ORP Meter Price in Bangladesh

ORP meter price in Bangladesh starts from ৳25,000 and goes up to ৳60,000 depending on features like data logging and bench versus portable design. An ORP meter measures the oxidation-reduction potential of water, telling you how effectively it can disinfect itself or break down contaminants. ASTZ supplies genuine Milwaukee and Hanna instruments with full manufacturer warranty, so treatment plants, fish farms, and labs across Bangladesh get accurate readings backed by real technical support rather than unverified imports.

What is an ORP Meter & Why It Matters

An ORP meter measures the electrical potential of water in millivolts (mV), showing whether the water has strong oxidizing or reducing properties. A higher positive reading means the water can neutralize bacteria and contaminants more effectively, which is why treatment plants and pool operators track it closely.

ORP vs pH — What’s the Difference

These two get mixed up constantly, but they measure completely different things. pH tells you how acidic or alkaline water is, while ORP tells you how strong its disinfecting or oxidizing power is. Two water samples can share the exact same pH value yet have very different ORP readings, which is why serious water treatment work checks both parameters rather than relying on pH alone.

How ORP (mV) Readings Are Interpreted

Readings above +650 mV generally indicate strong disinfection capability, often used as a benchmark in swimming pools and drinking water systems. Lower or negative readings suggest reducing conditions, common in stagnant water, wastewater, or anaerobic environments where oxidation activity is minimal.

Best ORP Meters Available at ASTZ

Milwaukee pH58 MAX Waterproof 3-in-1 pH/ORP/Temp Tester – Best Budget Pick

This compact tester covers pH, ORP, and temperature in a single waterproof body, making it the most affordable entry point into ORP testing. It suits small-scale users like home aquarium owners or students who need reliable basic readings without a large investment. [View product details →]

Milwaukee MW105 MAX Waterproof pH/ORP/Temp Portable Meter – Best for Field Use

Built for technicians who move between test sites, the MW105 MAX combines a rugged waterproof housing with dependable pH and ORP accuracy. It’s a solid middle-ground choice for field teams who need more precision than a basic tester offers. [View product details →]

Milwaukee MW106 MAX (with Data Logging) – Best for Continuous Monitoring

The MW106 MAX adds data logging on top of everything the MW105 offers, letting you record readings over time instead of taking one-off spot checks. This makes it valuable for treatment plants and researchers tracking water quality trends across days or weeks. [View product details →]

Milwaukee MW151 pH/ORP/Temp Bench Meter – Best for Lab/Fixed Setup

Designed for fixed lab environments, the MW151 delivers logging capability and stable, repeatable readings for facilities running frequent tests at one location. It’s the right pick when portability matters less than consistent, high-volume testing accuracy. [View product details →]

How to Choose the Right ORP Meter

Portable vs Benchtop ORP Meter

Field technicians and mobile testing teams need a portable meter like the pH58 MAX or MW105 MAX. Labs and treatment facilities running tests at a single fixed location benefit more from a benchtop unit like the MW151.

Data Logging vs Standard Reading — Kobe Dorkar

If you only need occasional spot checks, a standard meter without logging works fine and costs less. Data logging becomes essential when you’re monitoring trends over time, such as tracking disinfection levels across a full treatment cycle.

Waterproof Rating (IP67) — Field Use er jonno kokhon important

Any meter used outdoors near ponds, tanks, or treatment basins should have solid waterproof protection. All four Milwaukee models here are waterproof, but this matters most for field technicians who risk splashes or accidental drops.

Combo (pH+ORP+Temp) vs Dedicated ORP Meter

Most buyers in Bangladesh benefit from a combo meter since pH and temperature readings usually go hand-in-hand with ORP testing. A dedicated ORP-only meter makes sense only for specialized industrial applications where pH is already monitored separately.

ORP Meter Applications in Bangladesh

Drinking Water & WASA Treatment Plants

Treatment facilities use ORP readings to confirm chlorination and disinfection processes are working before water reaches distribution lines.

Aquaculture & Fish Farming (Water Disinfection Monitoring)

Fish farmers monitor ORP to catch declining water quality early, since low oxidation levels often signal rising bacterial load or poor aeration in ponds.

Swimming Pool & Spa Water Quality

Pool operators rely on ORP alongside chlorine levels to confirm water stays properly sanitized without over-dosing chemicals.

Industrial Wastewater Treatment

Factories treating wastewater use ORP monitoring to verify oxidation processes are breaking down contaminants before discharge, helping meet environmental compliance standards.

Replacement Probes & Sensors

Hanna Spare pH/ORP Sensors & Probes — jokhon replacement lagbe

If your existing Hanna meter’s probe wears out or loses accuracy, replacing just the sensor is far more cost-effective than buying a new unit. ASTZ stocks the Hanna HI7609829-10 probe and HI76981941 spare sensor, both compatible with HI769819X series meters, so you can restore full accuracy without replacing your entire setup.
