CONTROLLED PURGE SYSTEM FOR GLOVE BOXES

General description

Maintains a slight positive pressure in any Plas-Labs glove box. This self regulating purge system controls nitrogen (inert) gas consumption by regulating flow rate. An integral humidity sensor continually monitors interal humidity levels. If the humidity inside the chamber falls below the adjustable setpoint, the controller switches to high gas flow. Once the desired humidity has been restored the controller resumes low gas flow. Basic features include: programmable logic controller, humidity sensor, black material housing, two manually adjustable high and low gas flow knobs, audible alarm, timer, solenoid valve, stainless steel compression fittings for gas line hook-up.Humidity range: 0-100¬curacy: 0.5% for full scaleSetpoint accuracy: 0.1% for full scaleGas connection: 3.1 mm NPT (1/8 in. NPT)Gas inlet pressure: 4 psi
