CE MDD stands for Medical Device Directive 2014/31/EU and 93/42/EEC as amended by 2007/47/EC. The Medical Devices Directive covers the regulatory requirements of the European Union for Medical Devices. Compliance with the requirements of the Medical Devices Directive is declared by placing the CE Marking on the product, and supplying the device with a Declaration of Conformity. All the CHARDER® scales come with CE marking.

M marking may only be fixed together with the ‘CE’ marking to non-automatic weighing instruments which meet the requirements of the directive 2014/31/EU and 93/42/EEC as amended by 2007/47/EC and which were subject to conformity assessment procedures.

 The (III) marking is based on International Organization of Legal Metrology (OIML) & is identified as Class 3 accuracy. The above mentioned markings are mandatory for EU nations, for other nations these markings are non-mandatory.

NAWI stands for Non-Automatic Weighing Instruments. Weighing instruments used for medical weighing have to comply with the requirements of the NAWI directive 90/384/EEC. The directive is implemented in the UK by the Non-automatic weighing Instruments Regulation 2002.Under these regulations the design of medical weighing instruments must be approved by a notified body,( in the UK this is National Weights and Measures Laboratory) and all products from the production line must be individually verified for conformity and accuracy by a Trading Standards officer or other approved verifier. Each instrument must be covered by a Declaration of Conformity and bear the "" label indicating conformity with the Directive and the Regulations.

It's very important to know how much a subject weigh; not approximately but exactly. The best way to check whether scale need calibration or not, is to use a known weight to see if the scale returns the correct measurement. If the measurement is incorrect, please contact our local service provider for calibrating the scale.

While weighing patients the accuracy matters and if the scale is placed on uneven ground, the chances of wrong weighing results are higher. That’s why all of Charder brand scales have bubble level indicator to check the ground level and adjustable feet to adjust incase the ground is not even.

All CHARDER® scales have bubble level indicator, which indicates whether the scale is on leveled surface or not. If the surface is uneven, please adjust the feet of the scale to match the ground and make sure the scale is not moving after stepping on the platform.
