1 MAINS DIGITAL JOULEMETER BASIC can be used to measure the power and energy consumption of a wide range of mains devices (up to a maximum power of 3750 W). The display shows values of voltage (V), current (A), power (W), frequency (Hz) and energy (kWh). It is straightforward to use, and simply pressing one of the buttons changes the display to show the quantity selected. There are many useful activities on measuring power that can be done quickly in the classroom, for example, looking at the difference between ordinary and energy-efficient light bulbs, or at the power reduction when a computer is switched into standby mode. The monitor can also be used over longer periods of time to measure total energy consumption, for example, the energy needed to run a refrigerator and whether this depends on how full it is or on the temperature of the room. Cat No. Description Price Per HEM-250-100 Mains Digital Joulemeter - Basic 26.13 ea. 2 PSU BASE POWER/ENERGY METER - MAINS VOLTAGE (AC) -NEW! This mains voltage Power / Energy meter from PSU Base can be used to measure power and other electrical parameters of any mains appliance (220- 240V AC) e.g. kettles, water baths, hot plates etc. The meter has a large back lit LCD display and tough ABS housing. The power input, to power the unit and ‘load’, is via a 3-pin mains plug lead. The load or output to be measured is simply plugged into the integral mains socket on the front of the unit. Supplied with 13A input socket and mains cable. • The current flowing through the load (A) • The power dissipated by the load (W) • The amount of energy converted by the load (Watt-hour or Wh, which can be converted to Joules by multiplying by 3600 Cat No. Description Price Per HEM-470-100 Power/Energy meter - Mains Voltage (AC) 59.90 ea. 3 DIGITAL JOULEMETER - BASIC This Joule meter / Energy meter measures the voltage, current, power, energy and time for a low voltage load, such as an immersion heater, bulb or motor and also calculates the equivalent mass of CO 2 released during use, corresponding to the electrical energy consumed. The meter can measure and display the following parameters: • The voltage across the load (V)

4 PSU BASE POWER/ENERGY METER - LOW VOLTAGE DC -NEW! This low voltage Power / Energy meter from PSU Base has a large back lit LCD display and two pairs of 4mm sockets – one pair for the input power and one pair for the ‘load’ (output) to be measured (e.g. a low voltage lamp, immersion heater etc.). The input, to power the unit and ‘load’, can be anything from 6.5 to 100 Volts DC and the load (output) can safely draw up to 20 Amps. • The current flowing through the load (A) • The power dissipated by the load (W) • The amount of energy converted by the load (Watt-hour or Wh, which can be converted to Joules by multiplying by 3600) Cat No. Description Price Per HEM-450-100 Power/Energy meter - Low Voltage DC 49.90 ea. The meter can measure and display the following parameters: • The voltage across the load (V)
