The power data logger (Graphic Power Quality Analyzer) PCE-GPA 62 is used for single-phase or three-phase measurements of the active, reactive and apparent power, power factor, phase angle, energy, voltage, current as well as peaks and harmonics.

• Real-time test, register and measurement of voltage and current (real and effective) 
• Measures power factor and phase angle, frequency, energy, active, reactive and apparent power   (single-phase or three-phase in symmetrical networks). 
• Max. conductor diameter: 55 mm / 2.2 in
• Records up to 50,000 records

PCE-PCO 1 is a handheld data logger for measuring the concentration of particles in the air. The PCE-PCO 1 data logger:

• Measures 6 sizes of particles: 0.3 µm, 0.5 µm, 1.0 µm, 2.5 µm, 5.0 µm, 10 µm
• Offers a robust, 80 MB internal memory
• Features a large, full-color LCD display with backlight
• Includes a built-in camera for image and video recording
• Contains sensors for measuring air temperature, dew point and relative  humidity
• Displays temperature in degrees Celsius (°C) or Fahrenheit (°F)

The PCE-HT 71N Data Logger detects air temperature and humidity and stores readings to its internal memory. This Data Logger is compact and has enough memory to store up to 32,000 readings, 16,000 for each parameter, and is used above all as a Data Logger, in supermarket refrigeration units, refrigerated transport, warehouses and other temperature controlled environments. These temperature and humidity logging test instruments are manufacturer calibrated. An ISO calibration certificate is an option.
