The Titrette ® bottle-top burette has an innovative new measuring system, so even the error limits of Class A glass burettes per DIN EN ISO 385 are met. If needed it can display 3 decimal places for volumes below 20 ml. • Precise titration within the error limits of Class A for glass burettes. • The operating elements of the bottle top burette Titrette ® are clearly structured. • Separate buttons for On/Off, Pause, and CLEAR for cancelling the display, as well as for selecting the function. • High stability due to compact design and light weight. • Slip-proof hand wheels and smooth precision gearing for all titration speeds from rapid to drop-by-drop make handling the device particularly safe and easy. • Easy to dismantle for cleaning, maintenance and part replacement in the lab. • Additional electronic functions: Adjustment with Easy Calibration, Calibration schedule to save a date for the next calibration, Save power with Auto-Power-Off, Change decimal place settings. • PC interface (optional) for a data transmission directly to the PC. • Titrette ® SH to determinate the acid content of milk and liquid dairy according to Sox- hlet-Henkel (4 °SH = 1 ml).
