Measuring instrument supplier in Bangladesh

Buying measuring instruments and meters in Bangladesh

Textile and dyeing mills, effluent treatment plants, boiler houses, water suppliers, food and pharmaceutical plants, laboratories and maintenance teams in Dhaka, Gazipur, Narayanganj, Savar and Chattogram buy instruments to measure flow, pH, conductivity, temperature, pressure and level. Readings run processes, show effluent quality and support ISO 9001 audits, so the calibration certificate matters as much as the instrument.

A measuring instrument supplier in Bangladesh often quotes a model number. What you need is the right range, wetted materials, output and certificate for your process. Tell us the medium, the pipe or tank, the range and the signal. We source from verified sellers, check datasheets and calibration certificates, and deliver. The seller commissions inline meters on site. You deal with Roptan only.

What to tell a measuring instrument supplier in Bangladesh

Medium and conditions

Name the liquid, gas or surface, its temperature and pressure, and whether it is corrosive, dirty or foaming. That sets the sensor type and wetted materials.

Range and units

Give normal and maximum values in the units you use, such as bar, kPa, m3/h or °C. For gauges, pick a range so steady pressure stays within about three quarters of full scale.

Pipe or tank details

For flow meters, give pipe size and material and confirm the pipe runs full; follow the maker's straight-run figure for the chosen model. For level, give tank height, shape and fittings.

Output and power

Say whether you need a local display, a 4 to 20 mA signal to a PLC, or a logger. Field points on a 24 V loop need a stable supply, surge protection and good earthing.

Heat, humidity and wash-down

Summers reach 38 to 41 °C and July humidity 94 to 100 percent. Specify IP65 or IP67 housings and proper cable glands for outdoor, effluent and wash-down areas.

Calibration certificate

Ask for a certificate traceable to SI units from a laboratory accredited to ISO/IEC 17025, with the calibration points and uncertainty you need.

Trade or plant use

Say if the meter is used for billing or trade. BSTI's verification and stamping schedule lists water, flow and energy meters and pressure gauges, so ask whether it applies to that use.

Calibration, standards and paperwork for instruments

ISO/IEC 17025 and BAB accreditation

The Bangladesh Accreditation Board accredits calibration laboratories to ISO/IEC 17025 and has been an ILAC MRA signatory for calibration since 29 June 2015, so its certificates are recognised abroad.

BSTI metrology

BSTI's metrology wing and its National Metrology Laboratory calibrate measuring devices to the SI. In September 2025 BSTI cut its calibration fees by about half on average.

Weights and Measures Rules

The verification and stamping schedule lists thermometers, water, gas, liquid, flow and energy meters and pressure gauges. Ask whether it applies where a meter is used for trade or billing.

ISO 4064 for water meters

Covers meters for cold potable and hot water, harmonised with OIML R 49:2013. Meters are rated by permanent flowrate Q3 and the ratio R = Q3/Q1.

IEC 60751 and EN 837-1

IEC 60751 sets tolerance classes for Pt100 sensors, such as F0.15; EN 837-1 covers Bourdon tube pressure gauges and their accuracy classes.

What moves the price of a measuring instrument

• Measuring principle: electromagnetic, ultrasonic and radar instruments cost more than mechanical meters, floats and dial gauges.
• Accuracy: tighter tolerance classes, a higher R ratio on water meters and lower uncertainty cost more.
• Wetted materials: PTFE, PVDF or stainless steel parts for corrosive liquids add to the price.
• Output and display: transmitters with 4 to 20 mA output, loggers and remote displays cost more than local gauges.
• Housing: IP65 or IP67 housings, hazardous-area builds and long cable runs raise the price.
• Calibration: a multi-point certificate from an accredited laboratory costs more than a maker's test sheet, and carries weight in audits.

Lead times and delivery

Instruments in stock in Bangladesh can ship quickly. Large flow meters, radar level sensors and special ranges or materials are often imported to order, so build time, sea transit and clearance at Chattogram port add time, and a local calibration certificate adds its own turnaround. Roptan confirms dates and any minimum quantity in the quote.

We deliver across Bangladesh, from Gazipur to Khulna. Handheld and bench meters arrive tested with their certificates, as do bench instruments such as digital storage oscilloscopes, chosen by bandwidth, sample rate, channels and probes. For inline meters, transmitters and level sensors, the seller installs, wires and commissions them and checks the signal at your panel. You receive certificates, manuals, the warranty and a VAT invoice (Mushak 6.3).

What we check for this order

• Trade licence and import documentsA current licence in the quoted name and import papers for the instruments, so the VAT invoice and warranty come from the business you pay.
• Brand authorisation or stated originThe maker's authorisation, or the origin stated plainly, with the exact model checked against its datasheet for range, materials and output.
• Calibration and spares in BangladeshWho recalibrates and repairs the instrument here, and who holds electrodes, buffer solutions, probes and seals, so one failure does not stop the process.
• Warranty in writingPeriod, what is covered, and exclusions such as broken electrodes or wrong installation, written into the quote.
