What We Do
Three Divisions, One Compliance File
Calibration is where we started. Today ION Engineering covers every measurement, validation and statutory test a Bangladeshi plant needs — on one schedule, from one accredited team.
Calibration
Six accredited disciplines, in our laboratory or at your plant — with traceable standards and stated uncertainty on every certificate.
Pharma Validation
GMP qualification and validation with documentation formatted the way DGDA, WHO-GMP and FDA auditors expect to read it.
Safety & Inspection
DIFE enlisted statutory testing and industrial inspection that keeps your plant legal, your buyers satisfied and your people safe.
Calibration Disciplines
Six Disciplines, One Accredited Laboratory
From a pressure transmitter on the shop floor to an analytical balance in your QC lab — every measurement you rely on, calibrated and certified under one accreditation.
Thermal & Humidity Calibration
Temperature indicators, RTD and thermocouple sensors, ovens, furnaces, water baths, BOD incubators, humidity chambers, controllers and data loggers.
Dimension Calibration
Outside, inside, depth and digital micrometers, vernier calipers, dial indicators, bore and thickness gauges, measuring scales, tapes and angle protractors.
Electro-Technical Calibration
Voltmeters, ammeters, wattmeters, frequency meters, multimeters, clamp meters, insulation and earth resistance testers, loop calibrators and power sources.
Mass, Force & Volume Calibration
Analytical balances, platform scales, load cells, E1–M1 standard weights, micropipettes, glassware up to 5000 ml, torque wrenches and hardness testers.
Analytical Instrument Calibration
HPLC, GC, UV spectrophotometers, pH and TDS meters, moisture balances, hydrometers, viscosity cups, test sieves and dissolution apparatus.
