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
| Feature | Lutron PDO-519 | Lutron DO9100 |
|---|---|---|
| Form Factor | Pen-style, single-hand handheld | Benchtop/lab-configured instrument |
| Target User | Field technicians, daily spot checks | Labs needing extended precision testing |
| Measurement Complexity | Straightforward DO + temp readout | Broader parameter and calibration options |
| Portability | Fits in a pocket or field bag | Designed for a fixed lab or research setting |
| Price | ৳21,000 | Contact astzbd.com for current pricing |
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
- Power on the Lutron PDO-519 Dissolved Oxygen Meter and allow the probe a few moments to stabilize in air
- Remove the probe cap and immerse the sensor tip fully in the water sample
- Gently stir or move the probe to eliminate air bubbles trapped against the membrane
- Wait for the reading to stabilize, then use Data Hold to lock the value if needed
- Record the dissolved oxygen and temperature reading from the dual display
- 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.
