The Cole-Parmer Ultralow Liquid Differential Pressure Flowmeter, 4-30 mL/min is compact and fully contained unit provides flow measurements via differential pressure in ranges from 0 to 25 mL/min. The simple four-button control panel allows you to show flow/total, units of measure, zero, and power the unit on or off. Easy-to-read 7-digit LCD displays the current and total accumulated flow. Accuracy is ±2% full-scale for liquids with temperatures of 68 to 86°F (20 to 30°C). Below and above these temperature ranges, the accuracy is ±4% full-scale, and unit may be used with fluid temperatures from 32 to 122°F (0 to 50°C). You can adjust a viscosity compensation correction for more accurate measurement. Unit is constructed with chemical-resistant ABS plastic.
