TECHNICAL & Scientific Equipment has released the Keller Leo Record and Leo Record EEx ia, digital instruments that measure both pressure and temperature. They are suitable for use in factories, pipelines, building sites and other locations.
Up to 57,000 readings can be stored in their non-volatile memory and their internal battery has a life of up to five years.
The optional LOGGER 4.X software (for PC and PDA) allow users to set up the Leo Record for the required logging interval and to automatically trigger recording from an event such as a change in pressure. This enables the storage of the data to be reduced and superfluous data to be eliminated. The software also provides a platform for data presentation and analysis. In the field, the logging function is started and stopped using the buttons on the face of the manometer. The buttons also enable the user to zero the reading to any new reference and to select the desired pressure unit (bar, kPa, hPa, m H2O, and psi).
Leo Record is available in ranges from -1 to three bar, to a maximum of 1000 bar. It has a four-digit resolution and a precision of 0.1%FS. It has an operating temperature range of 0°C to 50ºC.
Stored data is output and programming is made via its RS485 interface and an optional interface cable. Leo Record EEx ia is an intrinsically safe version (ATEX convention). Options include a carry bag and a protective rubber jacket.
