Georg Fischer Signet
The Signet 2850 Conductivity/Resistivity Sensor Electronics are available in various configurations for maximum installation flexibility. The universal mount version is for pipe, wall, or tank mounting and enables single or dual (digital versions only) inputs using any standard Signet Conductivity/Resistivity sensor. The threaded j-box version can be used with these same Signet sensors for submersible sensor mounting. It is also available as a combined integral system configuration for in-line mounting and includes a conductivity electrode in a choice of 0.01, 0.1, 1.0, 10.0 or 20.0 cm-1 cell constants. The 2850 is ideal for applications with a conductivity range of 0.055 to 400,000 S or a resistivity range of 18.2 M to 10 k.

TAND220A -
Amperis sl
The measuring instrument type TAND220A complies with the international standard IEC 61620. The instrument is based on the so-called "low-amplitude, low-frequency alternating current square wave method" and allows accurate measurements of conductivity and relative permittivity. Conductivity measurement in the range of 0.01 pS/m to 20,000 pS/m allows the use of this instrument for quality control of high resistivity liquids even at room temperature. The TAND220A works with a low test voltage and also with a low test current so that it does not represent a danger for the operators.

Model FT2 -
Gopal Electronics
Franklin Tester Model FT-2 is designed as per IS:649 & ASTM:717 Standard to measure insulation resistivity of electrical steel sheet. It requires precision & noise free DC regulated power supply and equally distributed pressure on electrode. Franklin Tester FT-2 regulated power supply provides 0.5000V with 0.1% accuracy over load and no load. Most of national and international standard has specified only 0.5%, means FT-2 is equipped with five time better accuracy than required.

ASTM D257 -
National Technical Systems
These test methods cover direct-current procedures for the measurement of dc insulation resistance,volume resistance, and surface resistance. From such measurements and the geometric dimensions of specimen and electrodes, both volume and surface resistivity of electrical insulating materials can be calculated, as well as the corresponding conductances and conductivities. These test methods are not suitable for use in measuring the electrical resistance/conductance of moderately conductive materials. Use Test Method D4496 to evaluate such materials. This standard describes several general alternative methodologies for measuring resistance (or conductance). Specific materials can be tested most appropriately by using standard ASTM test methods applicable to the specific material that define both voltage stress limits and finite electrification times as well as specimen configuration and electrode geometry. These individual specific test methodologies would be better able to define the precision and bias for the determination.

ECOPIA
Classic hall effect measurement system is to read voltage difference made between both diagonal sides, when flowing current and applying magnet field strength, in perpendicular to flowing current direction. - Photonic hall effect measurement is to read various electrical properties by illuminating light of “various range of wavelength” on the sample, in addition to flowing current and applying magnet field strength. - It is great to see “RGB (Red, Green, Blue), Light intensity vs carrier density, carrier mobility, resistivity, hall coefficient”

TP02 -
Hukseflux Thermal Sensors B.V.
TP02 is a probe that offers the possibility to perform a practical and fast measurement of the thermal conductivity (or thermal resistivity) of the medium in which it is inserted at the highest accuracy level. It works in compliance with the ASTM D 5334-00, D 5930-97 and IEEE 442-1981 standards. The standard TP02 probe has proven suitability in soils, thermal backfill materials, sediments, foodstuff, powders, sludges, paints, glues and various other materials. The Non-Steady-State Probe (NSSP) measurement method (also known as transient line source, thermal needle, hot needle, heat pulse- and hot wire technique) has the fundamental advantages that it is fast and absolute while the sample size is not critical. Hukseflux is specialised in NSSP design. Special models have been developed for in-situ field experiments. For permanent installation in soils, a dedicated model, TP01, is available. TP02 has been designed and tested in collaboration with the Applied Physics Group of Wageningen University.
