With calibrated flow ranges are 1 to 50µL, 30 to 1000µL, and 0.2 to 4.0 mL, this line of TruFlo sample flow meters to include 6 separate configurations. Each configuration is available in standard or HF resistant models. They measures and displays the sample flow rate to an ICP-OES or ICP-MS nebulizer. Sample flow-rate discrepancies are indicative of problems such as a clogged nebulizer, faulty peristaltic pump tubing or improper pump tension. They can be programmed to sound an alarm when deviation from specified flow rates occurs and also produce an electronic record of sample flow rate over a 24 hour period for regulatory compliance.
