As Tensitron is the original manufacturer of its products, service and calibrations performed by Tensitron on its tension measurement instrumentation are in compliance with QS-9000 and ISO-9000 standards and requirements. Certification of Tensitron's calibration weights meets the requirements of ISO Guide 17025 and are directly traceable to N.I.S.T.
Per ISO-17025, calibration intervals for our certified weights are to be determined by Tensitron, the user. Upon the advice of the Measurements Standards Division of the State of Colorado Department of Agriculture, we have established this interval at five years from the date of the last inspection. Therefore our next scheduled recertification is to be completed by June 20, 2019.

The State of Colorado has issued a "change in Licensing Period" for Tensitron's scales, changing our due date from June 30, 2014 to December 31, 2014. Click here to view .pdf file of the State of Colorado Change Notice and current Calibration Certificate
Tensitron's instrumentation falls under RoHS Product Category 8 and 9 exclusions.
"Medical devices, and monitoring and control instruments comprise RoHS Category 8 and Category 9 products respectively. The EU recognizes that these products are manufactured in small numbers and generally have a long product life. Further, these products are often used in mission-critical applications where their failure can reasonably be expected to be extremely disruptive, if not catastrophic. Since the long term effects of lead-free solder, a primary RoHS objective, cannot be known for a period of at least five years following the directive's application to the remaining eight categories, the EU has established at least a temporary moratorium of Category 8 and 9 products". 1.

All of Tensitron's handheld digital tension meters use rechargeable NiMH batteries (nickel-metal hydride) and include power supplies which can take input voltages from 100-240V and include several, interchangeable "blades" allowing for use with US, European, Australian, and other plug configurations.
