Gauss Meters
A gauss meter displays electromagnetic wave measurements in Gauss (G), milliGauss (mG), milliTesla (mT) or microTesla (µT) units. A gauss meter can detect either static (DC) permanent (rare-earth) magnetic or dynamic (AC) electromagnetic fields (EMFs), or both. Thus, it is important to review the specifications of a gauss meter prior to purchase to ensure suitability for the intended application.Neodymium (NdFeB) permanent magnets are among the world's strongest and most widely used magnets. When testing magnets made of neodymium or other rare-earth elements, a gaussmeter or magnetometer capable of measuring DC magnetic fields is required. However, most electromagnetic fields encountered are generated by AC currents. Examples include electrical power lines, transformers and wiring for overhead lighting, solar panels and other electrical devices and equipment. Electromagnetic fields from electrical installations are believed to cause feelings of nervousness, anxiety and paranoia in EMF-sensitive human beings.Most gaussmeters offered by PCE Instruments can be calibrated and certified according to DIN ISO 9000 standards for an additional fee. Replacement gaussmeter probes and optional accessories are available for most gaussmeter models.

Motor Starting & Control Resistors
Motor Starting Resistors are used to reduce the voltage at the motor terminals and also decrease the starting current. Motor Starting Resistors are necessary because the self resistance of a motor armature is very low. When the voltage is first applied, excessive current will flow. For limiting this current, since there will be no resisting back electromotive force (emf),some series resistance can be added to the armature windings.

Precision Thermometer
F252
ASL's F252 provides high accuracy, dual channel temperature measurement with Platinum Resistance Thermometers - PRTs - and uses AC bridge technology as developed by ASL for Standards Laboratories throughout the world. Model F252 requires no regular recalibration, the AC circuit techniques eliminating thermal EMFs and drift, while providing excellent long term stability. Front panel data entry allows you to enter probe calibration data into the F252's memory, so that thermometer resistance can be accurately converted to temperature in C, F or K. This can be password protected to prohibit unauthorised or accidental data entry.

EMF Detector
ElectroSensor™
This EMF detector is an unparalleled value that offers fast, reliable, and user-friendly measurements of electromagnetic pollution. Since man-made alternating current (AC) is different from naturally occurring EMF, some sources say that even extended exposure of as low as 2 milliGauss may be harmful. Fortunately, once EMF sources are identified with your ElectroSensor you can moderate your distance and exposure.
