		Model 100 flow controller Fixed span upstream-referenced flow controller The Model 100 is available in a variety of preset maximum flow rates, from 150 mL/min to 10 liters/min (N2 at 40 psi). Any flow controller in this series can be equipped with a 10-turn Spectrol digital dial (3 or 4 digits), to permit a visual indication of the flow setting. The Model 100 comes with 1/8" external tube fittings (EAOR22). Other fittings are available. All flow rates listed in the product number tables are based on N2 at 40 psi inlet pressure. Maximum inlet pressure is 200 psi. Request Quote

		Model 202 flow controller Adjustable span upstream-referenced flow controller The Model 202 provides a user-variable span adjustment permitting it to be used for a variety of flow ranges. The flow range is infinitely adjustable from a minimum flow as small as 0.5 mL/min up to a maximum flow of 1.6 L/min (N2 at 40 psi). After the span is adjusted, the flow controller has a full 10 turns of resolution between zero flow and the maximum rate. When equipped with a Spectrol digital dial, settings are reproducible to better than 1%. The Model 202 comes standard with 1/8" NPT female pipe threads. Adapters to go from pipe to 1/16" OD tubing are included. Other fittings are available. All flow rates listed in the product number tables are based on N2 at 40 psi inlet pressure. Maximum inlet pressure is 200 psi. Request Quote

		Model 300 flow controller Fixed span downstream-referenced flow controller The Model 300 flow controller provides a stable flow rate when upstream pressure conditions vary, providing the downstream pressure remains constant. The maximum flow rate available is 1.6 L/min with ambient downstream pressure. Available with standard knob, Spectrol 3- or 4-wheel 10-turn digital dial, or with screwdriver adjustable stem. The Model 300 comes standard with 1/8" external tube fittings (EAOR22). Other fittings are available. All flow rates listed in the product number tables are based on N2 at 40 psi inlet pressure. Maximum inlet pressure is 200 psi. Request Quote
