A compact and easy to use portable hygrometer which includes an integral sampling system for quick measurement of compressed air or process gas moisture content.
Sulphur hexafluoride is used as an insulating gas in circuit breakers. Excess moisture in SF6 gas causes arcing, which can trip the circuit breaker and cut off power to the distribution network. The amount and rate of damage of the SF6 equipment depends on the concentration of the byproduct formed, which is ultimately based on the quantity of water vapor present in the SF6 Gas. Therefore, the importance of measuring the water vapor content of the gas used within the SF6 filled equipment is to ensure that corrosive electrolytes remain at low concentration level and substantially reduce the risk of damage and cost of maintenance.Simple and Affordable
The STORK DEWRanger-UNO portable hygrometer has been engineered to make moisture measurements in air and process gases on plants or in the field simple and quick. The totally self-contained instrument arrives ready to use.
The DEWRanger-UNO is economical to buy and easy to operate. Automated manufacturing allows us to keep the price low. Operating costs are also low, because the DEWRanger-UNO is reliable and durable. The DEWRanger-UNO utilizes the DEWCom dewpoint transmitter which means that calibration re-certification is achieved by sending just the transmitter to one of our service stations. Even better, by buying - in to our exchange sensor program, the user is assured of interruption free availability of his instrument. Fully Integrated Sampling System
The DEWRanger-UNO incorporates a complete sampling system which allows practical connection to any air or gas line, clean or dirty, at up to 3 MPa pressure.Display
The DEWRanger-UNO portable hygrometer employs a LED 4-digits which in normal mode displays the measured value in large digits as well as battery charge indication.Battery and Charging
The DEWRanger-UNO is fitted with a Lithium-ion battery giving a working time between charges of approximately 16 hours. Charging time from a 100V-240V ac supply or a 12V automobile socket is 2-3 hours.Outputs
The hygrometer is equipped with a 4-20 mA output for connection to a chart recorder.
