Hand-helds from WIKA are portable test and calibration instruments for mobile use. Thanks to the numerous external and exchangeable pressure sensors, many measuring tasks can be solved with a single hand-held. The external pressure sensors can, depending on the model, cover a measuring range of up to 10,000 bar. The measurement accuracy is down to 0.025 % of span and also depends upon the instrument model and pressure range. The external pressure sensors are individually matched to the different hand-held models in accordance with your order and directly from the factory. In addition to your individual hand-held solution, our online shop also offers reference sensors for your existing calibration system – appropriate, inexpensive & on short delivery directly from the manufacturer.
