Benetech GM605 vs GM610 vs GM620 Wood Moisture Meter Buying Guide Malaysia
Choose by Material, Probe Design and Inspection Needs
The Benetech GM605, GM610 and GM620 provide different combinations of material settings, probe design and environmental measurements.
The GM605 offers four wood settings plus four additional material settings. The GM610 adds temperature and relative humidity measurements while using short pins. The GM620 provides similar measurement functions to the GM610 with a separate long-pin probe.
For timber suppliers, furniture workshops and renovation contractors in Malaysia, the best choice depends on the material being checked and how the probe needs to reach the measurement location.

The measurement range depends on the selected wood setting. Confirm the applicable species group from the operating manual before interpreting readings.
Choose GM605 for Wood and Additional Material Settings
The GM605 moisture meter is worth considering when inspections involve wood and other materials supported by its selectable scales.
Its four additional material ranges are listed as:
Material A: 0–6.8%.
Material B: 0–6.6%.
Material C: 0–6.0%.
Material D: 0–12.2%.
The supplied catalogue page does not identify the materials assigned to A, B, C and D. Confirm those mappings before purchasing it for a specific building material.
The GM605 also provides maximum and minimum moisture recall, which can help users review variation during a checking session. Its integrated short pins suit local measurements where small puncture marks are acceptable.
Choose GM610 for Moisture and Environmental Checks
The GM610 combines wood moisture measurement with temperature and relative humidity readings.
For workshops and storage areas in Selangor and Kuala Lumpur, these additional readings can help document the conditions around timber at the time of inspection.
However, air humidity and wood moisture are different measurements. An acceptable room humidity reading does not establish that a timber piece meets its required moisture limit.
The GM610 also offers backlight control, data hold and maximum moisture recall. Its listed 9.8 mm pins make it suitable to consider when short-pin access meets the inspection requirement.
Choose GM620 When the Long-Pin Probe Is Needed
The GM620 shares the GM610’s listed wood ranges, temperature range and relative humidity range, but its illustrated configuration includes a separate long-pin probe with a listed length of 147 mm.
This probe arrangement may be useful when an integrated short-pin instrument cannot conveniently reach the intended measurement location.
Before ordering, confirm the probe configuration, connection and insertion procedure for the material.
A 147 mm probe length does not establish a verified 147 mm detection depth. The catalogue does not specify detection depth, so do not assume the reading isolates moisture at the probe tips or represents the centre of a thick timber section.
A Wider Range Does Not Mean Better Accuracy
The GM610 and GM620 list higher upper limits than the GM605 on their wood scales. This helps define measurement coverage, but it does not establish greater accuracy.
The supplied page does not state moisture measurement accuracy or resolution for these three models. If the application involves a narrow acceptance limit, confirm those specifications before choosing an instrument.
Also, avoid comparing percentages taken with different species settings as though they use the same scale.
Check Computer Connectivity Before Buying
The catalogue marks “Use a microcomputer” for the GM610 and GM620, but it does not explain the interface, software or data-transfer method.
If computer use matters to your workflow, confirm the exact capability and supplied accessories. Do not assume USB export, continuous logging or report generation from this entry alone.
Take Consistent Readings Across the Batch
For timber users in Johor and Penang, useful inspection records should include the material, selected group, measurement location and reading.
Check several locations and multiple pieces using a consistent procedure. Compare results against the applicable timber supplier, flooring manufacturer or project requirement.
One reading should not automatically approve an entire delivery. Where results are inconsistent or close to the acceptance limit, further verification may be needed.
