Precision Laboratory Heat Sealer - for accurate and repeatable determination of heat seal threshold. Produces seals 5 to 25mm wide and up to 650mm long.  Precise control of heat sealing process variables (temperature, pressure, and dwell time), enables an optimal balance of material specification, packaging machine speed and seal integrity. Accuracy and repeatability in laboratory heat seal testing is vital, and the HS-650 provides precision digital controls for this purpose in this special version for seals up to 650 mm wide. Produces seal 5 – 25 mm wide and up to 650 mm long.
