Dry Gas Meters

Dry Gas Meters

This portable industrial meter has been adapted for experimental use. It is a diaphragm-type, positive displacement Meter that is accurate to ±1.5%. it is ideal for measuring the volume of expired gases collected in Douglas Bags or the volume of gases drawn through a system

The inlet and outlet tubing connections fit the two most frequently selected hose sizes for gas equipment. Hoses with a nominal bore of 22 mm fit directly onto the first step of the connectors. A tapered fitting accepts the 30 mm airway systems with such equipment as Harvard Douglas Bags.

An optically-coupled detector drives a 4-digit LED display in cumulative 0.1 liter increments from 0.1 to 999.9 liters maximum with an electrical zero reset. A 2.5 mm output socket produces a TTL compatible, 5 V pulse with each 0.1 liter increment.

This meter measures, H x W x D, 30 x 20 x 17.5 cm (12 x 8 x 7 in), weighs 4 kg (9 lb) and operates on one 9 V transistor battery (included).
