Grant SQ800 data logger used in clinical studies

The Grant SQ800 data logger is being used in medical research to back up and support clinical studies into a variety of areas, such as pain relief.

The aim of the study into pain relief was to investigate the effect of interferential current frequencies upon cutaneous blood flow in humans using laser Doppler flowmetry to define the physiological mechanisms involved. Nerve conductivity, blood flow, skin temperature and constant ambient air temperature are measured and analysed. Each variance from standard levels indicates whether or not pain inducement or relief is working effectively. Any variance in air temperature means that the test has to be scrapped and re-started.

On-going clinical studies in a wide variety of medical criteria is critical and strict control is needed over the measurements taken. The SQ800 monitors all these readings, providing all the data the health professional requires whilst warning of variances of ambient air temperature. This type of instrumentation gives confidence that the data will not be flawed. Without the Squirrel SQ800, it would be virtually impossible to monitor these readings in this way.

The SQ800 data logger will measure inputs from a wide range of sensors. It has 8 universal inputs for thermocouples, voltage, 4 to 20mA, current and thermistors. Weighing only 1kg, it can be battery or mains operated. Up to 2 million readings of secure data can be stored. It can be networked via ethernet to a PC based acquisition system, operate in standalone mode, or set up remotely to download via modem to GSM or other wireless systems.
