Resistance Box Plug Type: Superior quality Heavy Brass metal blocks size 1/2" are bound to bakelite plate by means of nuts and screws securing rigid fixation and eliminating any chance of contact error creping due to loosening of plugs and lugs which are cut to fine taper and are interchangeable. Plug heads are machine moulded, of heavy insulated bakelite in beautiful shapes. The boxes are made of Teak-wood and nicely polished.

Great care is taken in preparing the wire wound resistance. Selected double Covered Eureka Wire is wound in bakelite spools. Sufficient ageing and Heat Treatment is processed through to avoid any moisture effects. Solder Joints are sealed after calibration. All Resistors are calibrated on imported Testing Bridge Accuracy ± 0.1%.

Similar to but slotted masses as one of mass 10kg, one 5kg, Two 2 kg, one 1kg. and three of mass 0.5 kg. each making total load of 22.5 kg. Carrier hanger 1kg.

It comprises of two cast iron uprights vertical pillars height approx 180 mm linked by rods, supporting an expansion bar, length 380 mm, fixed to one upright and resting on a friction pointer at the other with scale, supplied with one each aluminium; iron and brass expansion bars.

Made from optically worked glass, highly polished

This is a hand driven generator mounted on wooden base. Consist of two Aluminium spheres of dia 150 mm and 75 mm for charge collecting and discharging purpose, respectively. Both the spheres are removable. The discharge sphere is supported on pivoted arm. The large sphere surrounds the upper part of the charge generating belt assembly and charge accumulates on the sphere, when the hand wheel pulley is rotated. The charge generating belt is mounted on a insulated vertical pillar provided with metal brushes. A 4 mm socket is provided at the top of large sphere.

Fine cut, comprising one each: 12mm wide flat (thin with slight taper), 12mm wide pillar (Straight Flat) with safe edge, 10mm wide half round, 8mm wide triangular, 4mm wide square, 4mm dia. round, each approx. 100 mm length of cut, without handle.

Files of other sizes and shapes are also available.

For mixing & grinding, electrically operated having capacity of few gms to 1 KG & 2 KG. Fitted with geared motor with max speed of 80 rpm. The jar is made of SS and having steel balls of different sizes to be put in jar for mixing & grinding pesticides power. Jar is interchangeable and easily removable, light in weight and compact unit working on 220 V AC with 1 KG cap.

Hand Operated without gas cylinder for sealing, but supplied with gas burner (Filling capacity from 10ml to 50ml)

(PH-4501-a)
Same as above but completely motorised with capacity adjustments.
