7. Brennenstuhl Schuko plug in power monitor
Display type: LCD
Number of phases: 1
Accuracy: ±1%
Minimum temperature: -10°C
Encoder type: Digital
PM231 - Power Meter. The Primera-Line PM 231 E power and current meter saves costs and electricity. This power meter is mounted in wall sockets and measures voltage, frequency, current, efficiency, power factor, and output power. It calculates total energy consumption and energy costs, displaying the measurement time in hours and minutes. It features two individually adjustable electricity tariffs (day and night) and includes three LR44 batteries for data storage in case of a power outage. The device has a child-safe socket and is available in various socket types: UK version, French version, and German version.
8. Eltako Alternating current meter
Only calibrated meters are approved for electricity billing according to §25 of the German Calibration Act. Non-compliance is an administrative offense under §19. Maximum current is 32A, with a standby loss of only 0.4 watts. This is a modular device for mounting on DIN-EN 60715 TH35 mounting rails. 1 division unit = 18mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. This alternating current meter measures active energy based on the current flowing between the input and output. The self-consumption of only a maximum of 0.4 watts of active power is not measured and not displayed. One external conductor with a current of up to 32A can be connected. The starting current is 20mA. If a load of more than 50% is expected, a ventilation distance of 1/2 division unit must be maintained from adjacent mounted devices. If necessary, use the spacer DS12. Two N terminals for secure cross-wiring of multiple meters. The 7-segment LC display can also be shown twice within two seconds without power supply.
9. Voltcraft Mechanischer Handzähler
The mechanical hand counter from Voltcraft is a precise instrument for recording counting processes, making it ideal for tracking movements, items, or people. With a handy, chrome-plated metal housing, it offers both durability and an appealing appearance. The detachable mounting plate allows for easy table installation, enabling the counter to be used flexibly in various environments. The counting range extends from 0 to 9999, and resetting is conveniently done via a button. This device is particularly useful for applications where accurate counting is required.
- Precise counting of up to 9999 units
- Handy and robust metal housing
- Easy table installation with detachable plate
- Reset via practical button.
10. LogiLink Check
The LogiLink Outdoor Energy Cost Meter (EM0007) is a practical solution for monitoring the electricity consumption and costs of outdoor electrical devices, such as garden lighting or pond pumps. Many of these devices are unnoticed energy guzzlers, making it difficult to estimate their consumption and costs. The EM0007 addresses this issue by simply being plugged in between the outlet and the device. It accurately measures (±2% accuracy) the current power consumption (watts), voltage (volts), total consumption (kWh), and usage duration. A key feature is the ability to input your personal electricity tariff. This allows the device to calculate the exact operating costs and display them on the large, easy-to-read 2-inch LCD screen. Operation is straightforward with three buttons that allow navigation through five different display modes, enabling real-time monitoring.
