THROUGH THE Cultivator's LENS Highlights

  • You are adding root-zone monitoring because checking pots by hand tells you nothing about what is actually happening below the surface.
  • You are switching to this meter because you are tired of damaging delicate probes when pressing them into thick substrate.

  • The 2-metre cable allows you to take readings in containers or beds that are otherwise difficult to reach.

  • Growers who switched to this meter say the dedicated soil probe stopped them from burning through standard glass probes.
  • Operators who regularly check media pH report that the included auger makes getting a clean reading in dense substrate much faster.

Bluelab Combo Meter with Soil pH Probe 

Standard pH probes are built for solution, not soil — pressing one into substrate risks damage and gives you a slow, unreliable reading. The Bluelab Combo Meter with Soil pH Probe solves this by pairing the portable Bluelab Combo Meter with a dedicated Leap pH Probe designed specifically for direct insertion into any growing medium.

A Dibber (Auger) makes inserting the Soil pH Probe fast and damage-free, and the probe stays safely stored and ready to measure the moment you need it. The included Conductivity Probe is calibration-free, so EC readings are accurate from the first use, and Automatic Temperature Compensation keeps every reading correct regardless of substrate or solution temperature.

A 2-metre cable reaches into hard-to-access containers and beds, and a bright backlit display keeps results easy to read wherever you're working. Conductivity scales are fully customizable — EC, CF, PPM 500 (TDS), or PPM 700 — with temperature displayed in °C or °F, so the meter adapts to however your operation already tracks nutrients.

Frequently Asked Questions

How does the Soil pH Probe work with the included Dibber? +

The Dibber (Auger) creates a clean opening in your substrate, letting you insert the Soil pH Probe quickly and without damaging the probe tip.

Does the conductivity probe need calibration? +

No. The included Conductivity Probe is calibration-free and gives accurate EC readings right away.

How long is the probe cable? +

The cable measures 2 metres, giving you enough reach to test hard-to-access containers and beds without moving the meter itself.

Can I change which units the meter displays? +

Yes. Conductivity can be shown in EC, CF, PPM 500 (TDS), or PPM 700, and temperature in °C or °F.

What's the difference between this and the standard Bluelab Combo Meter? +

This version pairs the Combo Meter with a dedicated Soil pH Probe and Dibber for direct substrate testing, rather than the solution-focused pH probe included with the standard Bluelab Combo Meter. For growers requiring moisture data as well, the Bluelab Pulse Meter is a recommended alternative.

Does the meter adjust automatically for temperature? +

Yes. Automatic Temperature Compensation keeps readings accurate as substrate or solution temperature changes.
