Short answer: A timber floor moisture meter can help you record moisture readings before oiling, but it cannot decide the finish date by itself. The listed Scannertester product is sourced against the Extech MO50 configuration. Extech publishes a pin range of 5 to 50% for wood, a maximum resolution of 0.10% and replaceable 8 mm contact pins. Extech does not publish a universal moisture limit for every timber floor or hardwax oil. Compare readings with the flooring and oil manufacturer instructions, use the same documented method at several representative points, and treat accuracy, calibration status and final coating suitability as unresolved unless the relevant manufacturer specifies them.

What the listed meter can measure

The product page identifies a pin moisture meter sourced against the locked MO50 configuration. Extech lists wood readings from 5 to 50%, other building materials from 1.5 to 33%, and a maximum pin resolution of 0.10%. Those are the documented display boundaries and resolution, not a promise that every timber floor or species will produce a decision-ready result.

The MO50 uses replaceable threaded contact pins listed at 8 mm. That makes the measurement a contact reading at the points reached by the pins. The product manufacturer does not specify the accuracy for this listing, the calibration status of the supplied unit, or a floor-specific correction for species, temperature, finish or construction.

A repeatable floor check

Use a written comparison rather than one attractive number on a single board. Record the board area, the reading, the date and the product instructions that will govern the finish. If a reading is outside the published wood range, the instrument cannot be treated as a reliable guide for that result from the cited facts alone.

Before buying, check whether the pin format suits the locations you can access without damaging a visible surface. The product page does not specify a non-marking method, exact measuring depth for floorboards or a procedure for coated timber. Ask the relevant manufacturer when those details affect the job.

  1. Identify the exact timber, floor construction and finish product, then collect their current manufacturer instructions.
  2. Choose several representative boards and record readings in a consistent pattern instead of relying on one isolated point.
  3. Compare the readings with the finish manufacturer's stated preparation requirements; do not invent a pass or fail threshold.
  4. Keep the meter result as a moisture indication and obtain professional advice if the floor, substrate or finish remains uncertain.

Why a reading is not an oiling clearance

A moisture reading describes the instrument response at the tested contact points. It does not diagnose the source of moisture, prove that the substrate is dry throughout, or guarantee adhesion, curing or appearance after oiling. The product manufacturer does not specify a universal floorboard moisture value for every oil, timber species or installation.

For that reason, the finish manufacturer's preparation instructions take priority over a generic search result. If the oil maker gives no value for your exact floor, record that gap as manufacturer does not specify rather than converting the meter's range or resolution into a made-up recommendation.

Limits and safe checks before buying

HSE says refurbishment work must be planned so people are not exposed to electrical risk, and specialist electrical work should be done by trained and competent people. A pin meter is not a detector for hidden cables, pipes or structural defects. Do not push pins into an area where the floor construction or services are unknown; isolate the work area and use the appropriate competent trade when the risk is not clear.

The cited product facts do not specify ingress protection, impact resistance, service life, measurement accuracy or suitability for a particular coating system. They also do not guarantee that a reading will predict finishing success. Buy only if the documented MO50 configuration and the unanswered questions fit your process.

Choose the listed meter for documented point readings, then let the timber and finish manufacturers decide the preparation requirements; do not treat the instrument as a guarantee of a dry, safe or finish-ready floor.
