| Description | Code: OPR1221
Pack of 10 12V 21W Small Bayonet Cap (SBC) Radial Filament Lamps.
| Code: EPU0115
The Powerlock power supply has both a lockable AC and DC outputs ranges by a simple key making it impossible for students to change the voltage. The Powerlock offers 2,4,6,8,10 and 12 in both DC and AC. Outputs may also be used simultaneously up to the rated output required. For safety, the output is also protected by a simple push button cut-out. Each unit is supplied with 2 that can be used on all Powerlock units if needed. Supplied with 2 keys.
| Code: EPT5001
(Portable Appliance Tester and Checker). Performs electrical safety tests on portable appliances allowing compliance with EAWA regulations. The unit performs earth bond and insulation tests on both Class 1 and Class 2 appliances, extension leads, IEC and kettle leads etc. The unit is very simple to operate and gives clear, unambiguous pass/fail indications. Complete with test leads, instructions, pass and fail labels, a Tester's Certificate of Inspection and is fitted with moulded mains plug.
| Code: ERS8050
A six-decade resistance substitution box designed for use in educational establishments.
| Code: EPC7000
A multipurpose unit that allows the user to easily calculate Planck's constant, to measure the wavelength of coloured light, demonstrate colour light transmission through colour filters and show the diffraction patterns for various wavelengths of coloured light using a range of 4 LEDs (Red, Yellow, Green and Blue) covering the light range from deep blue at 470nm to near IR at 940nm.
| Code: EPU0201
A very popular and compact Westminster power supply that is ideal for school use in Key stage 4 and 5 physics lessons with its tough steel case protected by a tough powder coated finish that will last years of use. The unit will deliver up to 16A AC or DC through its colour coded terminal posts. This power supply is very popular for use in electromagnet experiments.

A simple to use PAT machine that allows the user to perform Class1 and Class 2 insulation tests, earth bond tests at two different current levels and extension lead tests. The compact unit clearly displays the results via coloured LEDs. A single push button initiates all the tests in a 5-second cycle.
•Class 1 Earth Bond test
•Class 1 and Class 2 Electrical Insulation test
•Mains switch and circuitry test
•Extension Lead test
•IEC lead test
•Results are displayed by coloured LEDs. Timed test period.
Comes complete with 100 pass labels, 50 fail labels, Earth Bond Test lead, Extension lead test lead and full instructions including sample inspection certificate.
