JRI Mini Disque Chart Recorder

JRI Mini Disque: Remote: Ambient

Reliable, simple and easy to operate, Minidisque are recorders dedicated for measuring temperature and relative humidity. They operate by direct action: the measuring element directly controls the recording device. No energy source is required. Circular chart recording is by continuous plotting with a replaceable fibre tip pen. The window provides visibility for the entire graph. For the remote mode, the temperature is measured by the mean of a probe filled with a neutral gas under high pressure linked to the case by a 3 meters copper capillary.
