Masser offers largest range of electronic calipers from where clients can find suitable product covering measuring needs from willow plantations to tropical forests.

Since 1987 when Masser Oy introduced the first one-hand operated electronic caliper, the company has produced data collection systems for forest inventory, pre-harvest measurement, log scaling, pile volume calculation, harvester calibration and control measurements.

Masser-calipers, data collectors, inclinometers, basal area calculators and distance measurement devices are designed easy to use in the tough forest environment. Thanks to their rugged design, these instruments will work for years in the rain, dust, cold, heat and other demanding conditions.

All devices can store the data and results are immediately available for use. Data can be transferred to an operative business system for decision making and reporting
