How often should I calibrate Bluelab pH EC Temperature Meter Bluetooth?

pH meters should be calibrated before every use or at minimum every 2–3 days during active grows. EC meters are more stable but should be verified against a known reference solution weekly. Bluelab pH EC Temperature Meter Bluetooth uses two-point calibration for pH (4.0 and 7.0 buffer solutions) and single-point calibration for EC (2.77 mS/cm standard). Regular calibration is the single most important factor in measurement accuracy.

How do I store Bluelab pH EC Temperature Meter Bluetooth properly?

Always store pH probes wet — never allow the probe tip to dry out as this permanently damages the glass membrane. Use the probe storage solution supplied with Bluelab pH EC Temperature Meter Bluetooth or Bluelab KCl storage solution. EC probes are more robust but should also be rinsed with clean water after each use. Store Bluelab pH EC Temperature Meter Bluetooth at room temperature away from direct sunlight.

What should I do if Bluelab pH EC Temperature Meter Bluetooth is reading incorrectly?

First, recalibrate using fresh buffer solutions — old or contaminated calibration fluid is the most common cause of inaccurate readings. Rinse the probe thoroughly with deionised or distilled water between calibrations. If readings are still inconsistent after recalibration, check the probe for physical damage or contamination. Most probes have a service life of 12–18 months with proper care.

Is Bluelab pH EC Temperature Meter Bluetooth waterproof?

Check the IP rating listed in the product specifications. Most handheld meters are splash-proof but not designed for submersion. Take care when measuring in deep reservoirs to avoid dropping the unit. Bluelab pH EC Temperature Meter Bluetooth is designed for hydroponic nutrient solution testing — it is not rated for outdoor or continuous immersion use.

Does Bluelab pH EC Temperature Meter Bluetooth ship fast within Australia?

Yes — Bluelab pH EC Temperature Meter Bluetooth ships from our Australian warehouse with fast tracked delivery Australia-wide. Most east coast orders arrive within 2–5 business days. WA, NT, and TAS orders typically arrive within 5–12 business days.

Quick Answer

Reads pH, EC and temperature from one probe insertion, at 0.01 pH resolution.
IP68 rated, so it's fully submersible rather than splash resistant.
Replaceable double-junction pH probe and titanium EC electrodes, with a probe health indicator built in.
Ships free from within Australia to VIC, NSW, QLD, SA and ACT.

Bluelab pH, EC & Temperature Meter. 3-in-1 Bluetooth Hydroponic Tester

This meter reads pH, EC and temperature together from a single probe, which is the practical difference between it and carrying two pens. One insertion, all three numbers, and pH shown to 0.01 rather than the 0.1 most handheld pens give you.

It connects to the Edenic app over Bluetooth, so readings log as you take them and you can look at a trend instead of remembering last week's number. The app also handles firmware updates.

The pH probe is replaceable and double-junction, and the EC electrodes are titanium. Between them that's what makes this a meter you keep rather than replace, since the pH probe is the part that wears out and it comes off.

Key Benefits

Three parameters, one insertion. pH, EC and temperature captured together, so nothing is measured at a different moment or a different depth.
0.01 pH resolution. Ten times finer than a typical 0.1 pen, which matters when you're tracking drift rather than just checking you're in range.
Bluetooth logging through Edenic. Live readings to your phone, stored history, and firmware updates over the air.
Replaceable double-junction pH probe. Resists the reference contamination that ends single-junction probes early, and swaps out when it's spent.
Titanium EC electrodes. Corrosion resistant, which is what keeps conductivity readings honest over years in nutrient solution.
Probe health indicator. Tells you when the pH probe needs cleaning, calibrating or replacing, rather than leaving you to work it out from bad readings.
IP68 waterproof. Fully submersible, so dropping it in the reservoir is a retrieval job.

How It Works

Put the probe into your solution. Straight into the reservoir, nutrient mix or a sample.
All three read at once. pH, EC and temperature captured in the same measurement.
Values show on the backlit screen. Readable in the room without the app open.
Bluetooth sends readings to Edenic. Logged automatically for history and trend tracking.
Calibrate against pH 4.0 and 7.0. Two-point pH calibration. The conductivity side needs no calibration.

System Features

Simultaneous pH and EC display. Both on screen together rather than toggling between modes.
0.01 pH resolution. Fine enough to see drift developing before it becomes a correction.
Probe health indicator. Built-in maintenance prompt for cleaning, calibration and replacement.
Two-point pH calibration. Against 4.0 and 7.0 buffers.
Selectable conductivity units. EC, mS/cm, CF, ppm 500 and ppm 700.
Selectable temperature units. Celsius or Fahrenheit.
IP68 construction. Fully submersible in nutrient solution.
Compact handheld design. Single-handed use across multiple reservoirs.

Ideal For

Recirculating and DWC systems. Where pH and EC both move and you want to see them move together rather than in separate readings.
Growers tracking trends. The logging is the point. A number today tells you less than the same number against the last fortnight.
Anyone tired of carrying two pens. One tool, one calibration routine, one thing to keep hydrated.
Tight pH control. 0.01 resolution suits growers actively managing pH rather than checking it occasionally. Our guide on why pH keeps dropping covers what to do with the data.

Recommended With

pH 4.0 and 7.0 calibration solutions. Needed for two-point calibration before first use and at every calibration after.
KCl storage solution. Keeps the double-junction probe hydrated in storage. A dried-out probe is not recoverable.
Bluelab pH Controller. For automated dosing once you want the reservoir managed rather than measured.

Frequently Asked Questions

How often should I calibrate it?

Before every use during an active grow, or every 2 to 3 days at minimum, using fresh pH 4.0 and 7.0 buffers. The probe health indicator will also prompt you. Old calibration fluid is the most common cause of a confidently wrong reading.

Does the EC side need calibrating?

No. The conductivity measurement doesn't require calibration, so the routine is pH only.

How do I store it?

With the pH probe wet, in KCl storage solution. If the glass membrane dries out it's permanently damaged and no amount of calibration brings it back. Store at room temperature out of direct sunlight.

Is it really submersible?

Yes. It's IP68 rated, which is the highest common ingress rating and covers continuous immersion rather than brief splashes. You can drop it in the reservoir and fish it out.

What does 0.01 pH resolution actually get me?

It shows movement a 0.1 pen rounds away. A drift from 5.94 to 6.04 reads as a change on this meter and as a flat 6.0 on a coarser one. That matters if you're managing pH actively, and matters less if you're spot-checking against a range.

Can I replace the pH probe?

Yes, which is the main reason to buy this over a sealed pen. pH probes are consumable and typically last 12 to 18 months. Here the probe comes off and the meter stays.

Does it qualify for free shipping?

Yes. At $384.95 and 0.7kg it clears the $150 threshold and sits well under the 3kg cap, so it ships free to VIC, NSW, QLD, SA and ACT. WA, NT, Tasmania and remote areas are quoted separately.
