A highly versatile power supply for all low-voltage experiments, with continuous voltage adjustment, separate for DC and AC. The two outputs can be loaded simultaneously without interference. Four digital displays show DC and AC voltage and current. The continuously adjustable DC current limiter can be set using a screwdriver. There is an LED indicator to show when the selected maximum current is reached. The power supply also features electronic overload protection. Specifications DC Output voltage: 0-24 V (stabilised) Ripple and noise (max): 25 mVpp Output current (max): 10 A (0-12 V) Max output current falls linearly to 6 A at 24 V Electronic, continuously adjustable current limiter, adjusted with screwdriver AC Output voltage: 0-24 V (stabilised sine) Output current (max): 6 A Electronic current limiter

The perfect choice for experiments with, for example, electron beam tubes requiring voltages up to 500 V DC at a low current level. The unit also provides two auxiliary outputs: A continuously variable negative voltage (down to -50 V DC), series connected with the 500 V output, and a stepwise selectable AC voltage with galvanic isolation from the DC outputs. Continuous adjustment of the -50 V and 500 V voltages. The current is limited to 50 mA. Voltage and current can be read from separate displays. A switch selects which output to monitor. The AC output delivers up to 3 A and is provided with a thermo fuse. Note: Not recommended for students due to high output current. Specifications Negative DC voltage: 0 to -50 V Current (max): 50 mA Positive DC voltage: 0 to +500 V Current (max): 50 mA Ripple: less than 0.1% Regulation: Better than 1 % for variations in mains voltage and load up to 10 %. AC Voltage: 2 to 7 V (1 V steps) Current (max): 3 A

This power supply delivers stabilised DC voltage, continuously adjustable between 0 and 6 kV. For safety, the current is limited by a built-in series resistance. The short-circuit current is 2 mA max. Under load, the voltmeter shows the actual supplied voltage. The power supply is also capable of delivering 6.3 V (max. 3 A) AC. This is the standard voltage for many electron tubes etc. On the front, you find a yellow/green ground socket, connected to the metal enclosure and hence (through the mains wire) to earth. The high voltage section floats relative to ground, allowing either the black (negative) socket or the red (positive) socket to be connected to ground, resulting in a voltage range of 0 to +6 kV resp. 0 to -6 kV relative to ground. Specifications •DC Voltage: 0 - 6 kV. Stabilised, continuously adjustable •Short-circuit current (max): 2 mA •Ripple and noise (max): 1% (RMS, 100 V - 6 kV) •Read-out precision: 1% + 1 digit •AC Voltage: 6.3 V •Current (max): 3 A

This power supply delivers stabilised DC, continuously adjustable from 0 to 12 V. It also supplies AC, selectable between 2, 4, 6 and 12 V. The AC voltage is not stabilised. Both outputs have overload protection. The DC channel is electronically protected and automatically reconnects while the AC channel has a circuit breaker which must be manually reconnected if it trips. Specifications •DC Output voltage: 0 - 12 V (stabilised) •Ripple and noise (max.): 100 mV •Output current (max.): 3 A •AC Output voltage: 2, 4, 6, 12 V •Output current (max.): 3 A

A simple, robust and reliable power supply, ideal for basic electricity experiments. It offers stepped adjustment of both AC and DC with 1 V between the steps. The DC voltage is not smoothed or stabilised, meaning there is a fluctuation of approx. 10% of the output voltage at step level. The unit is protected against overload with an automatic circuit breaker (the unit works again after about 10 seconds). DC voltage: 1 to 12 in 1 V steps Current: 6 A max AC voltage: 1 to 12 in 1 V steps Current: 6 A max

This has to be the best signal/function generator available for educational use! Developed in conjunction with physics teachers and designed specifically for education, this unit provides all the functionality you need for physics teaching. really useful feature for those less familiar with using signal generators is that for basic use, you just operate two buttons: One for frequency and one for amplitude that's it! There is, of course, far more sophistication for those who require it. If you want to change waveform or to utilise the step and sweep modes, the display keeps you updated on the status of the generator. Unique frequency control: The frequency is set by speed sensitive button. Turn slowly to set the display's last digit, turn faster and the response accelerates designed to work intuitively in practical experiments. Drives speakers, vibration generator etc. directly: The built-in 10 power amplifier effortlessly drives power appliances e.g. vibration generator. The amplifier can deliver more than amp for all frequencies between 0.001 Hz and 100 kHz. Step mode: In many applications you need to study physical system at fundamental frequency and at different multiples of that frequency. The special step feature makes this task incredibly easy. Once the fundamental frequency has been determined (e.g. of spring connected to vibration generator), other harmonics (or overtones) can be demonstrated by simply pressing button, which changes the frequency to progressive multiples of the fundamental frequency. Sweep mode: The generator can sweep through frequency range in order to discover eventual resonances. You decide the frequency range and the speed. You have the choice between linear sweep (fixed number of Hz per unit time) and logarithmic sweep (fixed number of octaves per unit time). Advanced Features: The generator connects to your PC through standard USB cable and acts as USB flash drive. Custom defined waveforms (e.g. created by means of spreadsheet) can be saved to the generator. Sequences of settings can be programmed for automatic execution.

Cobalt chloride free humidity indicator paper does not contain carcinogenic or toxic material. There is a clear colour change from yellow-green to pale to colourless at approximately 2% Humidity indicator paper traditionally contains cobalt chloride which is known for it’s toxic and carcinogenic properties Handling these indicator papers puts end users and those involved with packing them at risk This non-toxic moisture indicator paper disqualifies this risk being safer to use

Cobalt Chloride Test Paper can quickly and economically measure the presence of relative humidity in the atmosphere. The paper is directly exposed to the atmosphere and turns from blue to pink upon contact with relative humidity greater than 2%. These papers are traditionally used in school experiments.
