• Meter Only — Base unit for reliable soil moisture readings.
• Meter + Protective Cap — Adds UV and moisture protection for outdoor use.
• Meter + Protective Cap + Battery — Includes a spare CR2032 3-volt battery.
• Complete Kit (Meter + Cap + Battery + Coring Tool) — Full field kit with the Blumat Coring Tool (1" wide, 11"+ long) for precise sensor installation with minimal soil disturbance.

Insert the probe into your potting mix and get an instant reading in millibar (mbar). The lower the number, the wetter the soil. Use it to dial in your Blumat sensors, check moisture before watering, or track drybacks between feeds.

Purpose-built for container growing — not field soil. Gives consistent, repeatable readings that cheap probes and finger tests can't match.

• The top of the meter is not waterproof — do not submerge or expose to standing water.
• The protective cap should not be seated directly into soil — trapped humidity can damage the sensor.
• Reset instructions available here.
