Lutron PDO-519 Dissolved Oxygen Meter Price in Bangladesh

The Lutron PDO-519 Dissolved Oxygen Meter is priced at ৳21,000 at astzbd.com, and this genuine Taiwan-manufactured pen-style meter earns that price through daily-use reliability rather than lab-bench complexity. If you’ve been comparing a Digital Dissolved Oxygen Meter for regular fieldwork against something built for occasional lab use, the Lutron PDO-519 Dissolved Oxygen Meter stands out for one simple reason — it’s designed to be picked up, used one-handed, and put back in a bag or pocket without any setup fuss.

Lutron PDO-519 Full Specification

Lutron PDO-519 Overview – Pen-Style Precision for Everyday DO Monitoring

The Lutron PDO-519 Dissolved Oxygen Meter takes the accuracy expected from a proper DO instrument and packs it into a slim, pen-shaped body you can operate with one hand while holding a sample container with the other. This isn’t a scaled-down toy version of lab equipment — it delivers ±0.1 mg/L accuracy on dissolved oxygen readings using a genuine polarographic oxygen electrode, precise enough for serious daily monitoring work across fish farms, treatment plants, and school labs alike.

Pen Type Portable DO Meter – What Sets This Design Apart

Single-Hand, Pen-Body Ergonomics

At just 180mm long and built with heavy-duty ABS plastic housing, the pen-body shape means you’re not juggling a bulky case and separate probe — the polarographic sensor sits right at the tip, ready to dip into a sample the moment you power on the Lutron PDO-519 Dissolved Oxygen Meter.

Dual-Function LCD (DO + Temperature Simultaneously)

The 29mm x 28mm display shows dissolved oxygen and temperature readings together, so you’re not toggling between screens to get the full picture of a water sample’s condition.

IP-65/IP-67 Splash & Immersion Protection

Rated IP-65 across its full 0–50°C operating range and IP-67 up to 30°C, the Lutron PDO-519 Dissolved Oxygen Meter tolerates the splashes and accidental dips that come with fieldwork near ponds, tanks, and treatment channels.

Digital Dissolved Oxygen Meter Functions Built Into the PDO-519

MAX/MIN/AVG Memory Recall

Rather than jotting down every reading by hand, the built-in memory recall tracks maximum, minimum, and average values automatically — useful when you’re monitoring oxygen fluctuation across a testing session with the Lutron PDO-519 Dissolved Oxygen Meter.

Data Hold for Stable Field Readings

Pressing the HOLD button freezes the display the instant you get a stable reading, which matters when you’re working in bright outdoor light or need to record a number before the probe moves.

Auto Power-Off Battery Management

An automatic shut-off feature conserves the four AAA batteries between uses, though you can still power off manually the moment you’re done testing with the Lutron PDO-519 Dissolved Oxygen Meter.

Lutron PDO-519 vs Lutron DO9100 – Two Different Tools for Two Different Jobs

These two Lutron instruments aren’t competing for the same job — the Lutron PDO-519 Dissolved Oxygen Meter is built for someone who needs a fast, reliable reading on the move, while the Lutron DO9100 Dissolved Oxygen Meter suits a lab environment where extended testing protocols matter more than pocket portability. If your work is mostly field-based, the PDO-519 is the practical choice; if you’re running a fixed lab setup, the DO9100 is worth a separate look.

Portable DO Meter Price in Bangladesh

The Portable DO Meter price in Bangladesh for the Lutron PDO-519 Dissolved Oxygen Meter is ৳21,000 at astzbd.com, reflecting genuine Taiwan manufacturing with a full accuracy specification rather than an unverified import of uncertain calibration.

What Affects the Price

Probe accuracy, IP protection rating, and memory/data-hold functions all add real engineering cost — a pen meter with genuine ±0.1 mg/L accuracy and IP-67 protection costs more to build than a basic uncalibrated alternative with no waterproofing.

Why Buy Genuine Lutron PDO-519 from astzbd.com

astzbd.com sources authentic Lutron PDO-519 Dissolved Oxygen Meter units with full manufacturer warranty, protecting you from counterfeit or recalibrated meters that fail exactly when a fast, accurate field reading matters most.

Who Needs a Lutron Dissolved Oxygen Meter Like the PDO-519?

Fish Farm & Hatchery Field Staff

Daily oxygen checks across multiple ponds move faster with a pen meter you can dip and read without setting up equipment each time.

Wastewater Plant Spot-Checkers

Quick verification of oxygen levels at various treatment stages benefits from a meter built for repeated, on-the-go use rather than a fixed testing station.

School & College Practical Labs

Students get hands-on experience with a rugged, simple-to-operate instrument that survives regular handling without needing constant recalibration.

Aquarium Retailers & Hobbyist Suppliers

Verifying tank water quality before selling livestock is faster with a compact meter that fits easily behind a retail counter.

How to Use the Lutron PDO-519 – Step-by-Step Field Testing

1. Power on the Lutron PDO-519 Dissolved Oxygen Meter and allow the probe a few moments to stabilize in air
2. Remove the probe cap and immerse the sensor tip fully in the water sample
3. Gently stir or move the probe to eliminate air bubbles trapped against the membrane
4. Wait for the reading to stabilize, then use Data Hold to lock the value if needed
5. Record the dissolved oxygen and temperature reading from the dual display
6. Rinse the probe with clean water and replace the cap after use

PDO-519 Probe & Membrane Care Guide

Keep the polarographic probe membrane free of debris and check it periodically for tears or wear, since a damaged membrane directly affects the accuracy of your Lutron PDO-519 Dissolved Oxygen Meter readings. Store the meter with its protective cap on to prevent the sensor from drying out, replace the spare probe head (OXHD-04) and electrolyte (OXEL-03) according to the manufacturer’s recommended interval, and avoid leaving batteries in the unit during extended storage to prevent corrosion damage.

Lutron PDO-519 FAQ

Is the Lutron PDO-519 waterproof?

The Lutron PDO-519 Dissolved Oxygen Meter carries an IP-65 rating across its full operating range and IP-67 protection up to 30°C, meaning it withstands splashes and brief immersion during field use.

What’s the difference between PDO-519 and DO-5509?

The PDO-519 uses a pen-style, single-hand body designed for quick field spot checks, while the DO-5509 uses a separate probe-and-meter design better suited for setups requiring a longer cable reach into deeper samples.

Can one hand operate the PDO-519 during testing?

Yes, the slim pen-body design of the Lutron PDO-519 Dissolved Oxygen Meter is specifically built for single-hand operation, leaving your other hand free to hold a sample container or take notes.

How is the PDO-519 different from a benchtop DO meter like the DO9100?

The Lutron PDO-519 Dissolved Oxygen Meter is a portable, handheld pen meter for fieldwork and daily spot checks, while the Lutron DO9100 is configured for lab-based testing with extended calibration and measurement options.

How long does the battery last?

The Lutron PDO-519 Dissolved Oxygen Meter runs on four AAA batteries with an auto power-off function that conserves battery life between measurements, giving reliable performance across extended field sessions.
