HT323 Flowmeter: A dual channel flowmeter for measuring and documenting blood flow during surgery. Features   Large Visible Display of mean volume flow (ml/min) FlowSound®: an audible indication of volume flow . Invert: indicates direction of flow Signal Quality Indicator: tells quality of ultrasonic contact Chart Recorder documents phasic patterns; mean, minimum, and peak flow readings, PI (single button operation, auto scaling) Easy Operation: one button operation, auto-scaling, automatic readout, one-button printing   Compatible Flowprobes HQ-Series Flowprobes for Real-time, quantitative measurements of blood flow. Perivascular flowprobes: non-constrictive, simple application to exposed vessels Precalibrated Probes - report pulsatile, directional flow in ml/min Tubing Flowsensors - report flow in bypass tubing Safe, Low Power Transonic Ultrasound   Micro-Flowprobes - used to compare baseline and post-clip flows during aneurysm surgery. Designed for deep intracranial surgery. Their bayonet handle permits use under a surgical microscope . A flexible neck segment permits bending the flowprobe as needed for any vessel orientation. Disposable (to prohibit spread of Creutzfeld-Jakobs Disease [CJD])   Compatible Flowsensors Transonic XL Sensors Ultrasonic transit-time sensors, specifically designed for tubing, measure volume flow with highest accuracy. Most non-aerated liquids can be measured including saline and buffer solutions, blood, water and even diesel fuel. No physical contact is made with the fluid media. XL-Series Flowsensors can be calibrated and programmed for up to 4 different fluid / temperature / tubing combinations and will work with most flexible tubing types. Sensor size is determined by outside diameter of the tubing.   Support   Manuals: Dutch English French German Italian Spanish Service Manual   Specifications   HT313/HT323(-CS): HT313: Single channel flowmeter with built-in chart recorder; HT323: Dual-channel flowmeter with built-in chart recorder; HT313, 10 lb (4.5 Kg), HT323: 11 lbs (5 Kg) 11"(27.8 cm) wide x 4" (9.1 cm) high x 14" (35.4 cm) deep; attached two-meter flowprobe-to-flowmeter extension cable per channel; separate grounded medical grade power line-cord.
