMatrix)
- 🎨 Color, brightness, texture, fill level, presence of visual defects
- 🔍 Presence or absence of elements in a product
Applications with AJOLLY Testing:
- Automated optical inspection of finished products
- Dimensional verification of parts in line
- Aesthetic validation and readability of laser markings
- Visual control of cosmetic application or bottle filling
AJOLLY integrates vision systems with technical lighting, high-resolution cameras, calibrated lenses, and proprietary software with OpenCV, Halcon, or LabVIEW Vision.
