The Truweigh Marine is a sleek digital mini-scale capable of finely tuned measurements of up to 100 grams, or just over 3.5 ounces.
True to its name, the Truweigh Marine is an IP65-rated scale, meaning it is certified dust-proof and resistant to water scrubs and/or sprays, so the scale is easy to wash down after particularly heavy (or sticky) use. We noted warnings, however, that while it is water-resistant, the Marine is not water-proof and should not be submerged. It is rated for measurements with 0.01 readability.
The scale includes a plastic cover that efficiently doubles as a holding tray so things won’t fall off the scale as you weigh them. Batteries come included, along with a miniature Phillips head screwdriver — necessary for opening the snugly fitted battery compartment. In fact, if we had to name one gripe with this scale, it would be that the tiny screws holding down the battery compartment’s lid can be difficult to unscrew, but that’s the price you pay for a super tight, dust-proof casing.
Remember: the Truweigh Marine is a wipe-down capable scale which simplifies cleaning and helps avoid contamination between weighing sessions.
It is possible to swap through units of measurements via the digital interface; your options include grams, ounces, troy ounces, pennyweights, carats, and grains, meaning you can put this scale to work in the grow house, kitchen, or even workshop. The Marine can also be programmed for more complicated measurements, including a Counting Mode, and can be recalibrated if the need ever arises, although it is recommended you carefully consult the included user guide first as the calibration process is permanent.
The Truweigh Marine comes calibrated from the manufacturer for highly responsive measurements, so much so that we noticed even a breath of air or minor vibration can distort the readings. Therefore, users should be extra mindful about not using the scale in any amount of wind, or on an uneven/vibrating surface.
With a price tag of $39.99 and a three-year limited warranty, Truweigh’s miniature design makes for an excellent option for home growers, as it is efficient at measuring smaller quantities of flower and/or concentrate, or even tinctures and topicals.
