| For determination of resistance of aggregates to wear by abrasion. It consists of two hollow cylinders closed at one end and provided with tight fitting covers at the either end. These cylinders are mounted on a shaft at an angle of 30 degrees with the axis of rotation of the shaft. The shaft rotates at 30-33 r.p.m. through a reduction gear operated by a motor and is provided with a revolution counter. Complete with abrassive charges consisting of 12 Nos. Hardened steel ball of 48mm dia. Suitable for operation on 440 volts, 3 phases, 50 cycles. A.C.supply. |
| HV Spark Tester is designed for checking the quality of pvc coated or insulated wire online manufacturing unit. The insulated wire is passed through brass ball chains which are carrying high voltage. If any pinhole or fault comes in insulated wire, the spark develops and electromagnet counter counts the fault. The spark tester is therefore necessary for every cable manufacturing unit. Our spark testers upto 15 KV are air cooled (there after for higher capacity transformer is oil cooled and control panel air cooled). |
This is a compact, portable self-contained Instrument which is used for direct reading of insulation resistance of electrical installations and apparatus. The Insulation tester is composed of a hand driven A.C. generator and a high sensitivity cross-coil Indicator. The indicating movement is of the cross coil ratio type and is designed so that voltage fluctuation, caused by irregular cranking have no influence on the results of measurement. The AC Magnet hand generator drive is extremely smooth and silent. There are no carbon brushes and commutators, to be replaced as in DC generators. The quick response saves the time and extend the life of the generator. Available in various ranges from 10 to 500 Mega Ohms.
| Insulation Tester (Meggers) Transistorised |
These have been designed with a view of stronger and rugged construction of individual components, which have been tested by us for last so many years, and thus ensuring longer life of the instrument. The size and weight of this model has been considerably reduced with a view of making the instrument more handy. The indicating Instrument is specially protected seperately in a moulded case to prevent damages from dust at the time of servicing. The indicating instrument has knife edge pointer and Anti-parallax mirror scale for ensuring accurate readings. Single person operation push button control, no troublesome cranks to turn, usage of standard 1.5 volts pencil cells are all the special features.
ACCURACY : (+/-)5% of indicated value.
WORKING PRINCIPLE : A push pull oscillator is used to convert DC voltage to AC, which is stepped up and further rectified to give the test voltage which is DC. A sensitive movement is used to detect the change in current due to insertion of resistance in the circuit. Available in various ranges from 10 to 500 Mega Ohms.
| A fairly handy instrument for taking quick readings for the hardness of tablets. It is made of brass turned parts. Heavily chrome plated the scale is 0 to 20KG. The index mark and division is in reading . Scale is adjustable for zero setting as per size of the tablets. |
| For determining Light fastness of Textiles against MBTL fading Lamp. Provided with 4 Nos. sample holder, hour meter with buzzer, cooling arrangement with pump & water tank. |
High voltage breakdown tester are useful for measurement of breakdown (flashover) voltage of electrical components, insulation materials instruments, transformers, etc. can be used to ascertain quality of insulation material before planning their usage in electrical applications. The front panel incorporates all controls for operation of the unit. Easy to use test probes with micro-switch supplied to connect the output high voltage to the device under test.

Used for determining aggregate impact value. It consists of a circular base with two vertical guides. The hammer of weight 13.75 0.25 Kg can be raised to fall freely down the vertical guides. The height of fall can be adjusted through 380 5mm. The hammer is provided with a locking arrangement. The hammer falls freely to the base and is removable for emptying. Supplied complete with metal measures 75mm dia x 50mm height (for specimen preparation) and tamping rod 230mm long x 10mm dia.
| Also available with automatic blow counter. |
