Description
Height measuring device for angle of repose determination enables precise digital reading of cone height in bulk-angle tests. The instrument features an extended measuring needle and a clear digital display, giving a resolution of 0,01 mm (0,001 inch) and a repeatability of 0,01 mm. Maximum measuring speed is 1 m/s. Housed in a robust metal casing, the device is intended for laboratory use with angle-of-repose apparatus such as the Dr. Pfrengle setup according to DIN ISO 4324. Working temperature range is 5–40 °C; maximum humidity is below 80 %. Net weight is 2,3 kg. Supplied as one piece from manufacturer Landgraf HLL, it supports accurate, reproducible height readings that convert directly into reliable angle-of-repose values for powders and granules. An optional calibration certificate is available for the related article L50566070H1 when documented traceability is required. The combination of extended needle, fine resolution and digital readout makes routine cone-height measurement straightforward in quality-control and materials-characterisation laboratories.
This article is part of Hygrometers & humidity meters, in Temperature measurement.

Questions about Height measuring device for angle of repose determination
What is this article?
Height measuring device for angle of repose determination is the article on this page. Luminix Health distributes Landgraf HLL for laboratory use. It sits in Hygrometers & humidity meters, inside Temperature measurement, in Instruments de laboratoire.
A hygrometer measures the water in the air, as relative humidity or as dew point. It is the instrument for a desiccator room, a stability chamber or a store. The sensor drifts, and the calibration is part of believing the number.
A thermometer reports a temperature. A liquid-in-glass thermometer is a calibrated column. A digital thermometer is a sensor and a display, and the sensor, not the display, is what is calibrated. An infrared thermometer reads a surface and depends on emissivity. A data logger stores the reading over time. Without a stated uncertainty and a calibration point, the number is only an indication. The scale is maintained by the BIPM and compared by EURAMET. Accreditation is BELAC.
Which category should I open next?
The category is Temperature measurement. The sub-category is Hygrometers & humidity meters. The catalogue is Instruments de laboratoire.
Shelves beside this one are Laboratory glass thermometers, Temperature probes & sensors, Data loggers, Temperature measurement accessories, Digital thermometers and Infrared thermometers.
