Sturdy, compact, self contained bench top unit for determining the surface strains and deflections of a flexible diaphragm under varying pressures. Round Diaphragm Apparatus the diaphragm is flexed, the strain gauge output is fed into a digital display, which is supplied. An aluminium diaphragm is clamped rigidly around its outer edge, creating a volume underneath its surface into which oil is filled. On the top surface of the diaphragm are attached 8 precision strain gauges at differing orientations.
An analogue pressure indicator monitors the pressure, whilst an electronic pressure sensor monitors the same pressure but gives an output signal to the digital display. The force applied to the diaphragm is created by pressurising the oil underneath the diaphragm using a fine adjustment control mechanism.
Experimental Capabilities:
Measurement of diaphragm disc surface strain using strain gauges
Determination of circumferential strain
Diaphragm surface profile
Measurement of diaphragm disc deflection with a dial gauge
Determination of radial strain
Comparison of actual and theoretical results

The NT Temperature Data Logger is a multi-use, User-programmable Temperature Data Logger (UTDL) with an USB interface for data download, analysis, and programming of device settings via a PC or Mac. The device shows the most recent temperature measurement and any temperature alarms that have occurred via an LCD screen.
Device settings, such as alarm thresholds, logging interval etc., can be programmed by the user via the free b.plus software or factory programmed. The device is supplied unprogrammed by default and if factory-programmed settings is required, device settings need to be specified upon ordering.
When connected to a PC or Mac via the USB interface, the device generates a report via the free b.plus software. Data can be exported from the software in PDF and CSV file formats.

Oxygen concentrators are not suitable to be used as an oxygen source to other medical equipment providing respiratory support, such as ventilators, CPAP devices, High Flow Nasal Oxygen, etc.
Ventilator, Intensive Care, for adult, paediatric and neonatal patients, AC and battery powered, with accessories.
Mechanical ventilators are life support devices that move gas (e.g., air and/or oxygen) to and from a patient's lungs. In most cases, mechanical ventilators are used for a short period of time (a few days to a few weeks) to deliver pressurized medical gases to the patient's lungs to support gas exchange and rest ventilatory muscles until the patient is able to breathe without mechanical assistance. Some patients, however, require permanent ventilatory support. These devices may provide temporary or permanent respiration for patients who cannot breathe on their own, or who require assistance maintaining adequate ventilation because of illness, trauma, congenital defects, or the effects of drugs (e.g., anaesthetics).
