Product Details:

Measuring the line loop contact resistance by bridges is not the ideal method as the test current is only a few milli amperes. Thus the value is not the true value of the contact resistance. Model VT is a direct reading tester, and uses a test current of 100A DC, resulting in true value and accurate measurements. Model VT’ adopts digital circuit techni-que and is used for measuring contact resistance of switch control equipments at test current of 100A /200A DC. The measurements are accurate as the test is highly stable. ‘NUNES’ VT series is a new, fully automatic micro controlled tester that measures contact resistance at 100A/200A DC with built in printer.

VT-series is micro controller operated user friendly, accurate, reliable, small, light weight and reliable tester. It incorporates a large LCD screen for display of menu and results. The results are printed on built-in printer after the test is over. It incorporates breakthrough technology and design that gives accurate and reliable results, again and again. RS 232 link is also provided.

Product Details:

This instrument is used for determination and checking of bitumen percentage in the bituminous mix. The mix is added with a solvent and dissolved bitumen is removed by centrifugal action. Consists of a removable aluminum rotor bowl. This shaft and thus the bowl is rotated fast manually by enclosed gears in the cast body and handle. A solvent is introduced during the test through the holes in the cap of the housing. A drain is provided to collect dissolved bitumen coming out of the rotating bowl and getting collected in the housing.

Product Details:

Test method :- Aniline point is used to characterize pure hydrocarbons and to indicate the aromatic content of hydrocarbon mixtures. Equal volumes of aniline and sample or sample plus n-heptane are stirred together while being heated at a controlled rate. After the two phases become miscible, the mixture is cooled at a controlled rate and the temperature at which the two phases separate is the aniline point or mixed aniline point of the sample.

Standard :- Conforms to: astm d611; ip 2; iso 2977; din 51775; ftm 791-3601. for aniline point and mixed aniline point determinations according to method b. Stirs aniline-sample mixture in a borosilcate glass thin film tube suspended in a heating bath. Thin film of mixture flows over a light well illuminated by a variable 6v lamp. Adjust heating rate per specifications using accessory powertrol heater. When lamp filament brightens inside well, allow mixture to cool until the two phases separate as indicated by obscuring of the lamp filament. Consists of thin film tube; 400ml pyrex™ beaker; cover assembly with bath stirrer, sample pump rotor and cooling coil; 6v lamp with line cord; and drive motor. Positive drive pulley system rotates sample and bath stirrers. Accessory powertrol heater has variable stepless control and a reference dial for repeatable control of heating rate. Porcelain refractory top plate shields 75ow heater and has a positioning well for the borosilicate bath. Low voltage receptacle in heater housing accepts line cord of 6v lamp.

Product Details:

Carbon dioxide and temperature transmitters are wall-mount transmitters designed to fulfill the needs for CO2 measurements in standard demand controlled ventilation (DCV) and Indoor air quality monitoring (IAQ). The CO2 measurement is based on a second generation sensor, which uses a novel, silicon-based microchip emitter. The internal reference in the CO2 sensor guarantees the best stability and operation also in constantly occupied buildings without frequent readjustments.

 

The sensors give correct CO2 measurements immediately when powered on. Proper operation can be verified immediately after snapping on the device cover.

 

The VT-V86P includes a Pt1000 RTD Class F 0.15 IEC 60751 (Class A) that can be wired to a controller for temperature measurement.
