PCE-ATP 1 is a food safety / hygiene - ATP tester, ATP meter, lumitester or luminometer used for surface testing. This luminometer allows for quick and easy first-generation adenosine triphosphate (ATP) testing and monitoring to ensure proper cleanliness, sterilization and sanitization. PCE-ATP 1 is an ATP tester that can be used for cleanliness control and documentation in many different applications.

• Measurement range: 0 … 999,999 relative light units (RLUs)
• Stores up to 10,000 date- and time-stamped data records to internal memory
• Enables rapid detection of bacterial or microbial residue

PCE-PCO 2 is a portable handheld airborne particle-counting hygiene meter or particle counter used to monitor particulate matter (PM) concentrations in the air. Designed to aid in indoor air quality (IAQ) assessments, this particle counter also measures air temperature, dew point and relative humidity.

• PM channels:PM 2.5, PM 10, including mass concentration mode (µg/m³)
• Particle sizes (in micrometers): 0.3 µm, 0.5 µm, 1.0 µm, 2.5 µm, 5.0 µm, 10 µm
• Temp. measuring range: 0 … +50 °C / +32 … +122 °F
• Humidity measuring range: 0 … 100 % RH
• Built-in camera for image and video recording
