Products/Services for Jamin Refractometer
-
Refractometers - (149 companies)Refractometers are widely used to measure the amount of dissolved substances in solutions containing mainly sucrose. The relationship between refractive index and the amount of dry substance content is well known for sucrose and is the basis...Measurement ScaleMonitoringMounting -
Interferometers - (105 companies)Interferometers measure distance in terms of wavelength and determine the wavelengths of light sources. -
Battery Monitors and Testers - (193 companies)Battery Monitors and Testers are electronic devices used to test, manage and monitor battery parameters such as voltage, current, charge, temperature, and others.
-
Calibration and Reference Standards - (354 companies)Calibration standards and reference sources include any source that can provide a reference for the calibration of an instrument or comparison of a material or component. -
Refrigerants, Antifreezes, and Cooling Liquids - (207 companies)Primary refrigerants use a thermodynamic or adiabatic process (evaporation-condensation cycles) to remove heat and cool a region. Secondary refrigerants such as antifreeze liquids provide cooling solely through heat transfer. -
Scales and Balances - (945 companies)Scales and balances are used to measure static or dynamic loads for a wide range of industrial applications.
-
Dielectric Greases and Insulating Fluids - (103 companies)...lifespan is determined by the type of fluid used, the type of EDM machining, substrate material, and the EDM fluid filter. A refractometer can determine the quality of used EDM fluid, and overstrained EDM fluids can smell or change color. Specifications...

How to Properly Take a Lab Sample of Your Coolant and Refractometer Readings: Take pH and refractometer readings immediately after collecting the nozzle sample. Document these readings accurately on the QualiChem Laboratory Service Request (LSR) form or any other provided report format. Machine Sump Sample. Circulate: Before taking a sample, allow the coolant to circulate for a few minutes (longer if the machine has not been in use on the day of sampling). Clear the Surface: Most coolant tanks/sumps will have a layer of tramp oils floating... (read more)Browse Metalworking Lubricants, Coolants, and Fluids Datasheets for QualiChem, Inc. -

How to Properly Mix a Coolant and the knob on the proportioner to control the concentration of the mixture. Test coolant with a refractometer. Since the numbers on the dial may not directly correspond to your desired output, it 's important to test the concentration using a refractometer. The Venturi-style mixers are suitable for companies using a few drums per year. The primary drawback is being prone to variations in concentration output based on variations in available water pressure. Method 3: Piston-Style Mixer. The most...

CERAMIC ABSTRACTS
P. suggests that the most accurate information as to the character of the strains in glass wolfld be obtained by the use of a polariscope on the lines of a Jamin refractometer , giving the absolute refractive index parallel to the principal stresses.

A Change of Capacitance Method for the Measurement of Mechanical Displacements
For work in the ultra-violet, the instrument has the advantage over the ordinary Jamin refractometer that only two comparatively thin plates of quartz, silica or fluorite are needed, of only moderate optical quality.

August Toepler — The first who visualized shock waves
In 1870 Toepler, together with Boltzmann, applied Jamin 's interferometric re- fractometer and extended the visualization to very weak sound waves at the threshold of hearing.
